available again). Maybe related to https://bugs.kde.org/show_bug.cgi?id=501971
STEPS TO REPRODUCE

2. Use different input on the display
2. Switch display to PC and wake the system (or maybe wake PC first and then
switch)
OR
1. Wake up from suspend
2. Turn display on
3. See alternative display configuration get enabled and disabled, when the
screen is finally available
OBSERVED RESULT
