[00:56] <canurabus> Hi all. I tried to install (k)ubuntu 18.04 to a usb flash drive but its unusably slow. The install itself took a couple of hours and it takes about 15 minutes just to boot to login. After logging in, I haven't bothered waiting long enough to wait for the desktop to load (+30mins...)
[00:56] <qwebirc22304> how old is your machine ?
[00:56] <canurabus> The drive is USB 3 and I was hoping it would be fast enough to use
[00:56] <canurabus> Fairly recent, its a Dell XPS 13 I bought a year ago. It has 2x usb 3.0 and 1x thunderbolt
[00:57] <qwebirc22304> OK. I was more checking for RAM capacity
[00:57] <qwebirc22304> 1 year old is fine
[00:58] <qwebirc22304> maybe the kernel somehow is not setup to use the usb3 and ou end up with very low usb1 controller speed or worse...
[00:58] <qwebirc22304> did you try using a usb2 drive ?
[00:59] <canurabus> I used a USB2 live install disk to do the installtion to the USB3 drive and that seemed reasonably fast
[00:59] <canurabus> But I don't have a USB2 drive big enough to do a full install on
[01:00] <qwebirc22304> I see. I don't know much of latest ubuntu/kernels unfortunately. Connected to get some help with a boot issue when using Nvidia drivers
[01:00] <qwebirc22304> I am very rusted (no issues in ~9years when I used my previous PC). I can't even find some key logs !
[01:00] <canurabus> good old nvidia trouble
[01:01] <canurabus> scour the xorg log for errors, copy and paste into google, waste X hours etc etc
[01:02] <canurabus> though tbh ive had a mostly decent experience with nvidia drivers
[01:04] <qwebirc22304> the xorg log is not present anywhere
[01:04] <qwebirc22304> I have an old xorg.log in ~username/.local/share/xorg/*
[01:04] <qwebirc22304> but not correct date
[01:05] <qwebirc22304> I removed those old ones, restarted : no X logs
[01:05] <qwebirc22304> so somehow X is not even loaded
[01:05] <qwebirc22304> but I can't find any error anywhere (no errors in /var/log/syslog, nor kern.log, nor systemctl -xb)
[01:06] <qwebirc22304> I am stuck: no log, no error...
[01:08] <canurabus> I don't remember exactly what to do but what happens if you try to start x manually?
[01:08] <canurabus> Also maybe the logs are now part of journalctl?
[01:08] <canurabus> or journald or whatever its called
[01:08] <qwebirc22304> apt-get purge Nvidia* , reboot, hop I get a gnome session. But I am on nouveau
[01:09] <qwebirc22304> can't use a video editing software that I have with that
[01:09] <qwebirc22304> and I get back Xorg log in my user. So I am using X11
[01:21] <Ookma-Kyi> help
[01:22] <TimeDoctor> Ookma-Kyi: please ask your question
[01:22] <Ookma-Kyi> I need to undo this: sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/
[01:22] <Bashing-om> qwebirc22304: what shows ' echo $XDG_SESSION_TYPE ' ?
[01:23] <TimeDoctor> Ookma-Kyi: rm /etc/nginx/sites-enabled/example.com
[01:23] <Ookma-Kyi> ok ty
[01:23] <TimeDoctor> as root, so, sudo it
[01:49] <Ookma-Kyi> ok anyone here know how to stop certbot from servicing my previous domain?
[01:52] <EriC^^> Ookma-Kyi: i think it uses some cronjob
[01:52] <canurabus> I tested the r/w speed on my drive and its (100/40 MB/s). Looking at dmesg output, the line "EXT4-fs (sda2): mounted filesystem with ordered data mode. Opts: (null)" takes 280 seconds. Anyone know what could be causing such a huge delay? ANy logs or something I can look at etc
[03:16] <gambl0re> i plan on getting a new external monitor for my laptop. will i have to download some drivers in order for my desktop monitor to display full resoultion or should it work straight out the box?
[03:34] <pagetelegram> anyone know how to get gobi 3000 modem to work?

[04:05] <Talsin> i want to remove all traces of snap and snapd, how can i remove the snap core ?
[04:06] <Talsin> sudo snap remove core --revision 5330      -- doesnt work
[04:07] <MrCrackPotBuilde> try with the purge option
[04:08] <MrCrackPotBuilde> sudo apt autoremove --purge snapd
[04:09] <Talsin> that did it thanks
[04:12] <Bashing-om> Talsin: Might want to remove a bit more : https://ubuntuforums.org/showthread.php?t=2328152 .
[04:16] <Talsin> nah, got what i needed, removed snap and the "core snap", waste of ram on a server
[04:32] <MrCrackPotBuilde> auto remove should remove its dependencies along with the application

[06:30] <boblamont> For the past little while, I've been getting "ALSA error: snd_mixer_attach failed: Connection refused." intermittenrly. I can solve it with pulseaudio -k followed by pulseaudio -v, but it would be nice to just stop it from happeneing. It may have started when I plugged in an imic usb audio interface.
[07:08] <marataziat> Are there linux alternatives for https://www.producthunt.com/alternatives/helium-3 ?
[07:21] <hateball> marataziat: If GNOME has an option for always keeping a window on top, that seems like it is what that thing does
[07:21] <hateball> KDE Plasma (well kwin) lets you set such options
[07:21] <gambl0r3> i plan on getting a new external monitor for my laptop. will i have to download some drivers in order for my desktop monitor to display full resoultion or should it work straight out the box?
[07:22] <hateball> gambl0r3: it should just work
[07:23] <hateball> but if you intend to use different DPI settings for the internal and external screens you are not going to have a nice time
[07:23] <gambl0r3> hateball, what do you mean?
[07:25] <gambl0r3> my laptop has a 1366 x 768. my external will be a 2560 x 1440 resolution
[07:25] <gambl0r3> will that cause problems?
[07:30] <hateball> gambl0r3: the resolution will not be a problem most likely, but if you wanted to have different DPI on both screens that would be a problem
[07:30] <hateball> gambl0r3: for instance, I am guessing GNOME uses a 96DPI default tho I may be wrong. Now if you use a 4K monitor some might find that too small for text, and as such would want to adjust DPI
[07:33] <gambl0r3> i plan on getting a 27" wqhd 2560 x 1440 resolution.
[07:40] <hateball> gambl0r3: you should be just fine
[08:04] <Edisto> Where can I find kernel 4.15.0-33?
[08:04] <Edisto> I'm having issues  booting iwth 4.15.0-34 and amdgpu-pro
[08:10] <nwe> Edisto: kernel.org
[08:15] <Edisto> nwe: i don't see a list on the site >.<
[08:17] <Edisto> hmm... i really don't want to use amdgpu-pro if it is going to break every .01 difference in update. They need to come up with a opencl 1.2 that is open source
[08:18] <nwe> I mean kernel 4.15 ( the vanilla kernel). grab it and  build it by yourself. otherwise you should try too downgrade kernel..
[08:19] <Edisto> http://kernel.ubuntu.com/~kernel-ppa/mainline/ doesn't have any previous versions or even 34

[09:23] <gpap> i would like to add one more problem with ubuntu 18.04 and gnome 3. I was trying to manage the high memory usage into my 4gb ram system, by hitting alt+f2  and then typing r
[09:23] <linux> hi guys ,what are the easiest commands to reinstall grub from livecd ??
[09:23] <gpap> to restart my gnome session
[09:25] <gpap> after this command my system hanged and even after rebooting i was stopped at the boot splashscreen, leaving gnome 3 totaly unusable. So i reverted in kde, witch is working normaly
[09:55] <pragomer> I have two audio cds that do not open in ubuntu 18.04

[10:00] <yossarianuk> hi - running 18.04 - I am trying to use Virgil in KVM - however I get the message 'This QEMU doesn't support spice OpenGL'
[10:00] <yossarianuk> is this feature missing from the ubuntu packages ?
[10:05] <welcomeparty> Hi guys, I have an issue with my slowdown performance on my ubuntu 18.04 LTS(GNOME) when using second external monitor, it seems so laggy. Do you have an idea why?
[10:07] <tomreyn> welcomeparty: which graphics card and driver is in use, how's the external monitor connected, is there anything about it on "dmesg -w" (unplug monitor, run this command, plug in monitor, see messages printed)
[10:12] <BluesKaj> Hi folks
[10:12] <welcomeparty> @tomreyn http://termbin.com/hq72 regarding my installed drivers
[10:13] <welcomeparty> processor: AMD 7th Gen APU A12-9700P Quad Core, GPU: Radeon R8 M435DX Dual Graphics
[10:14] <welcomeparty> i tried to check on AMD supported drivers list, mine is not on the list
[10:14] <welcomeparty> and since it is APU, even my APU only supported for windows
[10:22] <welcomeparty> @tomreyn this is the dmesg output after repluggin the hdmi port monitor http://termbin.com/hsum
[10:23] <welcomeparty> i dont know what caused it, maybe unsync hardware compatibility which reduces frame rate?
