2nd monitor disabled in KDE Plasma

Today when booting, my second monitor showed the following rather strange problem: It was on in the logon screen, normally showing a second logon screen, but as soon as I logon into KDE Plasma, the monitor gets disabled (light turns from blue to orange, “no signal”, standby). Sometimes I have hickups with the displays, and so far I have attributed them to the state of the NVidia driver (running a 3070).

Now, inside KDE Plasma, suddenly the monitor does not get recognized in the display configuration of Plasma. Well, I say “recognized”, the display seems to be there (selectable from the list of displays), however the graphic at the top where you can drag and drop displays to align them doesn’t show the second monitor. I fiddled around with the settings, and although I can toggle active and inactive on and off and “Apply”, the second monitor never gets used.

Afterwards, I’ve tried nvidia-settings, and in the same display where you can see visual representations of your monitor, the second monitor doesn’t get displayed as well! However, using the settings and activating the second monitor, I can “fix” the problem. So via the NVidia tool I can at least work around it.

This is the log of the last system update I did (the day before yesterday, so I already booted into the system that is this way yesterday):

Nothing jumps out as a possible cause, but I’m not an expert in the linux graphics and display server.

This package is related to display configuration.
Nevertheless, if the issue persists, I recommend deleting the current kscreenrc configuration file, to reset local config.

This issue is reported recently from other users.
Plasma upgrades often need this reset.

Thank you for the information. I had looked up the issue, but seem to not have found the right words.

I removed the .local/share/kscreen directory and rebooted, and the monitor reappeared in the configuration.
