Now this is where it gets weird. Since I have Ubuntu MATE, I installed the ubuntu-desktop package to get the default GNOME environment. I kept my display manager as LightDM in case that's relevant.
Then I rebooted and tested all 3 desktop modes with default kernel options. As expected, MATE is still broken. I rebooted and tried "Ubuntu (Default)" and there were no issues whatsoever. I opened a few apps and all of them displayed OK, and used inxi -G to verify that the display server was indeed X. I rebooted again to test "Ubuntu on Wayland" and it behaved as expected too. Whatever's going wrong, it's limited to MATE, as even GNOME on X is fine. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/1882525 Title: [amdgpu] Display is corrupted upon login on Ryzen APU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1882525/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
