[00:57] = rescan? [01:23] i have a gpdwin 3 and i installed ubuntu on it.

"Terminal", "Command line interface", [04:31] Samian: to refer to what [04:32] to who? [04:32] I think 'terminal' and 'command prompt' are more general and useful to most people [05:35] I want to disable copy past shortcut (using command) ? without installing any additional application. === rifl` is now known as rifl === Guest59 is now known as atal181 === mijora1 is now known as mijora === rifl is now known as Guest1228 === rifl` is now known as rifl === rifl is now known as rifl` [07:44] Hi! Has anyone encountered this libpython error when upgrading an ubuntu 20.04.2 LTS? https://imgur.com/a/MyHEsIc [07:48] nvm, fixed it with `apt install -f` === Guest80 is now known as branant === prxq_ is now known as prxq [09:00] I've lost the handle of the people who helped fix my DNS problems yesterday, but thought you might like to know that I reported this to Proton, who have acknowledged a bug in their client and are working on a fix. [09:05] hellp [09:05] when i connect ethernet wifi will disconnect [09:05] any idea ? [09:19] My wifi gets disabled randomly in Ubuntu 20.04. I have tried all manner of power management settings configuration and nothing seems to work. [09:20] What can I do to monitor for events that are causing wifi disabling? [09:25] frib: I had a similar problem recently with a Dell XPS with Killer wifi, which is notoriously unreliable. In the end it turned out an unfixable hardware problem and I had to get a new machine on warranty. [09:25] In my case the problem was that the wifi card would just entirely vanish from the system for a while, even after reboots, then just as mysteriously it would return again. [09:32] rob, mine doesn't appear to be a hardware problem as it visibly gets disabled in Network Manager and I can simply manually turn it back on again [10:27] goodafternoon [10:28] welcome theMajor [10:30] Hi [10:31] i want to config gui and vnc on ubuntu server [10:31] server is Oracle cloud instance [10:33] hello [10:34] welcome p3rL [10:34] how do i fix or avoid this error [10:34] -bash: warning: setlocale: LC_ALL: cannot change locale (cs_CZ.UTF-8) [10:34] madhan: please no crosspost on several ubuntu channels [10:34] when ever i login my server it get this error [10:34] i am getting this on my ubuntu server [10:36] lotuspsychje yes i tried [10:36] p3rL: https://askubuntu.com/questions/89976/how-do-i-change-the-default-locale-in-ubuntu-server [10:38] ok the big question and don't get angry for asking but ubuntu vs popos, why should one choose ubuntu over popos [10:38] toddc thanks [10:38] letme read this [10:39] theMajor: support by third parties for example [10:40] native zfs for example [10:40] start the topic in #ubuntu-discuss if you like theMajor [10:41] various client / server variants, and so on. [10:42] is there a sleep alternative that will break with any key stroke and not just ctrl-c? === Guest96 is now known as Ritnara === Ritnara is now known as Maxii [11:02] I assume you mean in bash? a loop looking for a keystroke would be an alternative. [11:05] you can use $SECONDS in the loop for the sleep time element. [11:07] you could also use `date` if a specific time is important not elapsed time. [12:25] i got an nvme drive that is dying [12:26] what is the safest way to try and copy the disk to a file? [12:26] i drive gnome disks but it just craps out on me [12:27] goddard: try a photorec recover on it [12:28] save as much data as you can [12:36] ill give it a shot [12:36] not super critical as its just a game save i want off it [12:36] but it would be nice to not have to play that far [12:39] hey at some point I told a ubuntu 18.04 box to stop loading the graphical UI on startup ... and now I can't figure out which service needs re-enabling and starting [12:39] I'd have thought lightdm - but it doesn't seem to be there [12:39] gdm ? [12:39] something with graphical target ... [12:40] root@prometheus:/lib/systemd/system# grep -RIi graphical . [12:40] sudo systemctl set-default graphical.target [12:40] yeah I looked at that :P [12:40] aha! [12:40] ioria, +1 [12:40] * stevenm__ tries rebooting === llorllale1 is now known as llorllale [12:42] nah that doesn't seem to have done it [12:42] graphical.target loaded active active Graphical Interface [12:42] active - but not running [12:43] stevenm__, so you did something else; can you restart gdm with sudo