After a recent Tumbleweed update of 250+ files I have lost the ability to configure the Desktop settings on both displays. (Dual display set-up obviously.)
For example, I could previously set the Desktop wallpaper background on both displays. Now I can only do that on 1 display. The other display gets an un-changable black background and no response to right-mouse-click which should present a menu to change the display settings.
Try using the KDE Display and Monitor app to check/change the resolution of your display(s). If it is showing as correct, apply a different setting and then apply the correct setting. For me this survives until the next boot.
Same behaviour here. Works but does not survive reboot.
Same problem here
The QT bug link is here: https://bugreports.qt.io/browse/QTBUG-86604
As suggested on that bug, running
fixes the problem (for me) until next reboot.
Just came back to openSUSE after being elsewhere for a long time.
Looking to see if there is an update with this issue.
I have a laptop connected to a second monitor. I am trying to set it up so it only uses the second monitor and not the laptop screen as they are not side-by-side.
The primary desktop only shows my desktop icons, while the non-primary desktop shows the main panel. It didn’t matter which one I set as primary, it was missing the panel.
Duplicating makes both of them act as primary desktops (no panel) and the different screen size / resolution also effects it.
I am able to get the external monitor usable so long as I have them of them running, overlaping each other and running as mentioned
Since you mentioned that it doesn’t stick between reboots I set up a script and added that to autorun when I log in.
Set it by using System settings > Startup and Shutdown > Autostart > Add Login script > [add an executable file w/code below]]

Do you have any updates or tricks that may work?
Try the following: Go into background services in systemsettings5, deselect “Kscreen 2” and apply. Log out of Plasma and delete ~/.local/share/kscreen2/* and ~/.cache/* while Plasma is not running. From then you can use a startup xrandr script that should stick. Mine are in /etc/X11/xinit/xinitrc.d/. Arandr can be used to create such a script.
