Failed to use GPU render after upgrade from 6.5 to 6.6

Help
, ,
1

I am using Arch Linux, I try to upgrade 50 6.6, but once I did it, the GPU render failed. I rollback one day before Arch package 6.6, everything work smoothly. i.e. other firmware, gpu driver, library remain the same. I try to fix this issue but still no progress after two night. I just roll back everything. I will be very appreciated if anyone could show me some clue on it.

In 6.6 output of LIBGL_DEBUG=verbose glxinfo -B

I believes these should be the root cause? Some other failure seems not relate to the graphics stack.

It looks like your mesa version is changing between your tests. It seems more likely that something in the mesa stack or another library is the cause of the issue since you can’t successfully run vkcube

When I set the snapshot day back and forth, I explicitly set two day doesn’t involve change in mesa, (16/2 and 18/2)

These are the difference package between working and failing environment:

Is your mirror up-to-date? Those new versions are pretty old.

Plasma is already at 6.6.2 in the Arch repos.

It also seems strange that your mesa output has two different versions in glxinfo

6

The mirror is not up to date, I set them to 16-Feb and 18-Feb so I could fixed the mesa version to 25.3.5 . In fact I did perform a full system upgrade at 14-Mar and then my system break on 3D graphics things. I decided to rollback at certain point to see which package causing the issue. And finally find 16-Feb and 18-Feb as working and failing day.

The package change above is output of pacman -Syyuu from 16-Feb to 18-Feb

7

I have already rule out some problem. The eglinfo with/without sudo seems is intended ( There is post in Arch Linux Forums showing this behavior: [Solved] Error 13 by amdgpu on fresh installation). And I try to eglinfo without sudo in tty session, the GPU show up properly instead of llvmpipeline in GBM platform.

Also I should confidently rule out the cause from display manager, I disable sddm and login to tty directly. Then dbus-run-session /usr/bin/startplasma-wayland but the problem persist.

When I using the kde 6.5 the journal look like

I believe other than discord, libnbd, and zxing-cpp. The remaining are all KDE related package. It seems that these three package unrelated to any graphics stuff so I guess the upgrade from 6.5 to 6.6 should be the root cause my problem.

I upgrade all these package, and downgrade only kwin to 6.5.5-3. Everything works, so I suspect the change in kwin is the root cause of my problem.
