[00:02] <ExcessiveAggro> evening
[00:10] <jayjo> is there a wiki page or some other recommendation for single disk boot partitions using uefi with LVM?
[00:11] <jayjo> using gpt
[00:17] <jayjo> do I only need a single 512M EFI partition, and the rest is my single LVM partition?

[01:42] <swarmachines> hi
[03:02] <jwash> I'd appreciate any ideas about how to block youtube on my network for all computers except for 1 or two explicit IPs.
[03:28] <leftyfb> jwash: Is your router running Ubuntu?
[04:00] <jwash> leftyfb: DD-WRT
[04:00] <jwash> I've been feelling like it's time to move away from my router to a computer to do the routing
[04:01] <derpadmin> I do it, so far so good
[04:01] <leftyfb> jwash: I would look into ubiquiti. But none of this is on topic for this channel. Try #networking or #ububtu-offtopic
[04:22] <crabs> Anyone had luck on installing Ubunto on the Alix 2D13 single board computer? https://wiki.polaire.nl/doku.php?id=debian_buster_alix2d13 works for me for Debian...
[04:22] <crabs> Ubuntu*

[06:33] <Xeroine> Hello, I'm trying to install IceWM on Ubuntu from a tar file using the instructions from their website but when I do "./configure --prefix=/usr" I get the error "configure: error: Packages SM and ICE are required for session mgmt.". Does anyone know how I can install those two packages? I couldn't find their names
[06:36] <CorruptByte> Did you run the script that installs all of the dependencies?
[06:36] <CorruptByte> Xeroine: See above
[06:37] <Xeroine> wdym, what script is that?
[06:38] <Xeroine> I thought the configure script does that
[06:38] <CorruptByte> Look for heading Install package dependencies on the ice-wm.org homepage
[06:38] <Xeroine> alright
[06:38] <Xeroine> oh
[06:39] <Xeroine> thanks a lot, should've read the entire thing
[06:39] <CorruptByte> No worries :)
[08:59] <conjo> hey all-how would i change font font size and window coloum and row settings for my terminal(bsh ubuntu 20.04.1 (really want to learn how to do this via configs file adjustment, i know how to do it via gui)
[08:59] <conjo> eg what file am i looking for
[08:59] <Mr_x> hi
[08:59] <conjo> =)
[09:00] <Mr_x> anyone ever face this error :
[09:00] <Mr_x> error: could not create '/usr/local/lib/python3.7/site-packages/antlr4': Permission denied
[09:00] <Mr_x> this occur when try to run --->> python3 -m pip install -r requirements.txt
[09:01] <Mr_x> I'm a bit confused .. do I need to use "--user"? , and is that a good option .. or is there another better way?
[09:02] <ducasse> Mr_x: try with --user, as without it is a system install
[09:02] <TJ-> Mr_x: presumably your user doesn't have write permissions to /usr/local/lib/ - maybe execute the command using "sudo ..."
[09:02] <ducasse> conjo: which terminal are you using?
[09:03] <conjo> bsh
[09:03] <conjo> i assume ubuntu ships with default bsh ill check
[09:04] <Mr_x> ducasse, that is the good way for that?
[09:04] <conjo> GNOME Shell 3.36.4
[09:04] <Mr_x> TJ how to give permission to user for /usr/local/lib/
[09:04] <ducasse> conjo: never used that before, but look under ~/.config
[09:05] <TJ-> Mr_x: if possible try ducasse's suggestion first
[09:05] <Mr_x> TJ- how to give permission to user for /usr/local/lib/
[09:05] <TJ-> Mr_x: otherwise prefix commands with "sudo " to elevate privileges
[09:05] <conjo> ty
[09:06] <conjo> what do you use?
[09:06] <ducasse> Mr_x: i would generally install to a user directory before doing a system install with pip
[09:06] <ducasse> conjo: i don't deal with java, for terminal emulator i use roxterm and urxvt
[09:07] <Mr_x> ducasse, can u give suggestion the correct command with "--user"
[09:07] <Mr_x> i already read docomentation but still confuse
[09:08] <Hamidreza> Hi, I'm not understanding why when we want to ssh to a server without password , we should copy our public key to that server !!! I thought that we should have the remote server private key, How would it work?!
[09:08] <ducasse> Mr_x: you should just need to add --user to the command line
[09:08] <Hamidreza> why we dont copy the remote server private key to our server?!
[09:09] <ducasse> Hamidreza: the private key is not shared, it's private :)
[09:09] <Mr_x> ducasse, like this correct ---->> python3 -m pip install --user -r requirements.txt
[09:09] <Hamidreza> ducasse, How would it work?
[09:09] <Hamidreza> what is the structure behind it?
[09:10] <Hamidreza> you have my public key so I can ssh to you without password?!!!
[09:10] <Hamidreza> its wierd!
[09:10] <ducasse> Hamidreza: the private key on the host your ssh'ing from is authenticated against the public key on the host you're ssh'ing into
[09:10] <Mr_x> ducasse, i mean where to put "--user" on that command
[09:10] <Mr_x> :D
[09:10] <conjo> ducasse, this all i see in that dir any suggestions configstore?
