Description Claudius Ellsel 2021-01-28 19:01:05 UTC 
SUMMARY
On the current Plasma Beta (5.20.90) I noticed that the screen doesn't seem to turn off when I lock it (shortcut Meta + L). Currently only tested on Wayland.

STEPS TO REPRODUCE
1. Start a session
2. Lock the screen
3. Wait a short amount of time for the displays to turn off

OBSERVED RESULT
The displays stay on

EXPECTED RESULT
The displays are turned off

I am rather sure this is a regression (although I haven't used Tumbleweed Wayland that often). Setting the keyword.

Just tested on X11 and I have a similar experience there. Waited about a minute but nothing changed. However, I am not entirely sure anymore how long it used to take the screens to turn off after locking the screen.

Hello, my screen seems to have turned off after ten minutes.
I'll text this further later on, but can you check if waiting for more than a few minutes works on your machine?

Alright. I am marking this as waitingforinfo, as everything might be working completely fine. The instance where the screen was still on after I was afk for about 30 Minutes might have been caused by my mouse slightly moving and thus turning the screen on again. I'll have to try again properly, and probably it will also work for me, so false alarm.

On a second test it worked for me, so most likely a false alarm.