systemctl restart gdm ? [12:43] ioria, according to 'dpkg -l' this system is lightdm, not gdm [12:43] ubuntu 18.04 has gdm [12:44] and 'systemctl enable lightdm' just gives me a warning [12:44] systemctl enable gdm [12:44] ah sorry - good point, this is actually ubuntu mate 18.04 [12:44] oh [12:44] stevenm__, sudo dpkg-reconfigure lightdm [12:44] k - it did... something? returned me to the prompt anyway [12:45] no message = ok [12:45] I know :) [12:45] doesn't mean ok means it did anything useful :P [12:46] stevenm__, how did you 'tell' ubuntu to not load the graphical UI ? [12:46] no idea - was probably over a year ago - or more [12:46] aha! graphics on boot! [12:46] stevenm__, cat /proc/cmdline [12:46] stevenm__: did you manually adjusted the runlevel of the system [12:46] that did it :) [12:47] stevenm__: what was the solution? [12:47] possibly that dpkg-reconfigure of ioria's ? [12:47] it's booted straight into the desktop though - no login screen [12:47] which is ... odd [12:48] oh, auto,ogin [12:48] stevenm__: that makes total sense. Hmm maybe check if autologin is enabled [12:48] not if you use autologin [12:48] yup it's on in /etc/lightdm/lightdm.conf [12:48] or edited /etc/lightdm/lightdm.conf [12:49] :) [12:49] well, iirc, that file is not default (in that location) you need to create it [12:49] stevenm__: glad it is solved for you [12:50] this "desktop" is actually just a shallow-depth 1U rackmount in a datacentre [12:50] i see [12:50] originally I wanted to remote into it using NoMachine... but then found it wasn't very quick [12:50] so then disabled the graphics.. swapped to X2Go [12:50] but now I'm sick of X2Go and I'm swapping back :) [12:52] stevenm__: my experience with nomachine was actually pretty good never used X2GO so can't compare [12:53] theMajor, I think since NoMachine 4 it very much depends on how good the GPU is at helping with the encoding [12:53] which this machine isn't great at [12:53] stevenm__: the only thing with nomachine is that it doesn't like wayland [12:53] but there are so many quirks and issues with X2Go (even the latest firefox has issues) and I've found with one false move it'll kill your sessions :( [12:54] theMajor, actually I've got a Fedora 34 box running gnome 40 & wayland... and I can NoMachine into it just great [12:54] and it works far better than the built in VNC & RDP of gnome-remote-desktop which is now in gnome 40 [12:56] gnome40 should be a lot better with remote access, but ubuntu is not that far yet. [12:56] yeah I'm hoping to use Ubuntu (rather than Ubuntu MATE) on my work lappy when it hits 22.04 - with hopefully both RDP and AD out of the box [12:57] stevenm__: have to be honest that i have not tried it in gnome40 yet. i was running on xorg than for the time being. but hey maybe i switch and give it a try again as i have noticed that wayland performs better than xorg. I don't know if it is much better but they developed it for a reason [12:57] Nope, it will not be introduced with an LTS. [12:57] 40 won't be? [12:57] any way i can rotate my screen from an ssh session? [12:57] i wanna see what is going wrong and why the screen just goes black [12:58] goddard, maybe an xrandr command? [12:58] with DISPLAY=:0.0 at the start [12:58] rotating screen, does that help? [12:59] i tried xorg and wayland [12:59] its the gpd win3 [12:59] oh wait, impish 21.10 will have gnome41 https://discourse.ubuntu.com/t/impish-indri-release-schedule/18540 [12:59] its screen is a sideways screen [12:59] makes no sense whatsoever but that is just the way it is [12:59] goddard, maybe? DISPLAY=:0.0 xrandr -o right [12:59] thanks ill try [13:00] (or 'left', or 'normal' or 'inverted') [13:00] plasma was able to rotate no problem [13:00] only gnome has some kind of issue [13:00] oerheks, are you trying to say there will definitely be no GNOME 40 in 22.04? and if you are, how can you know for sure? [13:01] i mean in 9 months GNOME 40 might be considered stable enough to support for 5 years [13:01] i found 21.10 will have 41, see last post [13:01] yeah I saw that too [13:01] which is why it made no sense you saying 22.04 wouldn't have 40 :P [13:02] oh yeah - i missed your link [13:02] stevenm__, if it was introduced, not with an LTS [13:03] yeah the command works [13:03] but still black screen [13:03] doing DISPLAY=:0.0 xrandr -o normal doesn't bring it out of the blackness of the void [13:03] hurrah - never done that