Amdgpu Trouble

English Hardware
#1

Trouble was first noticed when a 1 minute freeze occurred: “kwin_x11[1741]: Freeze in OpenGL initialization detected”. Updating the machine resulted in the following error during boot: “kwin_x11[1431]: kwin_core: Compositing is not possible”.

Any idea?

#2

Selecting System Settings > Display and Monitor > Rendering Backend > OpenGL 3.1 seems to fix the problem.

Needed to boot into snapshot 20201007 and roll back. :frowning:

#5

Fixed failed boot by booting with ‘nomodeset’ and running the following commands:


rm -rf /lib/firmware/amdgpu
zypper dup

Suspend/resume issue still persisting.

Developers upstream suggest to track down the bug using bisection. Building a kernel from the actual version at https://github.com/openSUSE/kernel, installing and running it is straight forward. However I am lost with building older versions. Any suggestions?
