[Desktop-packages] [Bug 1882525] Re: [amdgpu] MATE desktop is corrupted upon login on Ryzen APU
I've discovered some useful info about this bug. First, there's a forum thread about it with lots of good info: https://ubuntu- mate.community/t/20-04-display-issues-with-amd-gpu/21648/37 Second, a new workaround. To recap, the first workaround I found was booting with nomodeset, but that disables all hardware acceleration. The new workaround, as detailed in the forum thread, is to open MATE Tweak, and in the Windows tab, change the window manager to Marco (no compositor). Third, we found the upstream bug in xf86-video-amdgpu: https://gitlab.freedesktop.org/xorg/driver/xf86-video-amdgpu/-/issues/10 . I believe this is packaged as xserver-xorg-video-amdgpu in Ubuntu. It's been fixed upstream and the Ubuntu Mate devs will include it in 20.04.1 is possible. Fourth, bug #1873895 appears to be the same bug, but originally reported as manifesting in Xubuntu. Maybe this is a duplicate. ** Bug watch added: gitlab.freedesktop.org/xorg/driver/xf86-video-amdgpu/-/issues #10 https://gitlab.freedesktop.org/xorg/driver/xf86-video-amdgpu/-/issues/10 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1882525 Title: [amdgpu] MATE desktop is corrupted upon login on Ryzen APU Status in marco package in Ubuntu: New Status in mesa package in Ubuntu: New Status in xorg-server package in Ubuntu: New Status in xserver-xorg-video-amdgpu package in Ubuntu: New Bug description: Today I upgraded from Ubuntu MATE 19.10 to 20.04.

[Desktop-packages] [Bug 1882525] Re: [amdgpu] MATE desktop is corrupted upon login on Ryzen APU
Today I had some more time to play around with my computer so I tried testing your hypothesis. I rebooted into my current software configuration with no workarounds as a control, and reproduced the bug as expected. Then I downgraded my system to the Marco version from 19.10 (1.22.3) by downloading it from the Ubuntu packages site, along with the necessary versions of libmarco-private2 and marco-common. Then I installed the .deb's with dpkg, and rebooted. The bug was still triggered so perhaps that suggests it's not a bug in Marco? Anything else I could try testing to narrow it down? Obviously it's confusing because GNOME doesn't trigger it, but Marco seems to regardless of version. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1882525 Title: [amdgpu] MATE desktop is corrupted upon login on Ryzen APU Status in marco package in Ubuntu: New Status in xorg-server package in Ubuntu: New Status in xserver-xorg-video-amdgpu package in Ubuntu: New Bug description: Today I upgraded from Ubuntu MATE 19.10 to 20.04.

[Desktop-packages] [Bug 1882525] Re: [amdgpu] Display is corrupted upon login on Ryzen APU
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 Desktop Packages, 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 Status in linux package in Ubuntu: Incomplete Status in xserver-xorg-video-amdgpu package in Ubuntu: Incomplete Bug description: Today I upgraded from Ubuntu MATE 19.10 to 20.04.

[Desktop-packages] [Bug 1882525] Re: Display is corrupted upon login on Ryzen APU
A quick update. I tested to see if kernel version affects this bug, and it appears not to. I booted up the previous installed kernel on my system (5.3.0-55) without the default options and got the exact same issue. Likewise, using the old kernel with nomodeset eliminates the corruption at the expense of hardware acceleration (inxi -G says my renderer is llvmpipe). As I didn't have this issue using that kernel on 19.10, I believe this points to something in the userspace that was updated when I went to 20.04. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1882525 Title: Display is corrupted upon login on Ryzen APU Status in xorg-server package in Ubuntu: New Bug description: Today I upgraded from Ubuntu MATE 19.10 to 20.04.

I've attached a picture of my monitor showing the issue for reference. My hardware is a home-built PC with an ASUS Prime B450M motherboard, a Ryzen 3 2200G APU, and using that APU's integrated graphics. In terms of software I'm running Ubuntu 20.04, which I just upgraded to and did a software update on. I have Linux 5.4.0-33-gene