before, yay for 2 seconds of googling (although it helps to know what to google :P) [13:11] i guess ill just use plasma [13:12] i never tried rdp in gnome 40 is that possible out of the box? [13:12] vnc is [13:12] Hi all. I install lsyncd and it works when I run it with options on the foreground but won't start as a service. I've tried to look at logs, but don't find any relevant errors (yet). It seems to be old-fashioned in that it start via a script in /etc/init.d/lsyncd ..anybody seen this before? [13:13] they call it screen sharing in ubuntu [13:17] <_moep_> hi there! Is it possible to restrict the rights so that a user is not allowed to install new snaps (via snapd) without sudo? [13:18] goddard: so basicly it is vnc and not actual rdp [13:18] it has a rdp client [13:18] but not rdp server [13:19] goddard: and that last one would really be helpfull [13:19] everyone has their own use case i suppose [13:19] personally never needed it [13:20] goddard: if that option was there we would not have to fiddle with things like nomachine. no i am a more terminal kind of guy so i can always ssh in and stuff but sometimes you just need your desktop for whatever reason [13:20] goddard: even now i am ssh-ed into my machine from work [13:21] goddard: meaning this is my irc from home :) [13:21] moep any new user has no sudo rights [13:21] only the 1st created during install * === cmagina_ is now known as cmagina [13:24] theMajor so why not vnc? [13:24] personally i dont want to use any microsoft technologies [13:24] no samba, rdp, edge, vscode, etc..etc.. [13:25] even if its just a translation technology created by some one else like samba [13:25] but i understand some sysadmins may need to work in an environment with other OS [13:25] i dont [13:25] usually you get a better experience doing it the purely Linux way [13:26] proton is the only thing i tolerate at the moment [13:26] _moep_: isn't that how it is already? [13:27] well i use edge all the time and vscode and samba and am primarily c# programmer honestly i dont care if microsoft created it to me at the end of the day that isnt a reason to use good piece of software [13:27] goddard: interesting idea [13:27] goddard: what's the linux equivalent of vscode? [13:27] i dont am just a hobby programmer ;) [13:27] goddard, i'm not particularly happy that the wayland-effort (in it's many many ways) doesn't collectively seem to have considered an alternative for VNC or X11 forwarding [13:28] neovim is better than vscode [13:28] instead we're seeing GNOME building in freerdp's RDP server implementation into their desktop / wayland === RedNifre_ is now known as RedNifre [13:28] and much lighter [13:28] goddard: "better" in what way? [13:28] which is - err... nicer than VNC I guess? but really? just imitating MS? [13:28] but still as a programmer myself a full IDE will always be better [13:28] and quicker to get going [13:28] if you dont need quick then learning NeoVim will be tremendously useful [13:29] gordonjcp: u havent yet found an equivalent for vscode [13:29] stevenm__its a different protocol [13:29] what is? [13:29] bigpod: not really, although I've only relatively recently started using vscode and it's quite a game-changer [13:29] vscode is a web browser that consumes massive amounts of ram to show a text file [13:29] it is pretty silly to use it [13:29] !discuss [13:29] Want to talk about Ubuntu, but don't have a support question? /join #ubuntu-discuss for non-support Ubuntu discussion, or try #ubuntu-offtopic for general chat. Thanks! [13:29] sorry [13:30] please stay ontopic guys, we got a nice #ubuntu-discuss channel [13:30] ill be in offtopic [13:30] stevenm__: honestly anything is better then VNC [13:33] <_moep_> rbasak: Im not really sure, when I install the daemon for non-root users, its possible [13:33] <_moep_> but tbo: Im new to snap [13:42] I have encrypted my total hard drive in ubuntu VM. clearly, the sysadmin can have access like physical access in the virtual environment. But there is a problem, every time my VM has been restarted, It requires entering the password to boot up. Is there any way to solve it? to boot up without entering the password? [13:42] punkgeek: yes, don't use encryption [13:44] punkgeek: how do you expect the system to get the decryption key? [13:45] There are other options. You can provide a script that obtains the key however you want. [13:45] hi, where can I find information