Description harle-quin 2024-03-08 18:19:54 UTC

SUMMARY
The 'Active screen follows mouse cursor' option has been removed from settings, but the internal default value is true (see kwin/src/kwin.kcfg). When activeMouseScreen==true separateScreenFocus does not work, so there should be some safeguard to ensure that activeMouseScreen is false when the user sets separateScreenFocus to true.


STEPS TO REPRODUCE
1. In settings -> Window Behavior -> Focus - check 'Separate screen focus'
2. In settings -> Shortcuts -> KWin - configure shortcut for 'Switch to Next Screen'
3. Use previously configures shortcut

OBSERVED RESULT
There will be a message that switching screen is not possible, because of configuration, but this configuration can't be changed anymore (activeMouseScreen).

EXPECTED RESULT
Focus should be switch to other monitor.

For anyone looking for a temporary workaround, you can edit your $HOME/.config/kwinrc manually, find the [Windows] section, and add this line to it:
activeMouseScreen=true

Then log out and back in.

Thanks to harle-quin for mentioning the flag name in the OP :)

I have tried to add the key activeMouseScreen=true in the section [Windows] of file ~/.config/kwinrc and restart...without luck.

Make sure both SeparateScreenFocus and activeMouseScreen are set to true.

Sorry, I don't know how to post (if it's allowed) image...I have set both keys (see image).
Anyway, it's not a problem, I'll wait the fix of the bug...It's not too important one for me.

Thanks!

I'm sorry, my previous comment (#3) was incorrect: the line you should add is ActiveMouseScreen=false, not true (and make sure the A is capitalised). I just retested it after toggling this to true (doesn't work) then false again (which works).

I also confirm, with ActiveMouseScreen=false it works! Thanks!!
