> The screenshot in comment #1 looks like a kernel/driver bug. Do you always see that corruption when the bug happens?
No. Sometimes it just freezes for around 30 seconds and everything gets back to normal. Sometimes the behaviour on the screenshot happens and it won't ever get back to normal (I sat there for 5 minutes before giving up, had a bit of ghosting on the display afterwards because of the glitch keep turning the pixels on and off randomly.) Here's the journal log for the ~30 seconds freeze. I disabled the second display at 07:58:33 and the main display started to be responsive at 07:59:19. Thanks for looking over this! ** Attachment added: "journal.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1981559/+attachment/5603053/+files/journal.txt -- 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/1981559 Title: [amdgpu] Gnome Freezes When Second Display is Turned Off Status in gnome-shell package in Ubuntu: Incomplete Bug description: When second display is turned off, gnome will freeze for about 30 seconds before it starts working again. Sometimes, it freezes indefinitely with the screen glitching, forcing me to reboot. The indefinite freezing happens when I have a lot of windows open on both displays. Wake up from suspend takes too long - about 30 seconds - and the “Join Displays” option changes to “Single Display” and the primary display option changes to the second display. My graphics card is AMD Radeon VII. I run into this issue on a fresh Ubuntu 22.04 installation. Displays are 1440p and 1080p @ 144Hz. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu82.1 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME DisplayManager: gdm3 DistroRelease: Ubuntu 22.04 InstallationDate: Installed on 2022-06-25 (18 days ago) InstallationMedia: Ubuntu 22.04 LTS "Jammy Jellyfish" - Release amd64 (20220419) Package: gnome-shell 42.2-0ubuntu0.2 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 5.15.0-41.44-generic 5.15.39 RelatedPackageVersions: mutter-common 42.2-0ubuntu1 Tags: jammy third-party-packages Uname: Linux 5.15.0-41-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin lxd plugdev sambashare sudo _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1981559/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
