[Bug 1886129] Re: xubuntu : displays have become blank & unusable
I agree it sounds like nouveau. That box has issues with the 5.13/5.15 kernel with GNOME, KDE with nouveau on occasion, and has for a few releases now (22.04, 21.10 & possible earlier).. but was always good with Lubuntu/Xubuntu (I really use it now only for install tests & have been thinking of switching out video card) I booted Xubuntu 22.04 LTS on the box the bug report was made on - hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290) the external drive is no longer present, so I instead `apt install nfs- common` & mounted a NFS share for the random video files. Display setup was adjusted to match my setup (one screen above the other), then thunar navigated to various directories containing video files, and them dragged to an open parole player. The parole player was adjusted (window size), dragged around, maximized, un-maximized, full-screen, normal, then another video file dragged to it. This was repeated many times with many different files (may not have been the same file type). I did NOT re-create that issue. ALTERNATE/DIFFERENT ISSUE: I did have a case where a new video was started (mp4) in the existing player, the player was dragged to the other screen, then made to be full-screen; the controls went to the bottom of the screen, but the movie-picture did not increase in size; remaining the same identical size/shape as before the 'f' for full-screen was commanded (ie. picture remained small window size). If I hit 'f' again to return it to normal size; it would return to normal, hit 'f' again and it properly went to full size (controls at bottom of screen and video-picture using all of screen size)... hitting 'f' repeatedly to return to window, then back to full-screen (not pressing 'f' quickly; giving it time to cope given this box is old/slow) & the issue of black-background, controls at the bottom but video-picture remaining window-size would re-occur every so often (3rd time, 5th time, 11th time, 12th time, .. On some occasions the small video-picture had the rest of the display black, other times the wallpaper & thunar window was still evident. That however is a different issue.. and again maybe nouveau related so I'm going to ignore unless requested to file a new bug against it (where I'll try & re-create it & explore further, inc. on another box [hp 8200]) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886129 Title: xubuntu : displays have become blank & unusable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xubuntu-meta/+bug/1886129/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This certainly sounds like it's related to the nouveau driver.

[Bug 1886129] Re: xubuntu : displays have become blank & unusable
If I move the cursor to where I believe I placed the panel (in my QA- tests I move things around in what I consider is normal user play/configs), i do get different reaction to left-mouse clicks. I believe the session is operating normally, with just display mucked up. I suspect the left-click causes the menu to appear, which is just shown as different hyro-glyphics to when I left-click on other areas of the screen. I can't get sound from parole, but it's been closed (I would have pressed ALT+F4 etc to attempt to re-gain control over session) so I can't even use sound to confirm session is running correctly (just display isn't). Not all behavior is predictable, but I had multiple windows open & given I cannot see the actual display, it's very likely this is the reason (on occasions the background for both displays becomes white instead of black, but that could be I've just highlighted a unseen window for example). All this is guess as the displays are unusable. /var/crash is empty ! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886129 Title: xubuntu : displays have become blank & unusable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xubuntu-meta/+bug/1886129/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

** Description changed: - Xubuntu groovy QA-test (live) on + Xubuntu groovy QA-test (live) on hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290) No issues during test before this issue, I'd mounted an external drive and was using random found files to open & view files using installed apps. On opening a movie type of file, it started playing in parole on one display, I was jumping forward to different parts of the video file expecting to soon close & it and move to next file, alas both displays became unusuble ** problem at first no issues moving the 'video' forward, then both screens suddenly showed blocky-graphics (pre-digital era untuned-tv) which seemed to change on mouse clicks. At first I found pattern hard to detect, as it switched black&white, colored-blocks, then black-screen with cursor. It settled down to black-screen with cursor (correct except black screen), right-click would make it black-white-blocky (like untuned analogue tv), right click again and it would return to black background with normal cursor. On occasion both displays flicker white though (the image on right click seems to vary on where the mouse-pointer is) My Xubuntu/XFCE gui session is gone & unusuable. ** expected result I expected `parole` to cope with my various jumps in the video file, until I closed it. I see no squashfs errs in dmesg/journalctl, both show issues with `nouveau` [440.365961] + Possibly I should have filed against `xserver-xorg-video-nouveau` or + even `libdrm-nouveau2` (it was a video playing) + + I won't take a photo, it'd require video as screen isn't always static + though it is most of the time (depends where pointer is on screen) + ProblemType: Bug DistroRelease: Ubuntu 20.10 Package: xubuntu-desktop 2.233 ProcVersionSignature: Ubuntu 5.4.0-26.30-generic 5.4.30 Uname: Linux 5.4.0-26-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.11-0ubuntu42 Architecture: amd64 CasperMD5CheckResult: pass CasperVersion: 1.452 Date: Fri Jul 3 02:08:27 2020 LiveMediaBuild: Xubuntu 20.10 "Groovy Gorilla" - Alpha amd64 (20200701) ProcEnviron: - TERM=linux - PATH=(custom, no user) - XDG_RUNTIME_DIR= - LANG=C.UTF-8 - SHELL=/bin/bash + TERM=linux + PATH=(custom, no user) + XDG_RUNTIME_DIR= + LANG=C.UTF-8 + SHELL=/bin/bash SourcePackage: xubuntu-meta UpgradeStatus: No upgrade log present (probably fresh install) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886129 Title: xubuntu : displays have become blank & unusable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xubuntu-meta/+bug/1886129/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