about motherboard compatibility ? [13:45] google the motherboard model + linux gives me not much infos [13:48] dob1: ubuntu has a compatibility list, but it's mostly for assembled systems [13:49] there's no database for stuff like that i know of [13:50] most if not all montherbards should work with ubuntu [13:50] motherboard generaly doesnt have anything to do with linux compatibility [13:55] Actually, I want to protect my data in the webserver directory. But it should be mounted after boot up automatically. Do you have any suggestions? [13:55] !hardware | dob1 [13:55] dob1: For lists of supported hardware on Ubuntu see https://wiki.ubuntu.com/HardwareSupport - To help debugging and improving hardware detection, see https://wiki.ubuntu.com/DebuggingHardwareDetection [13:55] punkgeek: yes, don't use disk encryption [13:56] For example, can I use a dynamic password and receive it from an API server to mount it? [13:57] punkgeek: maybe, but why? [13:57] disk encryption doesn't actually solve anything [13:59] So how can I protect the files from physical access?without encryption [14:00] punkgeek: you can't [14:00] punkgeek: unless you enter the key yourself on boot-up === genii-core is now known as genii [14:00] if you automatically decrypt the drive, how do you stop someone else doing that? [14:00] punkgeek: think about your threat model [14:00] punkgeek: what are you actually trying to protect against? [14:02] punkgeek, you could get a USB key with physical number pad that handles the encryption on HW level internally ... [14:04] ogra`: that would still require manual intervention [14:04] yes [14:04] punkgeek: if anything automatically decrypts the drive, then there's no point in encrypting the drive [14:04] well ... [14:05] if you want to protect yourself from drive theft this is actually a proper protection ... [14:05] I've thought about USB key and it is good but I can't give it to sysadmin [14:05] but thats about the only use-case i guess [14:06] punkgeek: in your use case, there is no point in encrypting the drive if you're just going to automate decrypting it [14:06] exactly [14:06] punkgeek: where physically is the data? [14:06] punkgeek: either encrypt it and someone decrypts it at every boot or you don't encrypt it [14:06] punkgeek: how likely is it that someone will physically attempt to steal the disk that the data is on? [14:07] hey [14:07] hello [14:08] it can happen from our communist government. and I can't move the data outside the country. [14:08] punkgeek: then come up with a policy of manually decrypting the drive [14:08] yup [14:09] you will need to enter some sort of key that only you know [14:09] automatically decrypting the drive won't help you here [14:09] punkgeek: either way, this is beyond the scope of this channel. Feel free to ask for more input in #ubuntu-security [14:09] punkgeek: also, consider that this is the least likely way that anyone will exfiltrate your data [14:10] punkgeek: you basically have two distinct infosec threats [14:10] punkgeek: your two threats are Mossad, and Not-Mossad [14:11] punkgeek: if Mossad are after your data, you can't do anything about it. They'll abduct you, beat the password out of you, shoot you on national television, and then say they didn't have anything to do with your mysterious self-inflicted decapitation by rocket launcher [14:11] !ot | gordonjcp [14:11] gordonjcp: #ubuntu is the Ubuntu support channel, for all Ubuntu-related support questions. Please register with NickServ (see /msg ubottu !register) and use #ubuntu-offtopic for other topics (though our !guidelines apply there too). Thanks! [14:11] punkgeek: if Not-Mossad is after your data, then generally speaking ensuring your code has no obvious remote exploits and you don't reuse passwords on hornypornygirls.ru is going to be sufficient [14:12] gordonjcp: please stop [14:12] punkgeek: but in general, disk encryption is going to be a tiny piece of your puzzle [14:12] gordonjcp: very innapropriate [14:19] What about this theory. I can write a script to find the hard disk hash. then I send it to an API server. If the has is be correct, the API server will send the password to the VM to decrypt the partition. So in this case, If someone goes through the rescue mode, the total disk hash wouldn't be correct. [14:21] punkgeek: I don't know if that would work [14:21] Hello, Any SRU/MRU meeting today ? [14:21] punkgeek: the hash would