SUMMARY I've got two monitors on a NVidia adapter. Left one is primary. The last two nights I didn't hibernate or shutdown the computer, but only powered off the two monitors. Yesterday, when powering on the monitors, all open Windows were moved to the left screen. Today, the whole screen configuration of the right screen was gone: - different background - different panel Judging from the mess in .config/plasmashellrc and the count badges in the "Add Widgets ..." popup, the screen configuration still exists, but isn't applied anymore because plasma fails to recognize the screen. It took me over an hour, a reboot and eventually setting up everything again, because it is impossible to convince kscreen that screen X is the same one as yesterday, and it is impossible to get back the apparently still existing screen configuration. I don't know how kscreen tries to recognize monitors, but that obviously is flawed. And in any case, those ghostly screen configuration should be available somewhere to help people to work around the mess kscreen creates. Those lost configurations I encounter rather often, but usually after a reboot - not simply after power off/on of just two monitors.
Hey Arne, I came here looking for a solution for a similar problem you're describing, and I suspect that what was described in https://bugs.kde.org/show_bug.cgi?id=376341#c30 is my problem. Unfortunately my monitors do not have the ability to disable automatic input switching, so I'm stuck. Maybe if you can confirm it's a thing, and more people can confirm it's a thing, a fix could be developed?
I am also having the same issue. Dual monitor configuration with the left one as primary. The secondary seems to be the one that keeps losing the configuration. Different background and panel configuration. My only workaround right now is to turn off power management for the monitors so they don't go to sleep.
The issue with windows moving should have been fixed with KWin in Plasma 5.26. For the other issues, can we ask you to please check if this is still an issue with Plasma 5.26? If it is, please change the status to CONFIRMED when replying. If not, or if you can't because you no longer use this setup, you can change the status to RESOLVED WORKSFORME. Thanks a lot!