[10:24] <welcomeparty> when i use the built in laptop monitor the performance suddenly back to normal
[10:26] <tomreyn> welcomeparty: could it be that the DC cable is just bad?
[10:28] <tomreyn> does this also happen after a clean boot, without the system going into / returning from standby / hibernation?
[10:29] <tomreyn> the drivers seems to have been reinitialized a couple times, maybe /var/log/syslog has more information on why this is.
[10:29] <tomreyn> * driveR

[11:32] <JuJUBee> does iptables have some limitation on filesize for download?
[11:33] <SwedeMike> JuJUBee: you mean the amount of total traffic one can transfer per session? I have never heard of anything like that, no.
[11:34] <JuJUBee> SwedeMike, I am getting network errors when I try to download files to my classroom computers, but the server itself has no problem
[11:34] <SwedeMike> JuJUBee: what makes you think this has to do with filesize?
[11:35] <JuJUBee> I'm just trying to figure this out.

[13:36] <aruns> I will check /etc/network/interfaces
[13:38] <pagetelegram> genii, got the woeusb with updated PPA thanks
[13:41] <lotus|NUC> aruns: join #ubuntu-server volunteers might take a look at your issue
[13:42] <aruns> OK, thanks lotus|NUC
[13:45] <antal> aruns: you will have a blast, the keyword you are looking for is "netplan", that's the new system handling the network, good luck
[13:49] <jeromelanteri> Hi, i have a problem to configure network. It was working (ubuntu-18.04) but no more now. i have mate desktop and networkmanager, but i read also some networking systemd and netplan... this make me confuse. The mate config GUI for network doesn't start anymore (error)... Could you help me to resolve my problem please ?
[13:51] <jeromelanteri> ho also, i do config eth0 (no wifi, it is a ethernet connection), and he can see the router, but no internet (broadcast stay 0.0.0.0 instead of 192.168.2.1)
[13:54] <jeromelanteri> kernel 4.14-69-148
[13:54] <pagetelegram> woeusb creates thumb that boots to grub prompt....no idea what to do there.
[13:55] <lotus|NUC> pagetelegram: woeusb is not officially supported by the ubuntu community, ask the maintainer please
[13:56] <mouses> pagetelegram: for creating a bootable USB stick from ISO, I highly recommend etcher.io
[13:57] <mouses> https://etcher.io/
[13:57] <pagetelegram> I've used etcher before, last time I used it it didn't create a bootable USB from DVD ISO file.
[13:58] <pagetelegram> I'll try again, tho frankly I keep hitting dead ends. I hope I'm wrong trying etcher again
[13:58] <pagetelegram> thanks
[13:58] <coz_> there is also, throguh flatpak, fedora media writer,
[13:59] <coz_> as far as I can tell, it's perfect
[13:59] <coz_> not sure, and doubtful it
[13:59] <coz_> is in the ubuntu repos
[13:59] <pagetelegram> thanks
[14:01] <coz_> pagetelegram, check your repo for FMW or fedora media writer, it would be interesting to see if it is there
[14:02] <pagetelegram> not a default in PPAs. Going to look for a PPA to add.
[14:04] <coz_> dont think it is on a ppa
[14:05] <coz_> pagetelegram, I dont think its on a ppa, and not sure about installation on ubuntu, however with flappak    flatpak install flathub org.fedoraproject.MediaWriter
[14:05] <coz_> pagetelegram,   then    flatpak run org.fedoraproject.MediaWriter
[14:06] <coz_> pagetelegram,  let me know if it works, if you try it
[14:07] <pagetelegram> "error: app/org.fedoraproject.MediaWriter/x86_64/master not installed"
[14:08] <coz_> darrn
[14:08] <coz_> pagetelegram, that's a real shame, fmw is one of the best I have tried
[14:08] <coz_> let me check
[14:10] <coz_> pagetelegram, I cant find an ubuntu ppa or installation , you may be stuck with etcher, which is also real nice
[14:11] <hateball> pagetelegram: personally I just use dd
[14:11] <lotus|NUC> +1 hateball
[14:13] <pagetelegram> I think non will work I even tried DD before as well. I think all these tools do the same. Rufus does more, I think the new boot standard with BIOS efii or something is the issue
[14:13] <jeromelanteri> no help with network ?
[14:14] <lotus|NUC> jeromelanteri: to get your issue solved, try to re-ask your question with all details in one line, once in a while
[14:15] <pagetelegram> That is my chief issue is no help yet with getting GSM modem to work. Which is why I'm meandering different distros. Need Sierra Gobi 2000 supported for 3G internet access. Cause the alternative is an unreliable WIFI connection
[14:17] <jeromelanteri> ok, ubuntu-18.04 mate desktop GUI etwork config can not start (error), i have networkmanager and networkd and netplan installed... i disable networkd (i supposed to use networkmanager only because of GUI mate tools). I arrived to setup a eth0 IPv4, but no broadcast config (0.0.0.0 isntead of 192.168.2.1). I'm searching for an help and netplan/networkd make me fell very confused.
[14:18] <jeromelanteri> lotus|NUC, is it more clear and suffisant ?
[14:18] <lotus|NUC> jeromelanteri: thats good mate, now be patient if someone knows they surely will help
[14:19] <jeromelanteri> lotus|NUC, ok. I think it is maybe related with new netplan/networkd against networkmanager... maybe...
[14:31] <Talsin> what is best way to stop the iscsid from starting on boot without doing 'sudo apt remove open-iscsi' ?
[14:32] <jeromelanteri> sudo systemctl diable
[14:32] <jeromelanteri> disable
[14:32] <adrian_1908> Talsin: I'm not familiar with it, but if it's launched by a systemd unit, what jeromelanteri said should work.
[14:32] <Talsin> thanks
[14:33] <Talsin> cheers
[14:33] <jeromelanteri> Talsin, you should find it (if it is a systemd deamon) by command: sudo systemctl status (then search)
[14:34] <Talsin> cool, yeah i got it this once with 'sudo /etc/init.d/iscsid stop', but i dont wanna do that every boot
[14:34] <jeromelanteri> and then, the most used commands for systemctl (as systemd control) are: mask, unmask, enable, disable, start stop status, and --failed.
[14:35] <jeromelanteri> init.d method is the "old" system V one method
[14:35] <jeromelanteri> or BSD one
[14:35] <Talsin> yeah i been away from linux a long time
[14:35] <Talsin> lol
[14:35] <jeromelanteri> welcome back
[14:45] <ilias_gr> hi all. does any one maybe know where are stored notification area (sys tray) icons for skype ?
[14:48] <jeromelanteri> ilias_gr, not really, it can be any places... but there is a command tool for find that... it is "find"
[14:49] <mouses> Morning, everyone - having a crazy problem that I have been trying to solve for over a year now on Xubuntu 16.04 - anywhere from 5 mins to sometimes hours after bootup, I experience very strange graphical corruption.  In terminals, I get weird corruption like this: https://imgtc.com/a/Lh7O4HT ->  this corruption also shows in applications (for example, when scrolling a list of files in Thunar, letters will be
[14:49] <mouses> drawn 'on top' of eachother).  So far I have tried - memtest86 (10 passes, all clear), disabling compositing, changing system fonts, different terminal emulators, a full re-install of the OS, returning the system for refurb and having it replaced, ... no matter what I do, I get this issue.
[14:50] <mouses> The fact that the corruption is visable in xfce4-screenshooter leads me to think this has to be something to do with xorg, but I am just totally stuck on this.  Anyone had any ideas of where I could start?
[14:50] <ilias_gr> jeromelanteri: i want to locate/find where those icons are stored to replace thme with faenza icons because the system does not replaced them automattically
[14:50] <jeromelanteri> ilias_gr, so with find: sudo find / -type f -name "*skype*" &2>/dev/null
[14:51] <ilias_gr> jeromelanteri: locate also do the job, isn't it?
[14:51] <jeromelanteri> or more localy it can be earched inside /usr/local/share, or /usr/share or /home/your_user_name
[14:51] <jeromelanteri> locate is not so powerfull than find, because 1/ you have to rrefresh a database and 2/ he search in home dir
[14:52] <jeromelanteri> find is just perfect
[14:52] <Talsin> mouses: is your graphics chip or graphics ram overheating ?