change all the time surely? Like, as you write logs/edit pages/log in and out storing stuff in wtmp? [14:23] punkgeek: it's still automated. No point. Please bring further ideas to #ubuntu-security. [14:23] bittin: #ubuntu-devel maybe? [14:23] Okay, Thank you sir [14:23] leftyfb: #ubuntu-meeting but thx anyways [14:33] Hi all === Pony is now known as Guest7465 [14:35] Hi. Even after reading the docs https://www.freedesktop.org/software/systemd/man/systemd.mount.html#x-initrd.mount - I don't really understand what the mount option 'x-initrd.mount' in /etc/fstab does. Could someone, please, explain? [14:36] https://www.recompile.se/mandos is interesting [14:37] But separately, punkgeek could you just have a separate partition and filesystem for the one directory you want encrypted? [14:37] Then boot without that, and unlock and mount it manually afterwards [14:44] rbasak: encrypted home gives the same functionality and has already been suggested in #ubuntu-security === sharperguy_ is now known as sharperguy [15:05] Hi, I have limited space on an SSD and would like to have an encrypted boot and root partition on the ssd, and then have an encrypted /home partition on a separate hard drive. Is this possible? [15:05] I'm assuming I could just follow this https://help.ubuntu.com/community/Full_Disk_Encryption_Howto_2019 and create another luks that has /home in, just like for / and /boot ? [15:09] * cbreak has an encrypted root pool via zfs native encryption [15:10] and zfs encryption is by dataset, so my homedir could have its own key === Guest53 is now known as Guest50 === Guest50 is now known as Guest53 [15:20] hey, my j1800(asrock d1800m) can't play any media unless pulseaudio is killed in a loop; it doesn't detect the analog output from realtek sound card and the hdmi out audio is broken/no audio plays [15:20] can someone help me out; even if I don't kill pulseaudio in a loop [15:20] no audio plays [15:21] if I just reboot rn and launch it up it won't really work at all [15:21] other than letting me superficially set loudness [15:23] pulseaudio daemon doesn't write any errors to stderr [15:24] mpv/application doesn't respond with any failures [15:24] but it also doesn't play the audio it decodes [15:24] but at the same time can partially(at times with dropped frames) decode 1080p@60 vp9 video [15:57] i upgraded focal->groovy->hirsute, and now vncserver with startplasma-x11 & in ~/.vnc/xstartup doesn't work, complaining about not being able to find the DISPLAY; DISPLAY=:1 and VNCDESKTOP is also set correctly [15:58] shimbles: haven't you been through all that yesterday with the same question? [16:00] i'm not sure i understand the question; is there additional information i can provide that will help you suggest a way to figure out how to fix it? [16:01] i don't have that knowledge. Just saying that you been here yesterday too with the same issue and was helped by others? [16:01] i think you need to stop talking to me, now. [16:01] shimbles: echo $XDG_SESSION_TYPE [16:02] if nothing works either reinstall 21.04 and see if it works then if not, stick with LTS [16:02] shimbles: please be respectful to those that are offering assistance [16:02] thanks leftyfb [16:02] he's not offering assistance, he's telling me to stop talking [16:02] Howdy...I have/had a headless Ubuntu 18.04 machine where I did "apt install ubuntu-desktop" and have 2 problems... (1) is when I `systemctl start gdm` the thing that pops up has "Welcome!" instead of login, and says my user already exists so can't create one. How do I get the login? (2) `systemctl enable gdm` complains "The unit files have no installation config..." so can't enable. [16:02] i do not shimbles [16:02] if he continues to stalk me around different channels, I will file harassment charges and subpoena his identity [16:02] sigh [16:03] just do as you please, IF you actually know what harrasment is [16:03] XDG_SESSION_TYPE was set to tty [16:03] shimbles: ok, No sense in helping someone who is hostile and threatening legal proceedings. good luck. [16:04] [10:01:15 AM] i don't have that knowledge. Just saying that you been here yesterday too with the same issue and was helped by others? [16:04] [10:01:25 AM] i think you need to stop talking to me, now. [16:04] he literally showed up here and in #kde to chastise me for asking the same question yesterday, and not managing to fix it [16:04] shimbles, just ignore him. he's