Public bug reported:

I have 3 screens including the laptop screen. The one connected to the
displayport is going in to power save mode and back in random
intervalls.  The other screens don't care if the displayport one is
going back and forth to power save mode like it does when you unplug the
displayport cable.

This started last week. I run the software updater last week.

I have seen old workarounds that say you should press ctr + alt + F6 but
it does not fix the problem.

Turning of the hdmi screen in displays does not fix the problem.

Unplugging hdmi screen does not fix the problem

Unplugging and Plugin the displayport does not fix the problem.

The short time the displayport screen is on it flickers and there is
some static noise in a few pixels.

I will attach more  information if you request it.