[14:53] <mouses> Talsin: Forgot to mention that = no, checked all temps - 100% in normal range.  This can even happen on a cold system (hours without power, and then suddenly 5 mins after boot)
[14:53] <mouses> Talsin: it's making me crazy lol - literally tried everything I could think of or google for a year now, including totally replacing the hardware.  Still happens.
[14:53] <Talsin> mouse the time delay is what makes me suspect heating
[14:53] <ilias_gr> jeromelanteri: i am looking for 3 icons. The first show the use active, the 2nd in "do not disturb" option and the 3rd "invisible". which is the best way/command to use find to locate them?
[14:54] <jeromelanteri> ilias_gr, there is also an option for find for he doesn't go to search out of the mounted file system where you define the directory target
[14:55] <mouses> Talsin: Yeah, I wish it was a heat thing - this system runs cold and nice even with booted for weeks
[14:55] <jeromelanteri> ilias_gr, the best command should be relative to user conception of what is the best. Best can be quick or exhaustive or/and any other considerations
[14:55] <Talsin> ilias_gr: try the find command suggested, or find / | grep -i "\.ico$" 2>/dev/null
[14:56] <ilias_gr> jeromelanteri: i tried with the command you wrote above but nothing was returned
[14:56] <jeromelanteri> so for me, best should be to target the possible dirs... /usr/share, /usr/locale/share, /home/user_name
[14:56] <jeromelanteri> (so 3 commands)
[14:56] <ilias_gr> Talsin: it is not sure that the extension is .ico
[14:56] <jeromelanteri> ilias_gr, also do you have an idea of the name of this icon you are searching for ?
[14:57] <jeromelanteri> ilias_gr, or with what it was installed ?
[14:57] <Talsin> try .png .jpg .bmp    .... use your initiative
[14:57] <ilias_gr> jeromelanteri: maybe "invisible"
[14:57] <jeromelanteri> .ico
[14:57] <ilias_gr> or something like that
[14:57] <jeromelanteri> there is also an option for "not visible file"
[14:58] <jeromelanteri> it should NOT be a file start by "."
[14:58] <Talsin> mouses are you sure your video chipset is fully supported ?
[14:58] <jeromelanteri> an other one idea is to use the package manager good option to find dpendencies files of the package installed...
[14:58] <mouses> Talsin: I assume so - how would one check that?
[14:59] <Talsin> mouses read that fine manual, hehehe
[14:59] <mouses> grrrrr
[14:59] <mouses> fair answer :)
[14:59] <ilias_gr> jeromelanteri: i used Software to install it
[14:59] <Talsin> mouse actually i'd start with /var/log
[14:59] <jeromelanteri> mouses, a lspci should give the first info to search for... then from the manufacturer web site, you should find for linux support more informations...
[15:00] <jeromelanteri> ilias_gr, which Software ?
[15:01] <mouses> yeah, on it :)  thanks Talsin and jeromelanteri
[15:01] <yuggniiks> I just purchased the Ubuntu 18.04 LTS Server book.   In it they describe that accessing Samba shares from Windows 10 is an issue (for windows 10).  It then goes on to show how to do it, but I'm not able to follow the steps.  Does anyone have a good resource for this?
[15:01] <ilias_gr> jeromelanteri: Software 3.20.5 "A nice way to manage the software on your system"
[15:02] <jeromelanteri> ilias_gr, ho ok, i don't know this application. does it search for maintened distro packages or does it go for install source files from somewhere ?
[15:03] <jeromelanteri> anyway, you can use package manager (so apt for ubuntu) to search if there is a package name for skype there ?
[15:03] <jeromelanteri> then read the man page of apt for find the best option to show dependencies files of this pskype package
[15:04] <jeromelanteri> if it is source file installed, then you should be able to localte it (most probably inside /usr/locale/share OR /opt/)
[15:05] <jeromelanteri> ilias_gr, for exemple, try: apt list --installed | grep skype
[15:05] <Younder> Man pages are a pain. You can't tree's for the forest. I someties think it is the tire market concept between O'Reilly's series.
[15:06] <jeromelanteri> Younder, i understand what you mean... but that really depend of manual pages and your knowledge of man command tool.
[15:06] <ilias_gr> jeromelanteri: the system returns: WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
[15:06] <jeromelanteri> wow
[15:07] <Talsin> i like man pages, omg who remember the 'info' doc system, does that still even get used ?
[15:07] <jeromelanteri> ilias_gr, well, i'm a ubuntu/debian beginer. Usually i'm on archlinux or archlab or FreeBSD
[15:07] <Talsin> oh wow yes info is on my system
[15:08] <jeromelanteri> so why you rCLI is unstable ? i don' know...
[15:08] <Younder> Talsin, info just uses man if nothing else is available
[15:08] <jeromelanteri> Talsin, BSD hold some old fashion style for any good reason if you like that...
[15:08] <Younder> EMACS is sort of a slowly falling star yes
[15:09] <Talsin> info is like emacs it's amazing if you care to spend weeks/months learning to use it
[15:09] <jeromelanteri> emacs is a owerfull editor for devs
[15:09] <ilias_gr> jeromelanteri: look...i found thousands of png icons and i am trying to locate those 3 icons. wait a moment plz
[15:09] <Talsin> ive heard people call emacs an operating system, lol
[15:09] <jeromelanteri> and emacs has also spacemacs for emacs beginners and can have evil mode for vim users (because we love vim)
[15:10] <Younder> info work's best if you are familiar the the emacs command shortcuts.
[15:10] <jeromelanteri> ilias_gr, good
[15:10] <Talsin> vim is life
[15:11] <jeromelanteri> vim is efficient and so quick, yes. but also emacs is very good for dev things. emacsis like a powerfull IDE
[15:11] <jeromelanteri> and if you use them with tmux... woooooow
[15:12] <Younder> GNU EMACS - Generally Not Used Except for Middle Aged Computer Scientists ;)
[15:12] <jeromelanteri> and i3 desktop... OMG !!!
[15:12] <jeromelanteri> Younder, i think you should change d by g actually.
[15:13] <jeromelanteri> well... i still very confuse with my network and this netplan/networking vs networmanager things on ubuntu. no helo there ?
[15:13] <Talsin> yeah BSD has a great rep, i looked at FreeBSD for a while, but im lazy, linux is familiar, and ubuntu is easy
[15:14] <jeromelanteri> Talsin, bah actualy for e archlinux is easy and understandable and ubuntu is... well... unfamilliar and sometime starnge.
[15:15] <jeromelanteri> FreeBSD is strong and stable, and have powerfull tools like poudriere
[15:15] <Talsin> heh well i came from oldschool debian,
[15:15] <Younder> jeromelanteri, Well network-manager is on Ubuntu desktop but lacking from Ubuntu server. Where you have to set things up manually.
[15:15] <Younder> I have both on my network.
[15:16] <jeromelanteri> Talsin, maybe you will also want to have a look to new concept of functional configured distro ?
[15:16] <Talsin> maybe...
[15:17] <jeromelanteri> like like NixOS
[15:17] <Talsin> i dunno what that entails
[15:17] <jeromelanteri> the idea is like what is haskell vs C++ for dev
[15:18] <jeromelanteri> but for maintain a distribution
[15:19] <jeromelanteri> NixOS has some container for install applications with there own libs, and has a kind of specific config file for automation updates
[15:19] <Talsin> just googled it, looks interesting
[15:20] <Talsin> but still another advantage of ubuntu is the wide userbase and support
[15:20] <Talsin> not just for tech help, but things like amazon EC2
[15:21] <jeromelanteri> well... it is late there in Thailand (for me). Yes good support, correct (that is why i use it for my odroid-xu4 ARM). Archlinux has a good wiki also.
[15:21] <jeromelanteri> i want to go to bed... wife is waiting for his lion.... bye friends.
[15:21] <Talsin> goodnight :)
[15:22] <Younder> For me that NVIDIA uses it for it DGX series workstation/servers is a big plus.
[15:23] <Talsin> heh a unix box that nivida chips work on?  unpossible !
[15:25] <Younder> Talsin, I've been using NVIDIA with unix for 6 years and it has always been supported. You need stem to play any serious games
[15:25] <Younder> steam
[15:26] <Younder> You need to install the NVIDIA drivers separately
[15:28] <Younder> There is also a NVIDIA dockeer that allows you combine NVIDIa and dokcer. (Might require a Titan)
[15:28] <ilias_gr> jeromelanteri: is it possible that those icons are inside the program and not in separate dir?
[15:35] <JimBuntu> ilias_gr, it is possible they are in a .so file
[15:37] <ilias_gr> JimBuntu: any idea to force the system read the faenza corresponding icons?