the "grumpy" dude of the channel. don't worry about it! :-) [16:05] troll elswhere shimbles [16:05] ignore it is [16:05] you are the one trolling. you are not providing assistance. you are pointing out to others that i asked the same question yesterday, and that they should not help me. [16:05] hello, pulseaudio is not started here after reboot [16:05] I always have to start it manually (and then it works...) [16:06] I tried: systemctl --user reenable pulseaudio [16:06] leftyfb hopped on to add to your toxicity without reading what you actually said; and what you actually said "look, he was in here yesterday!!! dont help him!!!" made no sense. [16:06] but then I get the error: Failed to connect to bus: No such file or directory [16:06] any idea what's wrong? I guess it's related to dbus [16:06] shimbles: it tried to help but if you see it that way, have a nice day [16:06] you did not try to help. where did you provide technical assistance? [16:07] sigh [16:07] Mekaneck, now stop please, thanks. [16:07] shimbles: in reading your posts from yesterday, it looks like the only purpose you have for a GUI and VNC is to access a web URL listening on localhost. You know you can still access this by way of your remote machine and ssh right? [16:07] oerheks: i'm doing nothing wrong... but ok, if you guys see it that way... [16:08] leftyfb i am specifically trying to get Apache Guacamole to continue to work on Ubuntu Hirsute. Guacamole itself is working, but something broke from groovy to hirsute such that I can't get the vnc server to serve up startplasma-x11 [16:08] shimbles, are you in Wayland or Xorg session? [16:09] wayland is standard now .. [16:09] oerheks: I asked the same, but was told "tty" which means they are running the command over ssh and not locally [16:09] oerheks I am on AWS, the instance was upgraded from focal->groovy->hirsute; i have not figured out how i might disable any wayland config changes as of yet; i read that for KDE Plasma on Hirsute, wayland is not the default yet. [16:11] I guess I solved #1 ... just let it create a useless user, then `killall -u uselessuser ; userdel -r uselessuser` [16:11] on focal and groovy, i had not yet managed to get vncserver to run at startup and was running it manually, and it was working; so my ~/.vnc/xstartup file, which contains xrdb $HOME/.Xresources; startplasma-x11 & at least used to work [16:11] shimbles, get a fresh image from aws? .. i would not do such upgrade path. [16:11] and make sure you run xorg .. [16:12] oerheks since I am going to patch QtWebEngine, i want to be fully upgraded; and i need QtWebEngine running in Guacamole to test my patch [16:13] i have focal / groovy images which work, but the software is somewhat out of date; i could compile the full stack (chromium, qt, pyside) although that's rather large; [16:13] on that topic, "make sure you run xorg" how would you recommend I do that? via startx? I was not doing that previously [16:14] furthermore, since DISPLAY and VNCDESKTOP are set correctly when ~/.vnc/xstartup runs, isn't X being started correctly? [16:16] since i can't fix it, i really have no choice but to compile everything on groovy; still, it would be sweet to get Plasma working on Guacamole on Hirsute on AWS; i feel like there must be some minor thing i can fix :/ [16:17] i wonder about disabling wayland? what do you think oerheks, perhaps something with systemd? [16:17] echo $XDG_SESSION_TYPE , then use https://ubuntu.com/tutorials/ubuntu-desktop-aws#1-overview === Droid is now known as Mekaneck === Rey is now known as rey [16:31] hello, how can i create a "dummy connection" for debugging purposes to any ip (ex 127.0.0.1) on a specific port (ex, port 4000) [16:31] tcp connection [16:33] BinarySavior: to listen, or to connect? [16:33] netcat (nc) can do both [16:33] Or you might be interested in socat [16:34] i have a python script that monitors for any connection on a specific port, i just want to create a connection to activate parts of my python app [16:35] it doesn't listen, just verifies that a connection exists [16:46] rbasak, nc worked perfectly, i just set up a listener on localhost then connected to it [16:46] ty [17:15] Before I've decrypt a directory in the ubuntu that people can have physical access, what cases should I checked before decrypting the data? because it needs to be in mounted position until restart. For example, I should check the root password