Cc´d Intel Gfx mailing list, in case somebody there knows something:

Cc´d Thorsten for regression tracking… forgot initially. Can also open 
bug report at a later time but so far I cannot provide many details 
about the issue.

I see. I wondered about intel-gfx driver already. Of course it could 
also be something else.

I forgot to mention: The mouse pointer was visible, but the screen 
remained black. That may again point away from Intel gfx driver. There 
has been a MESA update in between in userspace.

Currently running 4.18.7 to make sure it is no userspace issue.
