Comment 4 for bug 1829481

I do not own an AMD GPU
i have an Nvidia GPU but it happened the same thing.

The resolution is stuck at 1024*768 too BUT I suppose its NOT X-Org related

I found out that GCC got updated but the Kernel was Compiled using the old version of GCC - which breaks CC checks which leads to DKMS not working

Check if it is the same to you too - i've seen in your logs that you Kernel GCC version is 8.3 - but your system Version is 7.4

try installing gcc-8-base (or check if it is installed) - if it fixes yours i'll probably open an own bug report
