Description rajil.s 2024-05-05 05:10:50 UTC

SUMMARY

Plasma does not remember the position of left and right monitors. Every time i go from 1 monitor to 2 monitors in 'Display Configuration' it place my left screen on the right of current screen. 

STEPS TO REPRODUCE
1. Have two physical monitors, but have only 1 enabled.
2. Enable the 2nd monitor in "Display Configuration"
3. It places it on the right. Drag the monitor to be the left screen
4. Disable 2nd monitor
5. Enable second monitor. It again puts it on the right.

OBSERVED RESULT
Second monitor always comes out on the right

EXPECTED RESULT

System should remember that the monitor was set to left initially. And so it should come out on the left of the current screen.

Xaver, could this be the recently-fixed issue where it would inappropriately fall back to the X11 settings?

No, this is internal to the KScreen GUI. It already has logic to remember this position, but it seems to be a bit buggy

kcm: remember position of disabled screens even after the KCM was closed

At least on Wayland, the position is remembered regardless of the enablement status,
so there's no reason not to remember is
