SUMMARY When logging in selecting Wayland, panels and desktops are attached to the wrong monitors/displays. STEPS TO REPRODUCE 1. Boot ArchLinux, select Wayland. 2. Observe the panels and desktops disrupted. OBSERVED RESULT Desktops and panels are attached to the wrong monitor. EXPECTED RESULT Panels and desktops remain attached to the monitors I have set up for them regardless of desktop compositor. As it used to be prior to the Plasma 6 upgrade. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.0.2 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 Kernel Version: 6.8.1-zen1-1-zen (64-bit) Graphics Platform: X11 Processors: 12 × Intel® Core™ i7-8700K CPU @ 3.70GHz Memory: 15.5 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 1070/PCIe/SSE2 ADDITIONAL INFORMATION Using 3 monitors. This started happening after upgrading to Plasma 6. Something similar to this had happened in the past but it had been solved, it was possible to change between x11 and Wayland while keeping the same desktops and panels on the right monitors. If I logoff Wayland and go back to X11 the panels and desktops are attached to the correct monitors. If I correct the panels and desktops for Wayland and attach them the way they should go, then going back to x11 will have the panels all wrong.
I have two monitors, a 1440p monitor and a vertical 1080p monitor on the left. Any panels I place on the left (vertical, secondary) monitor re-appear on the right (horizontal, primary) monitor after a reboot. It happens if the panel is set to fit width or full width, and was not happening with the same monitor configuration in Plasma 5 on Debian. SYSTEM INFORMATION: Operating System: Fedora Linux 40 KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.1.0 Qt Version: 6.7.0 Kernel Version: 6.8.7-300.fc40.x86_64 (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 7600 6-Core Processor Memory: 30.5 GiB of RAM Graphics Processor: AMD Radeon RX 6700 XT
Screen and panel data is stored differently on X11 and Wayland, so I'm afraid it's expected that the first time you log into a Wayland session, you'll have to redo them. After you've got the screen and panel settings configured to your liking in both X11 and Wayland sessions, nothing should change when you switch between them, though. Are you seeing something other than that in Plasma 6.1?
(In reply to Nate Graham from comment #2) > Are you seeing something other than that in Plasma 6.1? The issue was that they would reset on every reboot - even though I don't have an X11 session installed. I was needing to manually move the panel back over on every reboot, then power cycle the monitor, because the panel's Task Manager wouldn't update which monitor it was on. I can't find a patch note that says what commit fixed it - but it's no longer happening in KDE Plasma 6.1.4 / KDE Frameworks 6.5.0 .
Great, let's call it fixed in Plasma 6.1

(In reply to Nate Graham from comment #4) > Great, let's call it fixed in Plasma 6.1 Unfortunately, this bug seems to have returned in Plasma 6.2.5? I wasn't having the issue in 6.1 to 6.2.4, but it came back recently. No other changes to my hardware or panel setup since. I don't have the X11 desktop installed to compare with. SOFTWARE/OS VERSIONS Operating System: Fedora Linux 41 KDE Plasma Version: 6.2.5 KDE Frameworks Version: 6.9.0 Qt Version: 6.8.1 Kernel Version: 6.12.8-200.fc41.x86_64 (64-bit) Graphics Platform: Wayland HARDWARE INFORMATION: Processors: 12 × AMD Ryzen 5 7600 6-Core Processor Memory: 30.5 GB of RAM Graphics Processor: AMD Radeon RX 6700 XT
If it came back after a period of being fixed, it's likely a different issue. Can you open a new bug report for it?
