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. Rafael J.

It also may be something like CPU online/offline, however. 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.