[15:39] <JimBuntu> It could be quite difficult. This would require looking at Skype and your specific distro/set up to understand how the icons are being called and from where. Sorry, I'm not a skype user.
[15:41] <yuggniiks> Hi.  Any experience with Samba share & Windows 10?   I've tried both the ubuntu 18.04 server book, and http://www.ubuntuboss.com/how-to-set-up-windows-file-shares-in-ubuntu-18-04-with-samba/ with no luck.
[15:42] <Talsin> good luck with that, MS deliberatly make it difficult, even if you get it working it will prob break again in a few weeks
[15:43] <ilias_gr> JimBuntu: i understand that and i have already some times changed the icons for other applications because the didn't change automatically. but now i cannot find those 3 icons and replace them with faenza corresponding icons (faenza has already icons for these status ie. online, do not disturbe, invisible etc)
[15:44] <Talsin> considered making your own icons? or downloading some free ones, might be faster
[15:46] <ilias_gr> Talsin: and put them where to be located from the system automatically instead of current icons?
[15:47] <Talsin> just a suggestion... you can decide the best use of your time
[15:49] <ilias_gr> i found this: https://askubuntu.com/questions/503267/change-skype-tray-icon but i am not sure if it will work under xenial and for current Skype's version (8.31.0.92)
[15:52] <Talsin> i glanced at that article,  /usr/share/pixmaps/skype/   isnt what you are looking for ?
[15:57] <ilias_gr> Talsin: there is no such directory
[15:58] <Talsin> try this
[15:59] <Talsin> hmm, what is the skype install package name ?
[15:59] <ilias_gr> Talsin: skypeforlinux or skype, plain
[16:00] <Talsin> so do dpkg -L skype
[16:00] <Talsin> list the package contents, you cant help but find the icon files, if they exist
[16:03] <ilias_gr> Talsin: it is not skype/skypeforlinux it is something under /snap but i cannot understand how or what
[16:03] <Talsin> oh god snap
[16:03] <Talsin> sorry snap is new to me, i understand its sandboxed apps, thats about it
[16:04] <Talsin> im not even on desktop, im a server guy with just a bash prompt
[16:04] <Talsin> i removed snap from my dev server yesterday
[16:05] <Talsin> note the point of sandboxed apps is to isolate them for the rest of system, thats why you cant find it
[16:06] <Talsin> its all probably in a compressed mountable filesystem file
[16:06] <pragmaticenigma> Talsin: If you aren't familiar with something, please avoid making assumptions
[16:07] <Talsin> ive seen that snap mounts loop filesystems
[16:07] <pragmaticenigma> Talsin: snaps are not compressed, depending on the build, they isolated from the rest of the system
[16:07] <Talsin> thats enough for the above statments to be true
[16:07] <nacc> ilias_gr: what is your question about the skype snap?
[16:10] <ilias_gr> nacc: i want to find the way to replace systray (xfce notification area) icons for skype from default to faenza corresponding icons
[16:11] <nacc> ilias_gr: using the snap? you need to contact the snap owner, iirc.
[16:12] <nacc> ilias_gr: `snap info skype`, see the contact line
[16:13] <ilias_gr> nacc: is it a snap application actually? i installed it through Software for Ubuntu
[16:13] <Talsin> well i dont see skype in 'apt search'
[16:14] <nacc> ilias_gr: `which skype`
[16:14] <pragmaticenigma> ilias_gr: There are presently two ways to install skype. One is from the .deb file downloaded from Microsoft, the other is via a snap in the Ubuntu Software center
[16:14] <nacc> ilias_gr: i don't know how you have it installed
[16:14] <ilias_gr> Talsin: it isn't in ubuntu software center too
[16:15] <nacc> ilias_gr: i'm guessing snap, unless you did it manually
[16:15] <Talsin> snap, he said  Ubuntu Software center, or words to that effect
[16:15] <ilias_gr> i didn't . i did it using Software application
[16:15] <Talsin> "words to that effect"
[16:15] <nacc> Talsin: please don't answer for other people, it's not helpful.
[16:16] <nacc> ilias_gr: run the command i suggested `which skype` to see the path
[16:17] <ilias_gr> nacc: /snap/bin/skype
[16:17] <nacc> ilias_gr: yes, that's a snap then :)
[16:17]  * Talsin coughs
[16:17] <nacc> ilias_gr: and snaps are distributed out of band (technically) with the distribution.
[16:17] <nacc> Talsin: just becuse you happened to be right, doesn't mean you were being helpfu.
[16:18] <ilias_gr> nacc: so i understand there is no way to make Faenza icon replace the default icons for systray
[16:18] <nacc> ilias_gr: so follow the contact info for the snap, if you want to modify it's behavior (skype developers maintain it, not ubuntu proper, afaik)
[16:18] <nacc> ilias_gr: you'd need to ask them, you could also ask in #snappy.
[16:18] <nacc> ilias_gr: if there's a generic replace icon thing, but i don't think there is
[16:19] <ilias_gr> nacc: i think too there is not
[16:19] <Talsin> i was being helpful in establishing after 1.5 hours and 5 people helping him he is using a snap
[16:19] <ilias_gr> i am sorry i waste your time. i mentioned that i used skype.
[16:20] <ilias_gr> i can live with default icons.
[16:20] <Talsin> ... you can decide the best use of your time
[16:20] <ilias_gr> but i just wonder why it is not possible.
[16:21] <Talsin> because snap applications are isolated from the rest of the system, making is safer to use but harder to customise
[16:21] <ilias_gr> is it skype available as a program through apt or synaptic. i think it is not
[16:21] <pragmaticenigma> Talsin: That isn't 100% true, please stop doing that
[16:22] <Talsin> what am i doing that you find disagreeable ?
[16:22] <ilias_gr> Talsin: i understand that. An i have to mention that i saw that the whole directory is locked!
[16:23] <ilias_gr> nacc: or maybe it is difficult to do it
[16:24] <pragmaticenigma> Talsin: You already claimed you know little about snap... then proceed to make remarks about it, claiming it's isolated, compressed, etc. If you aren't knowledgeable in a topic, then don't offer advice on it. let someone else who is familiar with it take over.
[16:24] <nacc> ilias_gr: a snap is a squashfs image, loopback mounted. So the application itself is readonly to your user. There might be configuration in ~/snap/ but it's per-app and so that's why you need to ask upstream
[16:25] <Talsin> pragmaticenigma have you ever been paid to provide tech support ?
[16:25] <pragmaticenigma> Talsin: Yes, for several years
[16:25] <nacc> Talsin: this the ubuntu support channel, volunteer drive. Please take this to #ubuntu-discuss
[16:25] <nacc> *driven
[16:27] <Talsin> so you understand the social, emotional and psychological desires of clients, and how to separate your desire to be technically correct from the clients need to understand in laymans terms ?
[16:27] <Talsin> ok im done now
[16:28] <ilias_gr> nacc: read only to root also
[16:29] <nacc> ilias_gr: yes, readonly mounted, which is not about permissions.
[16:33] <ilias_gr> nacc: and this is maybe the reason that although the use change icon pack though 'appearance' the default icons remain the same
[16:33] <ilias_gr> *user
[16:34] <nacc> ilias_gr: right, also 'confined' snaps don't even see your system. So their behavior is the same on every system (in theory) with the same snapd running. I believe skype is confined. "classic" snaps (not the default) are more like regular debs in that they can use the system files, etc.
[16:34] <nacc> ilias_gr: depending on the application/snap, they don't even necessarily see your home directory
[16:40] <Younder> snap gubers up the netstat with all these 'fake' ports
[16:40] <Younder> and 'ip add'
[16:40] <Younder> addr
[16:41] <Younder> There has to be a cleaner way of doing it.
[16:41] <Talsin> snap was using more cpu and memory than my actual 'app' on my server
[16:41] <nacc> Younder: please take rants elsewhere.
[16:41] <Younder> I prefer docker
[16:42] <nacc> Younder: docker is a different thing than snaps.
[16:42] <nacc> Talsin: do you mean snapd? do you have an actual support topic?
[16:42] <Talsin> yes snapd. no i was responding to a short digression related to the topic at hand
[16:43] <nacc> Younder: afaik, snaps do not do anything to `ip addr` output.
[16:44] <Younder> nacc no? 3: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000... There is also a 4
[16:46] <nacc> Younder: pretty sure that libvirt no?
[16:47] <Talsin> have to agree, are you running in a virtual machine ?
[16:47] <ilias_gr> so in conclusion snap applications doen't change theri default icons whne the user change system's icon pack through appearance ?
[16:47] <nacc> ilias_gr: it depends on the snap.
