SUMMARY When I set a hotkey combination in the Hotkey settings to manually turn off the monitor and then try to use those hotkeys, the monitor turns off, but only for a couple of seconds, and then turns back on. STEPS TO REPRODUCE 1. I open System settings, then select Keyboard, Hotkeys. 2. I select Power Management, then select the Turn off monitor option and set the desired key combination. 3. I click Apply, then try to use this key combination to turn off the monitor. OBSERVED RESULT The monitor turns off for only a couple of seconds and then turns on again... EXPECTED RESULT The monitor should turn off after pressing the specified hot keys and should turn on from the keyboard or mouse usage... SOFTWARE/OS VERSIONS Linux/KDE Plasma: openSUSE Tumbleweed KDE KDE Plasma Version: 6.3.5 KDE Frameworks Version: 6.14.0 Qt Version: 6.9.0 ADDITIONAL INFORMATION I see this behavior of the System Settings on my laptop and desktop at the same time. Both computers have the same version of OpenSUSE installed.

Or an external screen?

I have now checked the system operation on a laptop (built-in screen) and a desktop, in both cases the X11 graphics platform was used, the result was the same, as described before, but if I logged into the system under Wayland on both computers, then everything works fine, the screen turns off with the assigned keys! I am still working on X11, and apparently many people still remain on it for some reasons... Therefore, this system error is still relevant.
Ok, I guess it's X11-only.
Can reproduce on X11.

Cannot reproduce on Wayland with ctrl+ä. Which shortcut are you using?

Let's not mix up problems here. The issues on Wayland are almost certainly bug 493879 - a workaround for the output missing - while the X11 problem is something else.
