basic configuration details
When I try to boot SteamOS I end up with just a black screen.
Xorg.0.log contains this error but I'm not completely sure if it is the cause:
(EE) AMDGPU(0): drmmode_do_crtc_dpms cannot get last vblank counter
I also tried installing debian kernel 5.0.2-1~exp1, mesa 19.1.1 and all the
relevant xserver-xorg-video-* 19.0.1 but the problem persisted.</pre>