not to be changed, there is not another account has been added, there is no running bad script or a script won't be run after a while to change the password. [17:17] oerheks i found switching to gnome on hirsute (which allowed me to disable wayland) didn't work either :/ [17:17] looks like i've got some make -j in my future [17:27] Let me explain in another way. I have a debian VM, I'am suspect the sysadmin to stoling my encrypted data. So when ever I login to my system and want to decryp my encrypted partition, What cases should I check before mounting? For example, the sysadmin may go to in the rescue mode and add another user with sudo access, So when I mount my encrypted partition, he can access to my data. [17:27] or ubuntu VM, doesn't matter* [17:29] punkgeek: your situation is no to be trusted, period. You have no way of knowing what is done to your VM by any means. It cannot be trusted no matter what you do. That said, your question is beyond the scope of this channel. Please stop cross-posting. Wait for an answer in #ubuntu-security or try #ubuntu-offtopic. You are going to get the same answer no matter where you ask though. === Marco_Polo is now known as Guest9457 === Guest9457 is now known as Marco_Polo [17:37] good evening. having issue, to suspend my laptop. "sudo pm-suspend" works. but it dont locks screen, after awaking. systemctl suspent dont work .. it only locks screen [17:38] https://pastebin.ubuntu.com/p/sWjwdCDgwy/ === jailbreak_ is now known as jailbreak === not_phunyguy is now known as phunyguy [18:16] is it possible to black a screen but not shut it off? [18:17] goddard: xset dpms has several different tools for that kind of thing, though what they do to your device is dependant upon your device [18:17] goddard: you can also just put up a big black window, some screen lockers do that kind of thing [18:18] yeah that is what i was thinking [18:18] I have an OLED so i want to save the screen from any chance of burn in, but then this OLED has some bug with Nvidia which prevents it from the signal going back to the screen once its shut off [18:18] really strange [18:19] if i wait long enough i can get it to come back [18:22] ewww [18:22] nvidia is such a pain sometimes [18:22] Hey everyone. If I added this Repo like -> sudo add-apt-repository ppa:beineri/opt-qt-5.12.2-bionic ...and did the update. How can I remove it just for safety [18:23] cart_man: depending upon what you want to do, you can either comment the lines out of your sources, in case you want to put it back again at some point.. or you can use ppa-purge from the ppa-purge purge package to remove the ppa and everything that was installed from it [18:24] In gnome settings "Performance" option is missing. See - for example of what it should look like https://askubuntu.com/a/1343879/37577 [18:25] What i see https://ibb.co/fn5vKj9 [18:30] nvidia wont support HDMI-CEC [18:30] https://forums.developer.nvidia.com/t/hdmi-cec-support/31445 [18:30] if they did it would probably make this bug go away [18:33] sarnold: I always get shit with adding these repos... "Held broken packages" is basically a guaranteed for me so I just want to clean them afters [18:33] afterwards [18:34] sarnold: Where is that file located that I can comment it out in?? [18:35] cart_man look at ppa purge [18:35] its a gui to manage your ppas [18:36] super simple and usually works without incident [18:36] do I install it first? [18:36] How do I run it? [18:36] ppa purge seems ...well [18:36] I can not run it like that [18:37] y-ppa-manager [18:37] if you want a gui [18:38] cart_man: it'll be in /etc/apt/sources.list or a file in /etc/apt/sources.list.d/ [18:48] Guys? I used to have 2 external monitors connected to my laptop, one displayport and one HDMI. Now I've added another displayport monitor, so I have one HDMI cable and a displayport hub connected to the laptop. It works in the dualboot Windows 10, but when I try to boot Ubuntu 20.10 it freezes during boot. If I restore the old setup with 2 monitors Ubuntu boots as well. Anyone had similar problems? [18:48] Should I file a bug report somewhere? (Where? Never had this kind of problem before..) [18:52] goddard: Thanks thats a nice too [18:52] tool [18:53] ALSO.... I am trying to build a program but my QT libs inside /usr/local/lib/ overshadow the libs that I am trying to use for the build and HENCH my build fails. How can I temporarily remove the libs