[09:10] <conjo> https://pastebin.ubuntu.com/p/XYDH8T4swW/
[09:10] <ducasse> Hamidreza: look into public key cryptography
[09:11] <Hamidreza> ducasse, I confused
[09:11] <Hamidreza> can You explaned it more
[09:11] <Hamidreza> or give me a link please
[09:11] <conjo> watch a video on youtube
[09:12] <ducasse> Hamidreza: https://en.wikipedia.org/wiki/Public-key_cryptography
[09:12] <rory> Hamidreza, if the same key was used to authenticate as was copied to the server, then anyone with access to the server can get access to the private key
[09:12] <Amaranth> Hamidreza: You can encrypt things with the public key that only the private key can decrypt. The server encrypts a challenge message and send it to the client, if the client has the matching private key it can decrypt and give the correct response
[09:12] <rory> Hamidreza, that would be bad, because the private key is probably used to access lots of servers
[09:13] <rory> Hamidreza, you can safely put your public key on a website and the worst people can do is let you log into their servers :)
[09:14] <conjo> Hamidreza,
[09:14] <conjo> Hamidreza, https://www.youtube.com/watch?v=GSIDS_lvRv4
[09:15] <ducasse> conjo: i don't see a way to configure it from reading the man page, if you install bsh-doc you will get the docs in /usr/share/doc/bsh-doc/
[09:15] <conjo> ty man
[09:16] <Amaranth> https://www.digitalocean.com/community/tutorials/understanding-the-ssh-encryption-and-connection-process#authenticating-the-user-39-s-access-to-the-server
[09:17] <conjo> what where some of you're google search strings ducasse i didnt find anything but was at a loss for what to search for (succinct and accurate)
[09:18] <conjo> ducasse, eg my search terms where verbose, and perhaps not even the right terminology
[09:18] <ducasse> conjo: i just installed the package and read the man page :)
[09:19] <conjo> lol i feel dumb
[09:19] <conjo> ty man
[09:19] <conjo> rolf i must just rtfm
[09:19] <ducasse> conjo: don't, it's all a learning experience :)
[09:21] <conjo> ;)
[09:28] <ducasse> conjo: if it is your terminal you want to configure, however, that is an entirely different issue
[10:33] <Hamidreza> Amaranth, I understand what is priv and pub key and why we share our public, because private is private and just we should have it
[10:33] <halvors> I'm trying to launch a container with unshare()
[10:33] <Hamidreza> but
[10:34] <halvors> First with busybox which works fine, but launching a daemon in the background does not work as process 1 exits when the daemon forks.
[10:34] <halvors> Any way to workaround that?
[10:35] <Hamidreza> the remote accept our public key and when we want to ssh to server it see that it can decrypt it with pub, so it understand this is me and let me in
[10:35] <Hamidreza> but How it will encrypt my data?
[10:36] <Hamidreza> because if I encrypt my data via priv all body can see the content because the can decrypt with pub
[10:38] <locsmif_work> How can I check what the latest binary nvidia driver is? If I google around, they just seem to 'know' the package name to provide to apt, which has an incrementing number in it. How do they know the number?
[10:47] <oerheks> ubuntu-drivers list # would show available driver numbers?
[10:47] <oerheks> -340 and so on
[10:55] <locsmif_work> oerheks: that lists older ones
[10:56] <oerheks> those are the official tested ones, there is a ppa with more drivers, https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa
[10:56] <oerheks> but why do you need a newer one?
[11:06] <ducasse> Hamidreza: anyone can encrypt data against your public key, but only your private key can decrypt it
[11:17] <locsmif_work> oerheks, I didn't see I needed a newer one
[11:17] <locsmif_work> say*
[11:18] <locsmif_work> Just want a proper way to check what the newest one is
[11:20] <ducasse> locsmif_work: 'apt list nvidia-driver*' should work
[11:21] <TJ-> locsmif_work: do you mean, the latest version Nvidia publish, or the latest available in a particular Ubuntu release?
[11:43] <amirouche> hello, I updated my box this morning and restarted it, and now my lxc containers can ping the host, but can not ping the internet.
[11:46] <amirouche> I will reboot...
[11:50] <WaV> I know they're gone, but I had a similar issue with IPV6 addresses (Possible upgrade related bug?). I temporarily disabled IPV6 until I cared enough to look into it.
[11:58] <tilerendering> hola
[11:58] <lotuspsychje> welcome tilerendering
[12:04] <locsmif_work> ducasse: thanks
[12:04] <locsmif_work> TJ-: both, I guess, but for the newest nvidia, I suppose I can visit their website
[12:17] <amirouche> after reboot everything works as expected, it is probably due to me fiddling with systemctl
[12:20] <tete_> i have a webcam (logitech) and it works for pictures but it also has a mic integrated and somehow its not possible to use that. i used https://www.onlinemictest.com/ for testing and https://www.onlinemictest.com/de/webcam-testen/ for video
[12:21] <tete_> guess i found the problem, it was deactivated in pavucontrol ;)
[12:36] <arseru> Hi! How is your system python setup? Do you people have a 'python' binary still pointing to python2.7 and 'python3' pointing to python3.X? I have ubuntu 20.04 and I don't have a 'python' binary, and I was wondering if that is correct or I should fix it
[12:40] <Elliria> Hey there, the https://ubuntu.com/tutorials/install-ubuntu-on-chromebook#3-installing-ubuntu-with-crouton page has a link near the top for downloading Crouton. It's a shortened Google link and I'm trying to find out where it takes you. Those goo.gl links are now deprecated, so you can't use the Google site to find out. Does anyone have the actual link to Crouton?
