Primary monitor issue with libkscreen

[ComputerCraftr]

Describe your issue

There is currently an issue with libkscreen tracking the correct primary monitor on LXQt X11 session and it looks like this fork also contains some of the recent commits that may have changed xrandr behavior and introduced this issue:
https://invent.kde.org/plasma/libkscreen/-/merge_requests/265

I can try to build LXQt against this library and test it out later if that will help.

Ref: lxqt/lxqt-config#1184

Steps to reproduce

1. Configure LXQt config monitor to set the left as primary on startup
2. Reboot the computer

What did you expect?

Primary monitor is set correctly on reboot
