Thanks for the bug report. This looks like a bug in the kernel graphics driver. Please:
1. Run this command: lspci -kv > lspci.txt and attach the resulting text file here. 2. Try some other kernel versions from https://kernel.ubuntu.com /~kernel-ppa/mainline/?C=M;O=D ** Tags added: amdgpu ** Summary changed: - Gnome locks up with artifacts on screen + [amdgpu] Gnome locks up with artifacts on screen ** Package changed: gnome-shell (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1928600 Title: [amdgpu] Gnome locks up with artifacts on screen Status in linux package in Ubuntu: Incomplete Bug description: With this hardware configuration this issue has been a problem only when suspending or resuming from suspend under 20.04. Having decided to upgrade through 20.10 to 21.04 to see if things improve enough to help me identify which package to report a bug against things have become significantly worse. With 20.04 it was an occasional occurrence found when returning to the computer. Either it was stuck in the suspend process with a blank screen or one with artefacts on, or it would start the resume and then lock. On the upgrade to 21.04 (I didn't stop on 20.10 for more than enough time to tidy up and upgrade again), the system seemed improved initially - including notably improved boot times (no idea if that is related). After a bit of checking things out I went to enable the PPAs that had been disabled (Teamviewer, Nextcloud, Anydesk and Chrome - all of which have been installed after the problems were initially noted). When the window to authenticate popped up the screen filled with artefacts and I had to reset. After several attempts to reboot into a working desktop variously booting to artefacts, or getting artefacts immediately after logging in (usually when opening and maximising a terminal to capture the logs for later) I managed to change from Wayland to X.Org and logged in successfully with no problems for the rest of the day (including a Jitsi meeting lasting about 4 hours or more). The next day (today) suspend and resume is causing problems as before, boot has slowed down again (again, no idea if this is related). Compared to 20.04 there are more frequent locks (it had reached one every other day, but now it is more frequent - 4 today so far). Key things I have noted: - it is significantly worse under Wayland (to the point of being unusable) - it usually happens during the suspend / resume, but not always - when using the desktop it will always related to moving or resizing a window - leaving the PC powered off for a few minutes helps to get a reliable reboot (as in, if you reboot too quickly you get artefacts immediately after logging in) ProblemType: Bug DistroRelease: Ubuntu 21.04 Package: gnome-shell 3.38.4-1ubuntu2 ProcVersionSignature: Ubuntu 5.11.0-17.18-generic 5.11.12 Uname: Linux 5.11.0-17-generic x86_64 ApportVersion: 2.20.11-0ubuntu65 Architecture: amd64 CasperMD5CheckResult: unknown CurrentDesktop: ubuntu:GNOME Date: Sun May 16 19:23:00 2021 DisplayManager: gdm3 InstallationDate: Installed on 2020-10-16 (212 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Release amd64 (20200423) RelatedPackageVersions: mutter-common 3.38.4-1ubuntu2 SourcePackage: gnome-shell UpgradeStatus: Upgraded to hirsute on 2021-05-15 (1 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1928600/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