[12:42] <Elliria> I've also been to Crouton's GitHub page and even they use those shortened Google links and don't give away their URL.
[12:43] <oerheks> type crouton in bing?
[12:43] <oerheks> not sure why you dislike google?
[12:43] <Elliria> It's a shortened link and doesn't tell me where it's taking me. I never click such things. I always check where they go.
[12:43] <lotuspsychje> didnt ubuntu picked up on chrmbooks these days without crouton?
[12:44] <oerheks> Elliria, no  clue either.
[12:44] <Elliria> Someone has a Chromebook and wants to install Linux and Crouton looks like the best way.
[12:44] <Elliria> I've been searching for a while now and it's a bit rough, because you have to word your searches carefully or you'll get food results instead of that specific Crouton app's information.
[12:45] <oerheks> show real url; https://urlex.org/
[12:47] <Elliria> Thanks, but that fails a scan as a phishing site. I appreciate the effort, though.
[12:48]  * oerheks puts on a tin foil hat
[12:49] <ExcessiveAggro> :)
[12:51] <ExcessiveAggro> dang Elliria just left - i was going to provide the links
[12:52] <ExcessiveAggro> In case he/she comes back - https://github.com/dnschneid/crouton
[12:58] <ExcessiveAggro> Oerheks is this the main place people come for ubuntu support?  What is the most common support avenue? I like helping - helps me learn more :)
[12:58] <oerheks> This is the main support channel, yes.
[12:58] <ducasse> ExcessiveAggro: there's the ubuntu forums and askubbuntu as well
[12:59] <oerheks> also there is #kubuntu #xubuntu and more
[12:59] <ExcessiveAggro> I might go check out the forums to see what i can do
[12:59] <ExcessiveAggro> I probably need to change my handle... people think I'm about to yell at them.

[13:35] <Hamidreza> Hi guys, Is there any tuning for sysctl in ubuntu 20?
[13:36] <Hamidreza> I have this tuning for ubuntu 16.04 but I want this for ubuntu 20
[13:47] <lotuspsychje> Hamidreza: tuning?
[13:47] <Hamidreza> yeah
[13:47] <lotuspsychje> Hamidreza: a systemd manager, is that what you need?
[13:48] <Hamidreza> things like nofile
[13:48] <Hamidreza> hard or soft in /etc/security/limits.conf
[13:49] <Hamidreza> or sample about sysctl.conf
[13:50] <oerheks> things changed with systemd.
[14:33] <pizzaburger> Hello! I might be having some issues with temperatures. Using sensors command, idle CPU temp ~44C, but once I start something light like a Twitch stream or a video it jumps to ~70C. Dell XPS13 i7-8550U, running Ubuntu 20.10.
[14:34] <pizzaburger> Could any one please help me figure out what's wrong here?
[14:36] <v0lksman> kinda normal...?
[14:36] <v0lksman> video isn't "light"
[14:37] <v0lksman> but if you think that the heat is really an issue you can check the fan and make sure it isn't cluttered with dust, good ventilation through your case etc...last resort would be to ensure that the thermal paste between your CPU and fan/heat sink is evenly spread and doing it's job
[14:38] <pizzaburger> 70C is normal? The fan is going crazy too. Well the issue here is that it's a laptop
[14:40] <v0lksman> https://www.google.com/search?q=xps13+i7-8550u+optimal+temperature&oq=XPS13+i7-8550U+optimal+temp&aqs=chrome.1.69i57j33i21.4440j1j7&sourceid=chrome&ie=UTF-8
[14:40] <v0lksman> quite a few mentions that that CPU runs hot
[14:45] <pizzaburger> RIght. Well the issue I'm having is that I use a Dell USB-C hub to connect an external Dell monitor via DMIH, ethernet cable, USB mouse. The actual hub doesn't have charging capabilities, yet it still gets warm which shouldn't happen. quite regularly the hub just shuts down.
[14:47] <pizzaburger> MOREOVER, haha, the 3,5mm jack has started emmiting a static noise whenever I connect external speakers and when no sound is being played.
[14:48] <pizzaburger> So I;m pretty much having a plethora of these issues and have no idea where to start. Thought maybe the temps were responsible.
[14:49] <v0lksman> sounds like a bad hub to me
[14:50] <pizzaburger> Okay, will try taking it to an eletrician
[14:50] <pizzaburger> How do I approach the 3.5mm jack issue?
[14:50] <v0lksman> sorry was the jack not on the hub?
[14:50] <pizzaburger> No, laptopt jack
[14:50] <leftyfb> pizzaburger: an electrician isn't going to be able to help you with a piece of electronics
[14:51] <pizzaburger> The strange thing is that when I have a Whonix GW/WS open, that static noise disappears
[14:52] <pizzaburger> leftyfb: You're right. Well to a person which fixes electronics. Electrical engineer?
[14:57] <leftyfb> pizzaburger: does it still make the noise if you reboot and just sit at the BIOS screen?
[14:58] <pizzaburger> lemme check
[15:00] <pizzaburger> Brb, have to reboot
[15:05] <pizzaburger> v0lksman, so no static noise on BIOS screens. As soon as the LUKS FDE window appears for decryption before Ubuntu boot, the static starts.