[16:47] <Younder> nacc, Might be one of the other provisioner's, but not libvirt per se
[16:47] <nacc> Younder: how do you know?
[16:48] <nacc> Younder: it is, afaik, not related to snaps at all
[16:49] <ilias_gr> ok, i think this is something must be change in future so the whole system will have the same icon pack for all the applications
[16:49] <nacc> ilias_gr: that's not the point of snaps.
[16:49] <Younder> krita uses it
[16:49] <nacc> ilias_gr: in any case, if you'd like to ask about snap design, pleae use #snappy
[16:49] <TJ-> Younder: virbr0 is owned/operated by libvirtd
[16:50] <ilias_gr> no such channel under freenode
[16:50] <nacc> Younder: krita the painting application? why would it need networking virtual bridged or not
[16:50] <nacc> ilias_gr: yes there is.
[16:50] <blkdrake> Hi I am using Ubuntu 18.04, Hibernate is not working in my laptop, any suggestions on how to make it work?
[16:50] <Younder> I know about bridges, use a few myself, but this seems messy.
[16:51] <ilias_gr> yes you have right.i didn't put # !
[16:51] <nacc> Younder: what are you talking about?? snaps don't use bridges. If you have some virt. stack on your system, it will need a bridge (by default) so that your VMs work.
[16:51] <nacc> ilias_gr: ok :)
[16:52] <ilias_gr> thank you all for your time today and your advises!
[16:53] <TJ-> Unexpected issue on 18.04 - adding a gretap interface also creates an erspan interface, and then "ip link del XXXX" seems to silently fail for each of the erspan/gretap/gre interfaces that were created. Anyone have experience of this or suggestions on what's going on?
[16:53] <Younder> Anyhow it is just going to get messier. And yes, Docker creates a few too.
[16:53] <blkdrake> I followed the procedure given in here, https://ubuntuforums.org/showthread.php?t=2392205 but no luck :(
[16:54] <blkdrake> can somebody help me?
[16:54] <pragmaticenigma> !patience | blkdrake
[16:54] <nacc> Younder: ok, i'm done helping you, as  you don't seem to have an actual support question, and are just ranting. Have a nice day.
[16:54] <TJ-> blkdrake: how is it not working? does it fail to hibernate (with some log entry), or seem to hibernate but not resume to the saved image?
[16:55] <lotus|NUC> blkdrake: a good start to debug is also your syslog or dmesg output, please share it to the channel
[16:55] <blkdrake> TJ-, it seem to hibernate but not resume to the saved image
[16:56] <cluelessperson> printing doesn't work
[16:56] <cluelessperson> sigh
[16:56] <cluelessperson> I print something from chrome, nothing shows up in print queue
[16:57] <TJ-> blkdrake: OK, that's a good start! That suggests 1 of 3 immediate possible issues: 1) a hibernate image was not saved 2) an image was saved but to the wrong RESUME device 3) the image was saved to the correct RESUME device but was truncated/corrupted
[16:57] <nacc> cluelessperson: start with 1) ubuntu version 2) printer model and how its connected 3) does printing a test page work?
[16:59] <TJ-> blkdrake: the most obvious one is the RESUME UUID not being set correctly in the initrd image - you can check that via "cat /etc/initramfs-tools/conf.d/resume" and comparing with the swap partition's UUID via "sudo blkid"
[16:59] <cluelessperson> Ubuntu 18,  printer is connected to a cups print server
[16:59] <nacc> cluelessperson: 18.04? 'cups print server' = a dedicate machine that is just handling printing?
[17:00] <cluelessperson> nacc: basically, yeah.
[17:00] <nacc> cluelessperson: ok, what about question 3?
[17:02] <blkdrake> TJ-, I dont see my swap file in df -h
[17:02] <TJ-> cluelessperson: is the 'default' printer set to something else? In Chrome, do you get the option to choose which printer?
[17:02] <TJ-> blkdrake: "cat /proc/swaps"
[17:04] <blkdrake> TJ-, cat /proc/swaps shows my swapfile
[17:04] <cluelessperson> TJ-: it was some weird ubuntu queuing thing
[17:04] <cluelessperson> I removed the system /etc/cups/client.conf  file and readded the print server in the gui interface
[17:05] <cluelessperson> works now
[17:05] <TJ-> blkdrake: which it should, but I'm not sure why you're telling us that. I indicated previously how to ensure the initrd is using the correct swap device for hibernation
[17:05] <TJ-> cluelessperson: easy solutions are always best :)
[17:06] <cluelessperson> TJ-: I'm just concerned that things break like that without much explanation in ubuntu for me
[17:06] <cluelessperson> I don't mean to bitch, but I can't afford to track down the issue when I'm working
[17:06] <blkdrake> TJ-, the swap file is in another user's /media folder. doing an ls -al tells permission denied. Will that be an reason for the issue?
[17:08] <blkdrake> -rw-r--r-- 1 root root 21474836480 Sep 29 04:10 /media/admin/swapfile.img
[17:08] <TJ-> blkdrake: I'm not sure how the system copes using a swap file for hibernation rather than a partition, it isn't a scenario I've tested. But as for permissions, unless that user's home directory is encrypted, or on a separate file-system that isn't mounted at 'resume' time, then the kernel should have access to it
[17:09] <TJ-> blkdrake: there should be some mention of trying checking the hibernate file in the kernel log
[17:10] <TJ-> blkdrake: /var/log/kern.log should have info on the hibernate 'save image' part starting from a message of the form "PM: Creating hibernation image: ..."
[17:12] <TJ-> blkdrake: sucessful resume is indicated by "PM: hibernation exit"
[17:12] <cluelessperson> TJ-: thanks for your help though
[17:12] <cluelessperson> :)
[17:13] <blkdrake> ok let me check that and come back. thank TJ-
[17:13] <TJ-> blkdrake: on resume you should also see "PM: Starting manual resume from disk"
[17:14] <TJ-> cluelessperson: is it possible the print server changed name/IP address, so that your local client config was then incorrect? If the 'print server' relies on DHCP that could be an issue
[17:14] <TJ-> cluelessperson: print server(s) should be using static (reserved)  DHCP leases or manual IP address configuration
[17:15] <TJ-> cluelessperson: or if addressed via name, it could be ether regular DNS problem, or a temporary failure of multicast-DNS (for which using "avahi-browse -art" is a good diagnostic aid)
[17:17] <cluelessperson> TJ-: no, I just now added the client config and restarted the local cups instance.
[17:17] <cluelessperson> it detected the printer, just printing to it, nothing showed up in the queue
[17:18] <cluelessperson> now that I added it through the gui instead (and removed the client.conf) it shows up in the queue and prints fine.
[17:19] <TJ-> cluelessperson: when you say "it detected the printer" what "it"? Chrome? CUPS admin?
[17:19] <cluelessperson> TJ-: oh sorry,   Chrome and the Ubuntu gui
[17:20] <cluelessperson> When added through the client.conf,  Chrome and Ubuntu GUI showed the printer and allowed me to select it, but the job never seemed to show up in the queue.
[17:20] <TJ-> cluelessperson: if the printer is being advertised by the CUPS print-server using multicast-DNS (avahi) then it could be Chrome/GUI can detect the printer but cannot create the correct config - I know of many network-attached printers whereby they offer several methods of printing, but some wil just silently fail.
[17:21] <cluelessperson> TJ-: I'm able to print to it now, having added it through Ubuntu's GUI instead.
[17:23] <TJ-> cluelessperson: I've had weird issues with both Toshiba and Kyocera network printers in that regard
[17:28] <blkdrake> TJ-, https://pastebin.com/rd8qTbAL this is what I see in kernel logs
[17:30] <cluelessperson> TJ-:   this is a Brother Laser Printer.   I don't think it's the printer.   I should've seen the jobs queue up on the print server queue.
[17:31] <TJ-> blkdrake: right, so that sugggests either a hibernation image wasn't created, or the code in the initrd.img is looking for it in the wrong place. Can you show us "pastebinit <( grep 'PM:' /var/log/kern.log)" ?
[17:32] <TJ-> cluelessperson: indeed, but if the printer is network-attached, there is always the possibility the local CUPS client/daemon is trying to direct-print to it, rather than relay via the 'print server'
[17:32] <TJ-> cluelessperson: /var/log/syslog or /var/log/cups/ might shed some light on it, if you wanted to dig further
[17:35] <blkdrake> TJ-, here it is https://pastebin.com/N6bxX2P4
[17:36] <nacc> cluelessperson: if your printer is network-visible, why do you have a cups server in front of it?
[17:36] <TJ-> blkdrake: no sign of any hibernation there - only suspends. That might be a pointer that hibernation isn't actually being performed
[17:37] <TJ-> nacc: usually for job/queue control, accounting, etc.
