Same here with archlinux kscreen 5.4.1-1. When I unplug the monitor, new launched applications still go to the external monitor, making the desktop unusable. Same on Plasma 5.4.2 on Manjaro. I did the following tests: - Dock the notebook when already on (two monitors attached to docking station) I obtained these different results: 1. No external monitors detected 2a. External monitor detected but disabled and display "No resolutions available", so that it's not possible to activate them 2b. As 2a but a third non existent monitor is detected. After I tried to logout, in the login screen all the three monitors are active, when I login all the three monitor are disabled. Also the notebook one. To solve I login via a shell and removed all the kscreen config files. I tried to login again and it got stuck during the KDE/Plasma loading phase (still in the splash screen). Then I rebooted and the three monitor are detected correctly automatically. This will last until I'll put my notebook to sleep where all the configurations files will be screwed again. Same here, attaching dmesg output in case it's useful for anything...

So this is maybe not bug in KDE/Plasma? Same problem here on up-to-date Arch Linux and I confirm the patch does not solve it. Fixed for me in Plasma 5.8.2. Thanks for confirmation! |