[15:06] <pizzaburger> Also, if there's any sound being played the static stops
[15:24] <pizzaburger> Back
[15:45] <nbusrone> How do I set unzip files set to ram  ? Using SSD. Open a zip pdf file without extract which is 100mb but ubuntu cache it at ./cache/abced .I am using a SSD , wouldn't it cause more r/w to the SSD ?
[15:46] <nbusrone> if the file is 500mb , ubuntu will put the file into cache which take up SSD burden and increase write to system which prolong ssd life with lesser r/w ?
[15:47] <oerheks> r/w to ssd.. white spots damage are a long time ago
[15:48] <oerheks> and that would require writing to the same sector over and over again...
[15:48] <oerheks> so, no worries, nbusrone
[15:49] <nbusrone> oerheks : oh , the first day i use ubuntu on ssd , it wouldn't mind but long after using , i feel like file that always write to SSD may inflect of SSD lifespan
[15:50] <oerheks> that was certainly the case, 10 years ago.
[15:51] <nbusrone> oerheks : what do you mean by certain case 10 years ago ?
[15:51] <nbusrone> oerheks : but somehow , I think ubuntu should have an option to extract the file to memory first. If a user fill up 70% of 250GB SSD , this will be larger impact of lifespan
[15:52] <ExcessiveAggro> nbusrone: I think what he is saying - is that SSD lifespan in the scenarios you are describing are no longer something people worry about.  The lifespan difference is negligible
[15:53] <oerheks> that 70% is not correct, it is more like 90-95%
[15:53] <oerheks> then things slow down
[15:54] <nbusrone> oerheks : hm.. but what i heard was 70% , maybe some test refers to windows.
[15:55] <nbusrone> oerheks : Then , i shouldn't worry on r/w on ssd ?
[15:56] <oerheks> i would not worry indeed
[16:03] <nbusrone> oerheks : how do we count SSD total written on ubuntu ?
[16:04] <nbusrone> oerheks : I install gsmartcontrol shows total written  Logical Sectors Written is around 1260000000
[16:09] <nbusrone> oerheks : since SSD now TLC not MLC
[16:13] <newlinux^> Hi how can I use proxychain for a specific app and not all over the system?
[16:37] <routebee> newlinux^, I don't know exactly but a work around might be to use proxychains on a virtual machine and then you could run apps on the host without it

[17:07] <qbd> hello, i have a problem with cloud-init, do i ask here on in the cloud-init channel ? its regarding not being able to connect with my user defined public key
[17:39] <jayjo> When using UEFI booting, is there a reason to have a separate /boot partition? In addition to the EFI system partition at the beginning of the disk?
[17:41] <jayjo> I'm inspecting an installation after letting the installer automatically partition a disk with LVM, and referencing tutorials and documentation. e.g. https://linuxtutorials.net/install-ubuntu-18-10-server-with-custom-partition-layout-using-lvm-on-uefi-systems/ says to use a /boot partition in addition to the EFI system partition.
[17:41] <jayjo> it says the EFI partition should be 512MB at the beginning of the disk, and then a 1GB /boot partition should also be mounted
[17:42] <jayjo> but Ubuntu's automatic installation with LVM just seemed to use a 512MB EFI partition, and the rest of the disk is partitioned for LVM
[17:47] <jayjo> Is there any benefit to also having /boot a separate partition if ubuntu uses the efi system partition and mounts it at /boot/efi ?
[17:52] <ExcessiveAggro> jayjo: I'm not an expert here but the topic interests me.
[17:52] <ExcessiveAggro> I can think of some reasons but nothing that I seem to care about lol
[17:52] <plushtrap> bruh
[17:53] <ExcessiveAggro> Having separate partitions means you could use a different disk with different performance and/or reliability
[17:53] <ExcessiveAggro> but for those partitions i would imagine you would always want to have decent reliability and performance is not important given then only get utilzed at boot
[17:54] <ExcessiveAggro> So I'm trying to think of a situation when those would matter... thoughts?
[17:54] <ExcessiveAggro> plushtrap: reread my comment and I can see where that would seem jerky without my follow-up messages. whoops didn't mean for it to sound that way
[18:00] <ExcessiveAggro> jayjo: you still there?  I looked around a bit and it looks like only grub and the kernels are stored there.  If that's the case I still can't think of a reason you need it on a different disk
[18:04] <jayjo> I am actually in the case of a single disk right now. But I'm using LVM, so I'm trying to determine if I should partition a /boot at the LVM level, or if there is some reason to have it external to LVM on the single disk
[18:06] <leftyfb> jayjo: only if you want the volume encrypted
[18:06] <TJ-> jayjo: /boot/ is for flexibility and separation of interests
[18:07] <TJ-> jayjo: e.g. I can use a common /boot/ file-system and have multiple root file-systems with different releases
[18:08] <TJ-> jayjo: for LUKS encryption with GRUB_ENABLE_CRYPTODISK=y it also means unlocking /boot/ FS is separate from unlocking root-fs
[18:09] <leftyfb> TJ-: right, but then you need to type the passphrase for each partition.... pain in the neck :)
[18:09] <TJ-> what's this 'type' ?
[18:09] <leftyfb> TJ-: not everyone has an auth device

[18:41] <plushtrap> bye
[18:41] <jess> everything ok?
[18:42] <plushtrap> no u are going to kick and banned me like u did on freenode
[18:42] <phillipsjk> so I want to use the default terminator color theme (ambience) for xterm, but I am having trouble finding the colour table.
