On X11, in a multimonitor setting, Plasma doesn't remember the relative position of monitors. Every time I disconnect and connect again an external monitor, I have to open Display Configuration and rearrange my monitors to reflect their physical position on my desktop. SOFTWARE/OS VERSIONS Linux: Manjaro, Linux 6.6.32-1 KDE Plasma Version: 6.0.5 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.1
Possibly I was mislead by a different "issue": in the Display Configuration plasmoid, the behavior of "Extend to left" and "Extend to right" buttons is inverted with respect to Plasma 5. Thus, every time I select "Extend to right", my laptop monitor is placed to the left of my external monitor.
