Bug ID: 413663
Summary: [Wayland] Screens often reversed position after
suspend or boot
Product: KScreen
Version: 5.17.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: common
Assignee: kscreen-bugs-n...@kde.org
Reporter: t...@r.je

screenshot of display configuration system settings
SUMMARY
I have two monitors, both the same make/model which may be why detection is
intermittent, and the positioning seems completely arbitrary.
In kscreen I have set DP-3 to be on the left and DP-2 to be on the right with
DP-2 as my primary display (though this doesn't seem to be an option in
Wayland).
Intermittently, when booting or when resuming from suspend the order is
reversed: DP-3 is positioned on the right and DP-2 is positioned on the left. I
have to then manually open kscreen and reposition them.
It does not happen every time which makes me think it might be to do with which
one turns on/is detected first.
I created a new account in case it was old kscreen settings from my old X login
and it happens even if I have never logged into X on this account.
It does not happen in Xorg, only Wayland.
STEPS TO REPRODUCE
1. Configure the screens to be positioned left/right
2. Suspend/resume or reboot
OBSERVED RESULT
The screens frequently (~50% of the time) get switched.
EXPECTED RESULT
The configuration should be maintained through reboots and suspend/resume
cycles.