[18:42] <octav1a> I'm trying to figure out why load is so high for a program I'm running. It's 100% of one CPU, nearly 0% IOwait, 300gb of free RAM, and running very slow. What else causes load? (I'm getting a load of ~200!)
[18:42] <octav1a> oh!
[18:43] <paniash> plushtrap: I was kidding at the time, looks like you didn't get the joke
[18:43]  * octav1a also pets jess
[18:43] <jess> :3
[18:43] <phillipsjk> octav1a, what is the program doing? That may be expected.
[18:43] <octav1a> It's a scientific program, in the process of writing out some numpy arrays
[18:44] <octav1a> I don't understand why 100% on one core could generate so much more than 1.0 for load.
[18:47] <phillipsjk> The load average tells you how many tasks want to use the CPU. saw something similar for compilitg something: initially the load spiked, but only 6 threads (matching number of cores) were actually running at the same time.
[18:47] <octav1a> I've been monitoring this for days of running and the average remains very high.
[18:48]  * phillipsjk has no idea beyond what he said.
[18:50]  * phillipsjk points to #ubuntu-offtopic 
[18:55] <octav1a> phillipsjk: you were referring to me?
[19:22] <pyeverything> how should i fix "Error: Can't open display: desktop:0"? I am using a local machine (Ubuntu 20.04)
[19:28] <sarnold> pyeverything: how are you trying to start those X clients?
[20:06] <pyeverything> why is Error: Can't open display: desktop:0 error happening in local machine when I call xclock and how can I fix it in Ubuntu 20.04?
[20:10] <sarnold> pyeverything: are you using ssh? how many computers are involved?
[20:11] <pyeverything> sarnold: no I am not using ssh
[20:11] <sarnold> pyeverything: are you using sudo or su or similar?
[20:11] <pyeverything> only one local machine which is a laptop sarnold
[20:11] <pyeverything> it doesn't work with sudo as well
[20:13] <sarnold> pyeverything: oh! doh. sorry. I'm just about a decade behind the times.
[20:13] <sarnold> pyeverything: try DISPLAY=:0 xclock
[20:13] <rustytaco> I'm trying to solve an annoying problem i have, maybe one of you can help? I have a program (dsd) which processes an audio stream containing digital audio and outputs decoded audio. I pipe it to oggeng and then ezstream for remote listening, but oggenc exits when dsd is idle (Not outputting anything) I need to pad the audio stream with silence somehow
[20:14] <pyeverything> I already have tried it and it doesn't work sarnold
[20:14] <sarnold> pyeverything: really?? that's very curious :/
[20:14] <pyeverything> sarnold:  please check here https://unix.stackexchange.com/questions/630957/xhost-unable-to-open-display-desktop0
[20:17] <sarnold> Invalid MIT-MAGIC-COOKIE-1 keyError: Can't open display: :0
[20:17] <sarnold> good good, then that's progress.
[20:17] <sarnold> pyeverything: set the XAUTHORITY variable to point to your Xauthority file, wherever your X startup routines have stored it
[20:25] <pyeverything> sarnold: how do I do this?  set the XAUTHORITY variable to point to your Xauthority file, wherever your X startup routines have stored it
[20:26] <pyeverything> this is not my realm and I have no idea how to do it. I just want to get rid of this bug to continue my work! sarnold
[20:26] <sarnold> pyeverything: something like XAUTHORITY=/home/sarnold/.Xauthority -- first, find where your X authority file is stored
[20:33] <pyeverything> sarnold: ls: cannot access '/home/mona/.Xauthority': No such file or directory
[20:33] <pyeverything> so I don't have a Xauthority file
[20:36] <sarnold> pyeverything: your login sequence may store it somewhere else
[20:36] <jwash> My network is 75% ubuntu 25% centos. I'm experiencing very poor network performance at random times. I think I have one computer that is the culprit. What are some strategies to track it down. 11 computers total.
[20:36] <pyeverything> how can i figure where it is stored? sarnold
[20:37] <pyeverything> $ fd Xauthority /
[20:37] <pyeverything> /run/user/1000/gdm/Xauthority-l
[20:37] <pyeverything> /run/user/1000/gdm/Xauthority-c
[20:37] <pyeverything> /run/user/1000/gdm/Xauthority
[20:37] <sarnold> pyeverything: yay! try each one in turn
[20:37] <pyeverything> $ cat /run/user/1000/gdm/Xauthority
[20:37] <pyeverything> gokuMIT-MAGIC-COOKIE-1R��9��s{�H��H�l��gokuMIT-MAGIC-COOKIE-1R��9��s{�H��H�l22377/31772MB
[20:37] <pyeverything> why are these like so sarnold
[20:38] <sarnold> pyeverything: you should protect these tokens better :) they're how connections to your X server are authorized, they should be kept secret
[20:39] <pyeverything> are these supposedly private tokens by xauth? since I cannot read them sarnold
[20:39] <jwash> pyeverything: sudo doesn't work?
[20:39] <sarnold> pyeverything: they should be readable *only* by uid 1000
[20:40] <sarnold> pyeverything: if you're not uid 1000 then perhaps you need to keep looking to find your xauthority cookies
[20:40] <jwash> i suspect a driver reinstall could fix it if you haven't done it yet
[20:41] <pyeverything> sudo what? jwash
[20:41] <pyeverything> how do i know if I am uid 1000? sarnold
[20:41] <jwash> can you sudo?
