Description André Fettouhi 2023-02-16 13:45:15 UTC 
Ever since Plasma 5.25 my dual monitor setup has been broken. I have two screens, one is 1080p (75 Hz) and the other is 1440p (144 Hz). My screens go to sleep after 15 minutes but when that happens only my 1080p wakes up when I move the mouse etc. Then my setup goes haywire and I have to set it up again. Before 5.25 everything worked fine and I haven't changed anything in my setup. This is under X11 btw. Monitors are connected via DisplayPort, using a 1080 GTX Nvidia card with latest stable driver.


STEPS TO REPRODUCE
1. Let dual monitor go to sleep
2. Wake them up
3. 

OBSERVED RESULT
Only one screen reactivates, other stays black.

EXPECTED RESULT
Both should wake up and retain desktop settings and widgets.
