Bug ID: 475829
Summary: Displays never turn off in wayland session
Classification: Plasma
Product: kwin
Version: 5.27.8
Platform: Other
OS: Other
Status: REPORTED
Severity: grave
Priority: NOR
Component: xrandr

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
STEPS TO REPRODUCE
1. Start Wayland session
2. Use display that automatically disconnects it output when no signal is
detected
3. Leave system idle and wait 10 minutes for it to try to dim screens
OBSERVED RESULT
Screens turn off for a brief moment, but then immediately light up again.
Process repeats every 10 minutes.
This is due to screen 'disconnecting' itself from graphics card output. On
Windows you could hear 'device disconnected' sound when screen goes dark.
There's no way do disable this behavior in Monitor menu.
EXPECTED RESULT
Screens should stay dark when there's no user input