[20:41] <sarnold> pyeverything: run 'id'
[20:41] <pyeverything> sudo to what? for what command? jwash
[20:42] <phillipsjk> octav1a, not, plushtrap
[20:42] <pyeverything> uid=1000(mona) gid=1000(mona) groups=1000(mona),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),120(lpadmin),131(lxd),132(sambashare) sarnold
[20:42] <jwash> to reinstall the graphics driver
[20:42] <jwash> takes 2 or 3 min
[20:42] <octav1a> phillipsjk: okay
[20:42] <sarnold> jwash: X authentication cookies are entirely unrelated to graphics drivers
[20:43] <sarnold> pyeverything: wait a second.. what *exactly* do you mean by "I cannot read them" -- you pasted their contents here, right?
[20:43] <ntz> hello
[20:44] <pyeverything> I meant I cannot make sense of these weird characters ��9��s{�H��H�l��
[20:44] <pyeverything> sarnold:
[20:44] <pyeverything> anyways
[20:44] <pyeverything> how can I solve the actual problem now? https://unix.stackexchange.com/questions/630957/xhost-unable-to-open-display-desktop0
[20:45] <pyeverything> jwash graphic driver has no problem is running properly https://pastebin.com/raw/CmBLAXp9
[20:45] <phillipsjk> octav1a, I think I figured out how you can get a load average of 200 with only 100% CPU ussage: program spawns many subprocesses that all complete in 5ms on average. You should be able to verify this with changing PIDs in 'top' or similar.
[20:45] <ntz> I need little help with one thing .. I am not familiar with this .. helping to friend of mine who is not geek .. he wanted encrypted folder or volume .. I've created for him a file that is LUKS encrypted and could be mounted like virtual disk but I cannot find what to do that if he clicks on the file, the system will attempt to mount it like if it's usb ..
[20:45] <ntz> now the file has suffix .img
[20:45] <pyeverything> and yes I can sudo
[20:46] <octav1a> phillipsjk: that's.....extremely strange
[20:46] <octav1a> But I will look into that possibility.
[20:46] <ntz> # file encrypted_drive.img
[20:46] <ntz> encrypted_drive.img: LUKS encrypted file, ver 1 [aes, xts-plain64, sha256] UUID: 413412f2-79b4-4c55-9dca-ca5581a47a4a
[20:46] <ntz> it can be just mounted, contains one ext4 partition after doing luksOpen ..
[20:47] <EriC^^> ntz: maybe write a script that mounts it and stuff, and you could make a .desktop file for that, so he just double clicks and it does everything
[20:47] <summonner> pyeverything, did you netcat your xrandr output?  eg.     xrandr | nc termbin.com 9999
[20:48] <ntz> EriC^^: ok, yeah, something like that ... must be "bulletproof" because my frind is everything but not a geek nor interested in computers in real
[20:48] <phillipsjk> octav1a, running the root process "niced" may fix the responsiveness issue.
[20:48] <ntz> I was interested if I can do it somehow smartly ... if I have in KDE a file with suffix .img, kde just offers me to mount it .. but not ubuntu
[20:49] <pyeverything> I can't since I get an error Invalid MIT-MAGIC-COOKIE-1 keyCan't open display :0 summonner
[20:49] <sarnold> pyeverything: have you tried *all three* of those Xauthority cookies with your XAUTHORITY environment variable?
[20:50] <summonner> pyeverything, xrandr gives you that specific error?
[20:50] <sarnold> pyeverything: you can't understand what those cookies say because they are similar in nature to ssh keys
[20:50] <pyeverything> yes summonner
[20:51] <EriC^^> ntz: maybe its the kde file manager or some other program that's doing it that covers those files as default
[20:51] <ntz> EriC^^: https://infophagia.com/ntz/paste/c7981a214585f0c7084104afe2be46e2.txt
[20:51] <ntz> ^^ if you wish to test it, here are commands to create a virtual drive
[20:53] <summonner> pyeverything, sorry to ask a question you might have answered before, but you're LOCAL to the machine, right? you've logged in with the desktop? or you're trying to spawn gdm or something?
[20:53] <pyeverything> sarnold:  yes I tried all three the other two were empty please check the updated post here to see results of id and everything else you asked https://unix.stackexchange.com/questions/630957/xhost-unable-to-open-display-desktop0
[20:53] <pyeverything> summonner: please check https://unix.stackexchange.com/questions/630957/xhost-unable-to-open-display-desktop0 and read the first line
[20:56] <sarnold> pyeverything: none of those code blocks show you setting the XAUTHORITY environment variable to the name of each of your Xauthority files
[20:57] <EriC^^> ntz: works fine here on ubuntu 16.04 (unity/nautlius)
[20:57] <ntz> that it automatically opens the device ?
[20:57] <EriC^^> ntz: if i go to properties -> open with, it's set to open with disk mount manager
[20:57] <EriC^^> yes
[20:57] <ntz> ok, cool, thanks
[20:57] <EriC^^> sorry "Disk Image Mounter"
[20:57] <pyeverything> check the 7th code block sarnold
[20:57] <ntz> great, thanks ... lemme check
[20:58] <pyeverything> actually I wrote it in the comments
[20:58] <pyeverything> it didn't work anyways
[20:58] <sarnold> pyeverything: I searched in the page for XAUTHORITY and *none* of the codeblocks show anythiung like: XAUTHORITY=/run/user/1000/gdm/Xauthority xclock
[20:59] <pyeverything> now it's the 8th code block in the original post
[20:59] <pyeverything> please check again sarnold
[20:59] <pyeverything> did you see it sarnold?