[17:38] <nacc> TJ-: sure, just wanted to make sure things weren't being complicated because that's what it took before. 18.04 really improved the printing experience (IMO)
[17:39] <blkdrake> TJ-,  can see this in the log  kernel: [ 4954.855824] PM: hibernation entry
[17:40] <TJ-> blkdrake: right, preceded by "PM: Image not found (code -22)"
[17:43] <TJ-> blkdrake: if you don't see "PM: Creating hibernation image:" then there's no hibernation image being created
[17:46] <blkdrake> ok let me explain my case, my ram size is 16 Gig, initially when  installing ubuntu I gave the swap space as 2 Gig, then I increased the swap size to 20 Gig as root user. The image is in his /media/otheruser/swapfile.img with -rw-r--r--  1 root root 21474836480 Oct  1 22:45 swapfile.img, I and the other user have admin privileges. what might be the possibility for failure, can we do something about it?

[17:48] <cluelessperson> nacc: because the cups server handles the drivers, and I ues it from multiple machines, and etc.
[17:49] <cluelessperson> also it handles document scanning to an archive for later sorting
[17:51] <nacc> cluelessperson: ah ok, so you have a good reason :)
[17:52] <blkdrake> TJ-, can you help me please
[17:52] <TJ-> blkdrake: I suspect the issue is a swap-file rather than swap partition. As I said, I've not tested hibernation with a swap file
[17:53] <cluelessperson> nacc: the only annoying part is that the scanner goes to sleep and breaks the server connection for scanning sometimes
[17:53]  * cluelessperson shrugs
[17:53] <cluelessperson> anyway, gotta go, thanks again
[17:56] <blkdrake> TJ-, can we delete the swap file and create a new swap partition?
[17:58] <nacc> TJ-: maybe https://wiki.debian.org/Hibernation/Hibernate_Without_Swap_Partition ?
[17:58] <TJ-> blkdrake: If you've got space to allocate a 20G partition, sure
[17:59] <nacc> TJ-: and https://help.ubuntu.com/community/SwapFaq says can't be done on swap file, but not sure if that's current
[18:00] <nacc> ah, you need to pass an extra parameter
[18:00] <nacc> resume_offset=
[18:00] <nacc> https://www.kernel.org/doc/Documentation/power/swsusp-and-swap-files.txt
[18:01] <TJ-> nacc: right; the Debian article is quite old and last time I experimented with it was around 2016 too. Not needed it since; S3 sleep is sufficient nowadays
[18:01] <pragmaticenigma> I'm just wonder if Ubuntu can be configured with the swap file option with the swap file in a location other than the default location
[18:01] <nacc> TJ-: yeah, i haven't hibernated a machine in a long time :)
[18:02] <TJ-> nacc: yeah, with swap-files you have to use "swap-offset" to find out where they are in raw sectors from the start of the parent block device, and use that as the resume_offset
[18:03] <R13ose> Hi
[18:03] <TJ-> I'm not sure how swap-offset copes with device-mapper devices, or how many/which file-systems it can cope with
[18:11] <dimitrigraf> hello there
[18:11] <dimitrigraf> can anybody tell me how to change the background of the login screen after locking the screen with super + L
[18:12] <dimitrigraf> ?
[18:14] <dimitrigraf> i changed the color of the background property of lockDialog in /usr/share/gnome-shell/themes/ubuntu.css but it only affects the background color of the login screen when rebooting and login in for the first time
[18:16] <naptastic> I broke my bootloader, so I network-booted the machine with the broken bootloader into a live environment (Xenial server.)
[18:16] <naptastic> I mounted the local / partition under /mnt/src, and to my surprise, /mnt/src/dev is already populated.
[18:17] <DJones> Does anybody have a recommendation for a standalone twitter client? I used to use corebird, but since the twitter api changes and the dropping of support by the developer, I've not found another standalone client that seems to work as well
[18:17] <naptastic> I never mounted it, so I can't unmount it. Is udev doing something sneaky? Can I make it stop?
[18:20] <TJ-> dimitrigraf: I think that's the 'screensaver' you want
[18:21] <TJ-> naptastic: does "mount" indicate that /mnt/src/dev is really mounted? You're not just seeing static entries?
[18:23] <naptastic> TJ-, it's definitely not in `mount` or /proc/mounts, and umounting says it's not mounted. The contents of /mnt/src/dev are definitely device nodes though.
[18:24] <TJ-> naptastic: right, but probably 'static' in the real file-system, not via a devtmpfs on the dev/ node that udev populates
[18:25] <naptastic> TJ-, my plan is to snapshot the whole OS. Should I ignore them, or delete them?
[18:25] <TJ-> naptastic: if the entries in /mnt/src/dev/ exactly match what the live /dev/ shows, than I'd guess that at some point the devtmpfs for the 'real /dev/ was not being mounted before udevd started, so all nodes were created in the real file-system
[18:25] <naptastic> (snapshot via rsync)
[18:26] <TJ-> naptastic: well if doing rsync, always omit /proc/ /sys/ and /dev/ and possibly /tmp/ (check which are tmpfs types)
[18:28] <naptastic> alright... here's hoping this works. Thanks TJ- !
[18:28]  * naptastic wanders off to a meeting...
[18:31] <Younder> I'd say the things woth saving are in /vr /hom and /usr/local  Putting them in separate partitions makes the system more robust (for var from DOS attacks) and fater to back up and easier to restore.  You will need a root password to install home. /roor is nor under the /home dir so it will still work.
[18:32] <blkdrake> Hi, How do I create a swap partition without rebooting via live CD, I have a swap file currently no swap partition
[18:33] <pragmaticenigma> blkdrake: It is not recommended to repartition a drive that is currently live for the running operating syste,
[18:33] <Younder> Do you have a encrypted home dir?
[18:33] <TJ-> Younder: don't forget /etc/ - that's where the system config lives
[18:34] <TJ-> blkdrake: is the system using LVM or only raw partitions?
[18:34] <Younder> TC yes good point (and version control it with ..)
[18:34] <blkdrake> Younder, No encryption
[18:35] <Younder> blkdrake, get knopfig online, boot from it mount the main drive and use the pationing tool
[18:36] <blkdrake> Younder, I dont have a CD or Pendrive at this moment.
[18:37] <Younder> Then boot from memorystrick if your BIOS allows it
[18:37] <blkdrake> TJ-, How do I see that?
[18:38] <blkdrake> Younder, I dont have a memory stick at this moment, neither a Compact disk.
[18:38] <TJ-> blkdrake: well, generally "sudo lsblk" will show you how the block devices and file-systems are organised
[18:39] <pragmaticenigma> Younder: blkdrake asked for something that didn't require booting from a live disk
[18:39] <Younder> Well firts check if your bios can boot from stick. If it does, get one I suggest a 16 Gb as they are not terriby expensive and can be go everywhere
[18:39] <pragmaticenigma> Younder: You're not very good a reading, are you...
[18:41] <Younder> I see, well maybee. But the thing you can't reformat, check or partion a disk that is already mounted.
[18:41] <Younder> Which is one of the reasons such tools exist.
[18:41] <blkdrake> TJ-, Here you go https://pastebin.com/rqckiNwH
[18:42] <Younder> If there is a second disk you can unmount without the system area, and which it is fin to install the swat, then yes you can.
[18:43] <Younder> I use gpated.
[18:43] <Younder> gparted
[18:43] <pragmaticenigma> Younder: You need to stop... follow the conversation and add things that are helpful. Right now you are taking shots in the dark and not paying attention to what has already been said or done.
[18:44] <Younder> You want to install a swap partion or not?
[18:44] <Younder> This is ysually done at install time not as a afterthought
[18:45] <Younder> So desperate measures
[18:45] <TJ-> blkdrake: afraid I have to shoot off; hopefully someone else can help you
[18:47] <blkdrake> ok, TJ- thanks for you help
[18:48] <blkdrake> Younder, I have a swapfile of size 30G at /swapfile location
[18:48] <blkdrake> trying to hibernate from that, its failing
[18:49] <blkdrake> Younder, I follwed steps in https://ubuntuforums.org/showthread.php?t=2392205
[18:49] <Younder> oh that again.
[18:49] <blkdrake> I wanna hibernate to a swapfile instead of a swap partition
[18:49] <blkdrake> can anybody help me with his.
[18:50] <pragmaticenigma> blkdrake: You need to have patience
[18:50] <blkdrake> pragmaticenigma, ok
[18:50] <Younder> I notice it uses cryptswap which is the secure option
[18:50] <pragmaticenigma> blkdrake: Also, as I mentioned earlier. The proper and safest way to do what you desire is to boot from a live disk. Changing the partitions on a live file system can lead to system breakage.

