Screen Settings
SUMMARY
I've been having a problem with "Turn off screen" feature after around Plasma
6.1 update. It was definitely working for me during the Plasma 6 beta time
frame, I think it also works for 6.0.x. Now at 6.1.4 I still have a problem.
STEPS TO REPRODUCE
1. Enable Turn off screen and set it to 30 minutes and When locked: 1 minute
2. Lock the screen
3. Wait until the screen goes off and wait few more minutes
4. Move the mouse and/or press any button
OBSERVED RESULT
Screen does not turn on. Even more, if I force shutdown the PC and turn it on,
screen still does not turn on, it requires a power cycle by unplugging it from
the wall.
EXPECTED RESULT
Screen will turn on