[21:01] <sarnold> pyeverything: aha now it's there
[21:01] <sarnold> pyeverything: dang. double-check the timestamp on the file and make sure it matches when you started X? or maybe, restart X, and make sure it gets updated?
[21:06] <pyeverything> sarnold: should I use this command? sudo systemctl restart display-manager I am asking since I am a researcher not a sys admin
[21:10] <shinobi> My wifi keeps dropping and sometimes asks me to reenter the password. This mostly happens when I am away and the screen locks. This does not happen when I boot to windows. Does anybody have any ideas on why this happens?
[21:10] <pyeverything> sarnold: please check update 2 here https://unix.stackexchange.com/questions/630957/xhost-unable-to-open-display-desktop0 (in the beginning of question)
[21:10] <Mr_x> hye
[21:11] <Mr_x> anyone here know how to make cronjob/crontab for sumthing run on tmux
[21:12] <Mr_x> for example on tmux run bot used command ./mybot.py
[21:12] <sarnold> pyeverything: okay, that's promising; can you run xclock now?
[21:13] <pyeverything> no I cannot sarnold
[21:13] <sarnold> dang :(
[21:19] <shinobi> Can someone put this in english: Direct firmware load for iwlwifi-cc-a0-56.ucode failed with error -2
[21:19] <sarnold> shinobi: errno -2 is no such file or directory
[21:20] <shinobi> sarnold: How do I go about troubleshooting this?
[21:22] <sarnold> shinobi: oh man :/ I don't even see that firmware in the upstream firmware collection https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/
[21:22] <sarnold> shinobi: I wonder if this means intel hasn't published it yet?
[21:23] <shinobi> It works kinda. It keeps dropping wifi connection and I manually have to connect again.
[21:24] <shinobi> sarnold: Is there any open code that I can use instead?
[21:24] <sarnold> maaaaybe they only publish things here when there's *new* firmware to fix bugs
[21:24] <sarnold> shinobi: not that I know of; basically everything requires firmware
[21:34]  * phillipsjk still can't find the source-code for the "ambeince" theme, specifically the palatte. The CSS files for theme in the terminator data director just deal with geometry, not color. 
[21:34] <phillipsjk> Might be faster to take a screenshot, the use the sampling tool in GIMP.
[21:56] <jeremy31> sarnold: That is normal to see errors like that from Intel wifi, sometimes the newest firmware that the kernel can use doesn't exist yet
[21:59] <shinobi_> dmesg shows: deauthenticated from 1c:49:7b:74:fb:3d (Reason: 4=DISASSOC_DUE_TO_INACTIVITY)  This is my router correct?
[22:00] <sarnold> jeremy31: cool, thanks :)
[22:00] <jeremy31> I wonder if power management is causing the issue
[22:01] <sarnold> shinobi_: probably; check ip n output
[22:03] <jeremy31> shinobi_: Is power management on in results for>  iwconfig
[22:04] <shinobi_> jeremy31: no it's off. You helped me with that a few days ago. Thanks again!
[22:05] <shinobi_> Looks like the 802.11 protocol provides deauthentication reason codes. 4 is inactivity, but I cannot find where to change this.
[22:06] <sarnold> I wonder if your router *also* has powersave settings that should be disabled?
[22:07] <shinobi_> sarnold: Yes, it does. It is not enabled though
[22:08] <shinobi_> how do I know if I am using n or g or ac?
[22:13] <shinobi_> this just showed up in dmesg
[22:13] <shinobi_> 1c:49:7b:74:fb:3d denied authentication (status 1)
[22:26] <justdoglet> Trying to install Ubuntu Server 20.04.1. Can't get a graphical installer no matter what I try. Safe graphics mode and regular mode both lead to a text-mode installer. Text-mode installer DOES NOT show all text necessary to install; for example, can't see VG members, etc.
[22:26] <justdoglet> System is Dell PE R6525.
[22:26] <sarnold> justdoglet: the server installer doesn't have graphics
[22:27] <justdoglet> sarnold: Awesome. How do I get it to show me the text it isn't showing me?
[22:27] <sarnold> justdoglet: it's been a year or so since I've gone through the installer, but the storage section was a bit confusing -- iirc you've got to expand storage sections
[22:27] <justdoglet> For example, can't see members when I'm adding to VG.
[22:27] <justdoglet> Yeah, but I can't see anything when I expand. Even prompted to use the newest installer, updated.
[22:28] <justdoglet> Is there a way to force different text colours? Accessibility? I'm kind of desperate.
[22:29]  * justdoglet sighs and regrets.
[22:51] <lpalamede> Hello, I have downloaded a hirsute server cloudimg and I saw no user/password to connect to this ova on my virtualbox. Please let me know where to get these
[22:57] <jerry> i upgraded to xubuntu-20.04.1-desktop-amd64 a few weeks ago and suddenly i have no ethernet interfaces
[22:57] <jerry> any ideas?
[22:58] <jeremy31> jerry: any result from terminal for> dpkg -l | grep linux-modules-extra-$(uname -r)
[22:58] <jerry> i'll have to check, i shut it down and it's not accessable atm
[23:00] <jerry> bbiab
[23:21] <shinobi_> I can't move files to the trash on zfs filesystems (non-system partition). Is there a way tell if it's mounted with my uid?
