Description Christophe PEREZ 2024-12-21 22:52:29 UTC 
I'll explain it very simply.

- enable power saving to go to sleep after 5 minutes
- enable power saving so that the screen turns off after 2 minutes
- put in /etc/elogind/system-sleep/000pre_suspend
	#!/bin/bash
	case $1/$2 in
		pre/*) exit 1 ;;
	esac

- wait 2 minutes, the screen turns off
- wait 3 minutes more, and the screen turns back on because of the suspend failure.

What makes the screen turn back on? How can I make it not happen?
Before using plasma 6, I didn't have this problem.
It's really very boring how it works.
