I noticed that the ISO I used was a bit old. So I upgraded the system
from source. I now run v5.8.3.33. But that doesn't solve the problem.
But I noticed the problem only occurs since I start Xorg. And I could
notice the following message:
error: [drm:pid-1:csr_load_work_fn] *ERROR* Failed to load DMC firmware
[https://01.org/linuxgraphics/intel-linux-graphics-firmwares], disabling
runtime power management.
I've search for solutions but couldn't find any. I have the following
modules loaded:
$ kldstat

Any idea how to solve that drm error?
Thanks,
