1. Does the problem only happen in Wayland, or only happen in Xorg
sessions?

2. Next time blinking occurs please immediately open a Terminal window
and run:

   journalctl -b0 > journal.txt

   and attach the resulting text file here.

Title:
  Display blinks black from time to time

Status in Ubuntu:
  Incomplete

Bug description:
  I have an issue since about a week or so, the display blinks black,
  like it's turning off and on again. The black blink lasts for not more
  than a second. I haven't managed to reproduce it in UEFI yet, so i
  believe it might not be a hardware issue.