[19:10] <bray90820> There probably isn't a dedicated ubuntu image for macs is there
[19:10] <bray90820> Even unofficially
[19:10] <bray90820> Or should I just use the standard image
[19:11] <pragmaticenigma> bray90820: Depends on the age of the Mac... Most mac produced recently are running Intel chips and can use the regular Ubuntu installer images.
[19:11] <pragmaticenigma> bray90820: If it is a much older Mac, with a PowerPC chip, there are dedicated images for those as well
[19:12] <bray90820> It's an intel mac but I meant that like has all the other stuff in it like wifi divers ad stuff
[19:12] <ioria> colin969, never used that file myself, but not sure you can use it anymore (with gdm3 hooks and etc. etc . on modern ubuntu versions)
[19:13] <pragmaticenigma> bray90820: Most of the components inside a Mac are standard PC parts. And most of the Mac hardware works with the standard images. There are some quirks with bluetooth, which means Apple Magic trackpads and keyboards are known to have issues.
[19:13] <bray90820> Alright
[19:15] <pragmaticenigma> bray90820: There are some links on the main download page to help with installing on Mac as well. See: https://www.ubuntu.com/download/desktop

[19:49] <TwoNotes> My i386 ubuntu server machine (16.04.5) is in upgrade prereq hell.  Can I do a dist-upgrade to 18.04 anyway?
[19:50] <ioria> TwoNotes, what does do-release-upgrade command  report ?
[19:51] <ioria> TwoNotes, and please define 'prereq hell'
[19:52] <TwoNotes> It can not seem to find linux-headers-4.4.0-137-generic
[19:53] <TwoNotes> Also claims "no space on device' when in fact there is 4.3G
[19:53] <ioria> TwoNotes,  sudo apt update && sudo apt full-upgrade
[19:53] <ioria> TwoNotes,  ok
[19:53] <ioria> TwoNotes,  you need to do some houseclenaing
[19:54] <ioria> TwoNotes,  sudo apt autoremove
[19:54] <TwoNotes> Trying to avoid wipe and reinstall.  This is my 'file server' machine
[19:55] <TwoNotes> autoremove fails with "The following packages have unmet dependencies:
[19:55] <TwoNotes>  linux-headers-generic : Depends: linux-headers-4.4.0-137-generic but it is not installable
[19:55] <TwoNotes> "
[19:55] <ioria> TwoNotes,  probably the previous upgarde failed 'cause the lack of space
[19:55] <ioria> *upgrade
[19:55] <TwoNotes> possible

[19:57] <qwebirc95665> hello, i'm looking for a way to easy backup the programms that i installed ( the names of the programs)$
[19:58] <ioria> TwoNotes,  you cannot upgrade to bionic with no space on the device
[19:58] <qwebirc95665> like it safes all my apt installs in a file in my homefolder
[19:59] <TwoNotes> ioria, sounds like a wipe and install than.  The / partition is 19G.. ENough?  /home is separate
[19:59] <ioria> TwoNotes,  sy, have to leave ... but 19g sounds 'small' for whatever
[20:02] <Bashing-om> qwebirc95665: Might be a solution ' dpkg --get-selections '  will dump a list of all packages you have installed.
[20:04] <qwebirc95665> @Bashing-om if i install ABC and DEF is required for that as i install it, but later it isn't (because ABC is now based on XYZ) will DEF be installed again?
[20:07] <Bashing-om> qwebirc95665: Maybe --- in that case of wonder one can look at what the dependencies are ' apt depends <package> ; apt rdepends <package> ' .
[20:18] <frad> hi
[20:19] <frad> im looking for a way to communicate with people who run windows machines, me being linux. I dont own a smartphone, so anything similar to whats app is off the table. What is it out there that could serve my purpose?
[20:21] <Sven_vB> frad, what communication medium would you prefer? probably network, maybe internet? or something more traditional over telephone lines?
[20:22] <frad> internet. I own a regular cell phone, meaning not a smartphone
[20:22] <Sven_vB> also what kinds of messages do you want to tramsit? e.g. just text? images? audio? video? realtime audio/video?
[20:23] <frad> Sven_vB, just audio would be fine for me. But damily members insist they want to see me
[20:24] <Sven_vB> where is the target audience on a scale from "savvy enough to install obscure programs" to "it should really run in their browser"?
[20:25] <frad> hahaha... the second one
[20:25] <frad> sadly
[20:25] <nacc> frad: why isn't google hangouts sufficient if it's person to person?
[20:25] <frad> nacc, because I never heard of it
[20:25] <Sven_vB> frad, now at least you know a lot more facts to include next time you ask, in case we can't find a solution today. ;)
[20:25] <frad> oh, thanks Sven_vB
[20:26] <nacc> frad: i guess you don't use gmail (sorry, that's relatively rare in my network, even if only casually).
[20:26] <frad> no , not gmail
[20:26] <nacc> frad: built-in chat, works in browsers, and you can do video calls
[20:26] <nacc> frad: there are other similar in-browser options
[20:27] <frad> nacc so I should google for 'in-browser audio call'?
[20:27] <nacc> frad: also, whatsapp has a web interface (i don't understand why your phone is relevant in this conversation, beyond not being able to put apps on it, but that's offtopic here anyways). in the context of ubuntu interoperability with windows users, any web-based service probably works (might require third party plugins etc)
[20:28] <frad> nacc, somebody told me I need a smartphone to scan a code
[20:28] <Sven_vB> I think you need a cellular device (could be a modem) to receive an SMS to ensure you give them a real phone number as your account IT.
[20:28] <Sven_vB> *ID
[20:29] <Sven_vB> frad, usually you only need a QR code reader. there are desktop and CLI programs that can do it.
[20:29] <frad> Sven_vB, so I use the interface, but they bill me through my phone
[20:29] <nacc> frad: ah i see that you do.
[20:29] <Sven_vB> oh. if you pay for it, you could just use one of the premium webcam sites and have lots more privacy.
[20:30] <Sven_vB> in theory you could even have *them* pay. ;D
[20:30] <frad> sorry, whatsapp its free because they mine user's data :)
[20:31] <nacc> frad: you asked for options
[20:31] <nacc> frad: you didn't put conditions on them, afaict.
[20:31] <frad> all good na
[20:31] <frad> all good nacc
[20:31] <Sven_vB> oh also I think SMS is called text message in the US.
[20:32] <qwebirc95665> is there a text-based full-crypto no-usefull-meta-data type of chat? (usefull metadata= both user talking to same server or oh 100ms after he sent somthing via tor, he recived something via tor)
[20:33] <qwebirc95665>  like reaaaly secure
[20:33] <Sven_vB> qwebirc95665, if you want better resistance against time correlation than TOR has, you need a relay. you could try hosting a message relay on a TOR hidden service.
[20:34] <Sven_vB> qwebirc95665, the peer should probably do as well, so both of you decide a (different) schedule of when you send how many bytes, and you stick to that, no matter how much message is waiting.
[20:35] <qwebirc95665> hm is there somthing like that allready?
[20:35] <Sven_vB> qwebirc95665, you could even plan a schedule with multiple blogs, when whom of you will comment with what author name on which blog post, and hide the message bits in some aspect of an otherwise insuspicious text.
[20:36] <Sven_vB> qwebirc95665, I've no idea, but the TOR people probably know.
[20:36] <qwebirc95665> that sounds fun
[20:36] <qwebirc95665> its hard to generate insuspicious text
[20:36] <Sven_vB> you could also camouflage as a regular spammer
[20:37] <qwebirc95665> that sounds like a lot of fun
[20:37] <Sven_vB> you could read facebook to get some inspiration about how to create realistic messages even in absence of meaningful input data.
[20:37] <qwebirc95665> xD
[20:38] <Sven_vB> depending on your foes you could also setup a video stream that looks like something people would want to encrypt for privacy, but the obvious content is not the one you care about.
[20:38] <Sven_vB> rather some minutiae about how the video frames are encoded.
[20:39] <bray90820> Should the bootloader be installed on /boot or /
[20:39] <Sven_vB> bray90820, I like to use a separate partition, just for trolling.
[20:40] <Sven_vB> bray90820, if you don't have a good reason for /boot, have your /boot on /.
[20:40] <bray90820> So all I would need is / and swap?
[20:40] <qwebirc95665> . /home comes in handy sometimes
[20:41] <qwebirc95665> like easy backup
[20:41] <Sven_vB> bray90820, swap only if you have a reason for it. hibernation might be one, dunno.
