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.