from being used by my build? I still need /usr/local/lib in the path since other things need the libs in that path [18:54] runtime library [libQt5Network.so.5] in /usr/lib/x86_64-linux-gnu may be hidden by files in: /home/rt/Qt/5.12.11/gcc_64/lib [18:55] I'm going to use remote ssh for enter LUKS password. Is the interface name same as the network configuration file? I've tried this but it doesn't worked: I use this configuration but it doesn't works: GRUB_CMDLINE_LINUX="IP=51.68.177.130::51.68.177.254:255.255.255.0:linux:ens160:none" [18:55] Slartiba1t: I'd do some isolation/combination tests first. Will it work with only the displayport hub and 1 DP monitor? the hub and 2 DP monitors? the hub, 1 DP monitor, 1 HDMI? [18:56] punkgeek: no - at boot time it's the kernel name - you'd be better using the interface MAC address [18:57] TJ-: Fair enough. I'll try to cover all the cases. [18:58] TJ-: How can I find the interface name from the kernel? [18:59] punkgeek: Ethernet interfaces start at eth0 and the number increments for each discovered interface [19:01] punkgeek: I'm not sure if NFS's ip= can do MAC addresses now I'm reading up on it. I'm pretty sure I've used it that way many years ago but kernel admin guide doesn't mention it. However, the ip= command-line option is intercepted and interpreted by the initramfs-tools /init shell script and there are hooks to handle ip= in those [19:06] punkgeek: aha, yes! see "/usr/share/initramfs-tools/scripts/functions" and the function configure_networking() where it translates a BOOTIF=01-aa-bb-cc-dd-ee-ff that is set by PXE boots to a corrected MAC address e.g. aa:bb:cc:dd:ee:ff then looks up which device name has that MAC address and sets the IP= DEVICE accordingly [19:07] punkgeek: so you can 'pretend' it booted using PXE and add a BOOTIF=01-yo-ur-ma-ca-dd-re ss on the kernel comand line and moit a DEVICE from the IP= line and it should fill it correctly for you [19:07] s/moit/ommit/ === terrorjack4 is now known as terrorjack [19:13] Hi all, I was in a meet video call, when the sound started repeating and the system become unresponsive to mouse or keyboard. REISUB did not do anything. Powercycled and found nothing in logs for the moment of the crash. How to debug such problems? [19:15] diskin: maybe you could make progress using a crash kernel to collect information when it hangs, but that's not the easiest thing to set up, and then you'd have to figure out how to do the kernel debugging. it wouldn't be fun, unless that's your idea of fun.. [19:16] this 'meet'? https://meet.google.com/ [19:16] diskin: it's perhaps more approachable to remove devices from your system one at a time and try to recreate it [19:16] diskin: or perhaps if you've got 'funny' kernel modules loaded like vbox, remove those, and try to recreate it === gr33n7001 is now known as gr33n7007h [19:16] it's also not fun, but far more approachable if you're not good at debugging kernels [19:18] another possibility is that your power supply just isn't up to the task; I've seen power supplies that were pushed too far, or failing, do things like that [19:28] oerheks, yes, this meet. [19:29] sarnold, re: power supply, it's a laptop with a working battery, plugged in to AC power source, does it matter? [19:29] diskin: ah that's probably enough unless you've got crazy usb accessories attached [19:29] if that runs in your chrome browser, look there for logs? .. or wait, logs aren't generated automatically. You need to turn on logging first. https://support.google.com/chrome/a/answer/6271282?hl=en#zippy=%2Clinux [19:30] and I do have virtualbox installed, some modules loaded... but it happened 1st time in a year or so. normally the system is very stable, upwtime several weeks [19:31] oerheks, are you saying that Chrome could have logged the system crash in it's own logs? [19:31] only when enabled, yes. [19:31] when the sound card starts playing the same clip over and over again it means the kernel wasn't able to put new audio data in its buffer in time, so it's just playing what it's got.. probably the machine is hosed enough at that point that google meet logging won't be able to help [19:33] yes, the sound card was repeating some part of a word which was just said by a call participant, initially I thought it was something with his machine, but very quickly understood it was mine :) [19:35] when using meet with 5+ users, you will need 4 gb ram...