[20:41] <bray90820> I'll just use / and swap
[20:42] <Bashing-om> bray90820: ESP  EFI System Partition ??
[20:42] <bray90820> EFI it's a macbook
[20:43] <qwebirc95665> does you bios support legecy boot without secureboot?
[20:43] <bray90820> No It's a macbook
[20:43]  * Bashing-om runs away :P
[20:43] <bray90820> No bios options
[20:44] <Sven_vB> with Ubuntu 16.04.5 LTS xenial and Xfce 4.12, how can I get a more specific battery display in my task tray? Currently I run the one from /usr/…/xfce4/panel/plugins/libbattery.so but it keeps showing "Charging from AC" even when "acpi -b" already changed from "charging" to "Unknown", which for me means charging has become so slow I don't care about the remaining percents.
[20:46] <frad> do you guys know if there is anything like telegram for smartphones?
[20:47] <qwebirc95665> yes, telegram

[21:29] <kynon> i am trying to run lxd on my ubuntu 18.04 machine but i am getting a weird error when it comes to ZFS
[21:30] <kynon> this is the error: https://i.imgur.com/tS8tZIT.jpg
[21:30] <MaoKo> Bashing-om: ok ty
[21:31] <Bashing-om> MaoKo: :) with the universe repo enabled .. should be able to install by ' sudo apt update ; sudo apt install fbi ' .
[21:33] <kynon> anyone knows why this thing acts out likee this?
[21:34] <nacc> kynon: you are out of /tmp space
[21:35] <kynon> nacc: but how? 6TB HDD and fresh install, loop device is set at 15GB
[21:35] <nacc> kynon: which probably means you are actually out of / space
[21:35] <nacc> kynon: dunno, hard to say, but it's clear that python couldn't create a tempfile at some point
[21:35] <kynon> so what should i do?
[21:35] <nacc> kynon: loop device?
[21:35] <kynon> yeah lxd asks about setting up a loop device
[21:35] <nacc> kynon: probably boot into recovery mode and check your disk usage
[21:36] <nacc> kynon: oh that's probably the snap? not sure. i've not used it yet. you can also ask in #lxcontainers
[21:36] <kynon> nacc: installed from repo unless it uses snap automatically but i did not do it through that way
[21:43] <jadax> hey, I have a terminal only access to Ubuntu 16.04.5 system, how can I configure it to 'always on'? I don't want screen saver / sleep / hybernation at all
[21:44] <nacc> jadax: it's an ubuntu desktop installation? or ubuntu server?
[21:44] <jadax> desktop
[21:45] <nacc> jadax: is there a reason you installed desktop but want 'terminal only' access?
[21:46] <jadax> yes, we run many systems around and they are all 'ubuntu 16.04 desktop' for the purposes of having everything 'the same'
[21:46] <jadax> it starts off the fact that we build chromeOS and 16.04 desktop is their preferred system
[21:46] <jadax> their = google's
[21:47] <nacc> jadax: not sure i follow -- you need a desktop to build chromeos? that doesn't make sense
[21:47] <jadax> why not?
[21:47] <nacc> jadax: desktop and server are the same packages, just different defaults
[21:47] <nacc> jadax: because it's just building something
[21:47] <kynon> nacc: so I am trying to get this installed and I am getting this error: https://hastebin.com/gefexuvida.java
[21:47] <jadax> there is chromeOS build that uses ubuntu 16.04 as preferred system - so we just follow their requirements
[21:47] <kynon> nacc: this is my hdd https://hastebin.com/ucuvahexov.sql
[21:47] <nacc> kynon: uh, line 4 and 5
[21:47] <nacc> kynon: totally invalid networking configuration
[21:48] <nacc> jadax: ubuntu 16.04 != ubuntu 16.04 desktop ... and again, if you are just building, you can run server.
[21:48] <jadax> also, I spent once whole day trying to install server distro behind the proxy; apparently desktop and server installer are different and the server one wouldn't let me inject proxy
[21:48] <kynon> nacc: but this is an upgrade from 16.04 to 18.04
[21:48] <nacc> kynon: what?
[21:48] <nacc> kynon: you entered an invalid value for a prompt
[21:48] <nacc> (i think?)
[21:48] <jadax> so is there some command line tool or configuration file that I could go to and make sure system is 'always on'  /
[21:48] <jadax> ?
[21:49] <nacc> jadax: you can disable power management, i think, /etc/pm/?
[21:49] <nacc> jadax: but tbh, this seems like a totally wrong way to do things, and i stand by that :)
[21:50] <kynon> nacc: valid ip was in ifupdown and then performed an upgrade but it looks like netplan wasn't setup
[21:51] <nacc> kynon: i'm not sure, i thought that case was handled. I don't know where 1/24 came from, but it's obviously incorrect
[21:52] <jadax> I found that on stackexchange: sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
[21:54] <nacc> jadax: that might work, yeah
[22:01] <TJ-> jadax: if the GUI has a user logged in those sleep/suspend issues will likely be controlled directly by the GUI power management tooling. If I recall correctly, they don't call into the init system services
[22:03] <nacc> TJ-: that's a good point, I forgot about that
[22:03] <jadax> TJ- so the only way to reliably make system 'always on' is through GUI?
[22:04] <TJ-> jadax: is a user logged in via GUI when you're connected via ssh ?
[22:05] <TJ-> jadax: If the GUI is only at the greeter log-in, then a possibly different set of conditions apply :)
[22:06] <TJ-> jadax: there are command-line tools that can be used to change the GUI power-management settings - but they have to be run using the account of the GUI  user(s) accounts
[22:09] <jadax> GUI user is not logged in, I can ssh in as GUI user
[22:09] <jadax> the system is at welcome screen
[22:11] <TJ-> jadax: if it's the default Ubuntu install it'll be Unity/Gnome tooling, which means editing the gconf local user 'database'
[22:12] <nacc> jadax: so, tbc, what do you actually use the GUI for? how do you build chromeos on the system? fwiw, i think getting server installed with proxy is way faster than doing down this route (and minimizes the amount of 'junk' on your build system)
[22:13] <TJ-> jadax: this is the tooling you need to use. You'll have to discover the nodes to alter/set elsewhere though. https://askubuntu.com/questions/22313/what-is-dconf-what-is-its-function-and-how-do-i-use-it#191013
[22:14] <TJ-> jadax: if you don't use the GUI at all on those desktop systems, make them into 'servers' by disabling the GUI via "systemctl set-default multi-user.target"
[22:14] <TJ-> jadax: that command boots to a standard, non-GUI, multi-user environment
[22:14] <nacc> TJ-: oh yeah, good point
[22:16] <jadax> nacc I tried once installing 16.04 server on proper 4U server. I wasted all day and achieved nothing. The server installer is different than desktop installer. Also, proper server boots for approx 10min, so every reboot I would have to wait that long. Then nobody on #ubuntu would believe me that there are some problems in installer. I really don't
[22:16] <jadax> want to go back to these memories.
[22:17] <jadax> I don't use GUI for building, you are right, I don't technically need it
[22:17] <nacc> jadax: ok, that's your choice, understood.
[22:18] <TJ-> jadax: when there are boot-time issues, "systemd-analyze critical-path" and "systemd-analyze blame" are your friends
[22:37] <pikia> is it possible to have a program or script constantly watch a directory and on a file change, upload the entire directory via sftp to a remote server?
[22:40] <hggdh> pikia: yes, and this type of program/script is usually called a directory watcher/monitor
[22:41] <pikia> Ahh ty ty
[22:41] <TJ-> pikia: you can use the inotify-* tools for that
[22:41] <pikia> NIce, I'm glad to see tools were made for this problem already haha
[22:42] <TJ-> !info inotify-tools | pikia use "inotifywait" in scripts
[23:18] <shazbotmcnasty> Hey there. I've been trying to figure out for days why I can't shut down this computer with the normal shutdown or restart commands. I've tried all of the grub changes that I've been suggested. Updated fully including the xenial-proposed looking for a fix with no end change. This is an old Dell Inspiron 1501 laptop. Anyone have any suggestions?
[23:20] <shazbotmcnasty> When removing "splash quiet" from grub, I can see where it hangs. It's not on anything in particular, instead just "reached target shutdown"
[23:21] <cheater> not an educated guess, but i would say your computer is failing to change the power state
[23:21] <cheater> so check if your uefi allows that and if you have the right drivers
[23:21] <cheater> and maybe your power supply is at fault
[23:22] <shazbotmcnasty> this computer doesn't have uefi
[23:22] <shazbotmcnasty> there are no available drivers in teh 'additional drivers' utility.
[23:22] <shazbotmcnasty> though I could probably find some <_<
