Created attachment 188648 [details] Display Configuration page showing the issue SUMMARY The Display Configuration page of the System Settings does not have a "Reset to Defaults" button, so if the config gets messed up somehow you might need to find the right file and edit it by hand. I don't know what I did, but this happened to me. The coordinates for one monitor were for some reason way too large and I couldn't drag it back using the Edit Arrangement functionality anymore. See attached screenshot. Took some poking and asking around to find ~/.config/kwinoutputconfig.json so I could edit the coordinates to reasonable values again. STEPS TO REPRODUCE I don't know how it happened, but I somehow ended up with "position": { "x": 2147482367, "y": 2147483647 } for one output in ~/.config/kwinoutputconfig.json OBSERVED RESULT There's no way to get the output into a usable state anymore using the config dialog. EXPECTED RESULT There should be a "Reset to Defaults" button that puts everything into a reasonable position again. SOFTWARE/OS VERSIONS KDE Plasma Version: 6.5.4 KDE Frameworks Version: 6.20.0 Qt Version: 6.10.1
If there's any way you can figure out how you got the positions in such state, let us know. You can create a separate bug report for it. Thanks!
Someone has reported the problem in bug 507702 Note: There is already a "Reset" button to revert changes made in the UI that haven't been applied The feature would be to reset the display config to a known good state. I'm marking this feature request confirmed, to pass it along to the kcm maintainers for consideration. Thanks!
