Thanks. Not all logs will show the problem since a full lockup might prevent pending log messages from reaching the disk. The log in comment #10 however looks related and ends with some problems in the 'amdgpu' kernel driver, which is what I expected.
So this bug is now assigned to the correct component. You should try a newer kernel like https://kernel.ubuntu.com/~kernel- ppa/mainline/v5.13-rc2/amd64/ to see if the problem has already been fixed. ** Changed in: linux (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1928600 Title: [amdgpu] Gnome locks up with artifacts on screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1928600/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
