SUMMARY The desktop layout is changed from "Desktop" to "Folder View" when I unplugged an external monitor. Later, if I try to change it back to "Desktop", it is not possible. Rebooting restores the "Desktop" layout back. STEPS TO REPRODUCE 1. Choose "Desktop" layout 2. Connect external monitor 3. Unplug external monitor 4. Go to Configure Desktop and Wallpaper and try changing layout OBSERVED RESULT Layout is changed for no reason after unplugging the external monitor. This was happening to me in the past in the other direction (when connecting a new monitor, it would, by default, show the desktop in folder view) but it was always possible to change the setting. Now, if you go to "Configure Desktop and Wallpaper" by right clicking on the desktop, the layout shows that is in "Folder View". When selecting "Desktop", a message saying that "layout changes must be applied before other changes can be made" is shown with an "Apply Now" button. This button does not work. Using the general "Apply" and "Ok" buttons also doesn't change the layout. EXPECTED RESULT Layout should never be changed under any event (apart from the settings menu). If "Desktop" layout is selected, all new additional screens should use that layout. Perhaps in the future it would also make sense to add an additional button like "Apply to All", that could change settings to all screens at once (layout, wallpaper, etc.). And, in any case, it should be possible to change the layout at any time, even if right now is changed automatically under some circumstances.

This is different to Bug 459368 because checking `journalctl -p err -b` nothing crashed here. Also, when I experience the other bag, the wallpaper dissapears and I only see a black background, with the rest of the elements still working (panel, kickoff, etc.)
Looks like it's 450068. There are some problems identifying outputs. *** This bug has been marked as a duplicate of bug 450068 ***
(In reply to Fushan Wen from comment #2) > Looks like it's 450068. There are some problems identifying outputs. But that other bug was reported in Plasma 5.24 and I only noticed this issue after upgrading to Plasma 5.26 Beta. So something else must have changed as well. But yeah, probably this will be fixed with the other changes.
There are other people reporting the same issue. Can you test if https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/1781 fixes this bug? The patch is in 5.25 but not in 5.26
It doesn't fix it for me.
Thank you for testing. Mark as reported now
I can confirm this happens in 5.26.2 too, but only in Wayland. No such problem in X11.

Ultimately this is caused by that issue. *** This bug has been marked as a duplicate of bug 450068 ***
