Hi Maxim
Thank you for taking the time to answer! I am not sure how to debug
further? As it seems the black screen issue is not diagnosable from
/var/log/messages. Where else could I look for clues? In
/var/log/Xorg.0.log I see suspicious messages:

Not sure what to make of them, why is there no mention of these problems
in /var/log/messages?
Thanks again for your help!