[23:21] <lpalamede> seems like no one is using the daily builds
[23:25] <bippt> I have an update in Ubuntu Software but when I click <install> it looks like it downloads the updates and then they reappear as an update to be installed. One is a bios update (thinkpad x1) and the other looks like it is closely related. Is there something I need to do to get them to install?
[23:30] <sarnold> bippt: maybe try running sudo apt update && sudo apt upgrade  from the command line, maybe you'll get some messages back that explain what's going on
[23:31] <bippt> sarnold, ok, i'll give it a shot
[23:36] <pcfreak30> Hello, I am having an issue suddenly where the network service hangs on 18.04 server.  When i go to recovery, i see the recovery-menu try to run networking.service but its not there, and I can see systemd-networkd + netplan seem to be used. I can use the network on a live cd. What should I be looking at?
[23:40] <sarnold> pcfreak30: dmesg, journalctl, ip route, ip addr, ip link, networkctl status
[23:42] <pcfreak30> how do i enable networking on a root shell?
[23:42] <derpadmin> whut?
[23:42] <pcfreak30> b/c if i choose any ncurcuses option it will hang
[23:42] <derpadmin> you mean single user mode?
[23:42] <pcfreak30> yes recovery mode
[23:43] <pcfreak30> as I assume the service isnt started
[23:43] <derpadmin> hmm, I think there is no network, used to be loaded after (back in the days in sysmtemV)
[23:43] <derpadmin> run level3 it was
[23:43] <derpadmin> now with systemd, unsure
[23:43] <derpadmin> perhaps ask systemd?
[23:43] <Bashing-om> pcfreak30: ^^ Too: at boot-time netplan 'renders' a systemd-networkd config in /run/systemd/network/ - check there are files in there. If not, then there is no active network config. -> anything : journalctl -u systemd-networkd.service ??
[23:44] <pcfreak30> So how do I get the network prepared if it hasnt booted up fully as by that time it just hangs and i cant use any tty
[23:44] <pcfreak30> ok, thanks will try
[23:47] <bippt> sarnold, got the updates to work. ran apt and then restarted. thanks!
[23:47] <ruedii> You might want to set your wifi to reinitialize on wake instead of trying to resume on wake.  Your router might not keep persistent authentication long enough.
[23:48] <ruedii> pcfreak30, ^^^
[23:48] <pcfreak30> Bashing-om: could you please resend your last message. had to switch to laptop.
[23:49] <ruedii> You could also try to simply run an ethernet cable if that's an option.  It's much more reliable if that's a choice.
[23:49] <sarnold> < Bashing-om> pcfreak30: ^^ Too: at boot-time netplan 'renders' a systemd-networkd config in /run/systemd/network/ - check there are files in there. If not, then there is no active network config. -> anything : journalctl -u systemd-networkd.service ??
[23:49] <pcfreak30> ruedii: it is ethernet, no wifi.
[23:49] <shinobi_> how are zfs filesystems mounted? I don't see an entry in fstab....
[23:49] <pcfreak30> sarnold: thanks. wish irc could sync history like discord :/
[23:51] <sarnold> shinobi_: it's part of the zpool import process at boot
[23:51] <sarnold> pcfreak30: yeah, I think such a feature would have meant most of those services wouldn't have even started
[23:52] <shinobi_> sarnold: should I be able to move files to the trash can?
[23:52] <shinobi_> meaning on a zfs filesystem
[23:52] <sarnold> shinobi_: I don't know
[23:52] <sarnold> shinobi_: does your 'transh can' implementation want to mv files or does it copy them to the trash and then delete the source?
[23:53] <sarnold> shinobi_: does your 'trash can' implementation have the 'destination' storage on a different filesystem?
[23:53] <pcfreak30> ok figured it out
[23:53] <shinobi_> sarnold: idk it's the recycle bin on 20.04
[23:53] <pcfreak30> cloud-init is generating a file but the config seems to be a wrong nic name?
[23:54] <pcfreak30> in netplan
[23:54] <shinobi_> I can't drag/drop or cut/paste files from my zfs filesystem to the recycle bin
[23:54] <sarnold> pcfreak30: oh that would do it
[23:55] <pcfreak30> cloud.cfg.d. i didnt realize cloud-init was doing shit. its bare metal..
[23:55] <sarnold> shinobi_: do you have an ~/.xsessions-error file? maybe the errors get printed there?
[23:56] <shinobi_> sarnold: I have no file by that name
[23:57] <sarnold> dang
[23:57] <sarnold> shinobi_: hmm, sorry, I made a mistake: ~/.xsession-errors
[23:57] <pcfreak30> what would cause a nic name to change?
[23:58] <pcfreak30> enp1s0 > enp2s0
[23:58] <pcfreak30> no hardware change
[23:58] <sarnold> that feels like the second complain in two weeks about names changing
[23:58] <shinobi_> sarnold: I have no file by that name either, or nothing similar
[23:59] <sarnold> the previous person thought perhaps they'd plugged/unplugged some devices of some sort that might plausibly cause new names
[23:59] <pcfreak30> doesnt help in runing a bridge
[23:59] <sarnold> :(
[23:59] <pcfreak30> but still. im power cycling a lot. thought i currpted the fs when network manager was gone :P
