Issue when setting Primary display in dual monitor setup

Hello everyone,

I have an issue with my “Primary” display the past three weeks, and I did not manage to find a solution on Reddit about it, so time to ask the forums. I asked Fedora forums and they advised me to post my issue here.

Basically around a month ago I wanted to do a fresh installation and did install Fedora 41 (KDE) from the beginning.

Once installed, upon the first reboot, I noticed something weird. My main monitor was not actually the “Primary” display. In the “Display Configuration” settings, which I did check if Fedora recognizes correctly the monitors and it does, my main monitor “LG” is not set as “Primary display” but the taskbar and main windows do open in this monitor. If I set it as the “Primary Display”, the taskbar and everything else shifts to the second monitor.

I did another reboot at some point, without connecting the second monitor, as it was the same case! My primary monitor did not have a taskbar or and files where missing for the Desktop.

I am not sure what type of information I should upload so please do tell me if you need any further information.

Install Fedora KDE version 40 or later.
I installed a bunch of different shells with different versions. In the end, I decided that I should try to install Fedora KDE Plasma not 42, not 41, but 40 versions. And everything worked out.

First thing is to upgrade to Fedora 42 and check if it fixes the problem as there were many multi-monitor fixes in recent versions of KDE.
…or maybe not as it seems the same version of KDE is available in Fedora 41 and 42:
