xorg.conf
Just opinion on KDE display switcher: https://www.reddit.com/r/kde/comments/96fwv9/plasma_513_awkward_switch_displays_behavior/ Workaround: In the System Settings -> Background Services -> Startup and Shutdown. I unticked KScreen 2, this stops it from starting automatically. You're configuring via Xorg.conf, then disable KScreen. So what? It must a bug because there is no external screen. Please explain why it can't detect external screen connection properly? Please provide the output of xrandr -q Didn't you explicitly configure your xorg.conf to have two Screens? Screen 0: minimum 8 x 8, current 2280 x 1920, maximum 16384 x 16384 DVI-I-0 disconnected (normal left inverted right x axis y axis) DVI-I-1 connected primary 1200x1920+1080+0 left (normal left inverted right x axis y axis) 518mm x 324mm 1920x1200 59.95*+ 1920x1080 60.00 1680x1050 59.95 1600x1200 60.00 1280x1024 60.02 1280x960 60.00 1024x768 60.00 800x600 60.32 640x480 59.94 HDMI-0 disconnected (normal left inverted right x axis y axis) DP-0 disconnected (normal left inverted right x axis y axis) DVI-D-0 connected 1080x1920+0+0 right (normal left inverted right x axis y axis) 598mm x 336mm 1920x1080 60.00*+ 1680x1050 59.95 1600x1200 60.00 1600x900 60.00 1440x900 59.89 1400x1050 59.98 1280x1024 60.02 1280x960 60.00 1280x800 59.81 1024x768 70.07 60.00 800x600 72.19 60.32 56.25 640x480 72.81 59.94 DP-1 disconnected (normal left inverted right x axis y axis) Yes, I did explicitly configure xorg.conf to have two Screens. That shows two screens. Given Xorg things there are two screens and you explicitly told it to, what exactly is the bug? Obviously these screens are permanently connected. Dialog should be shown only when new external screen is connected. RFC patch: https://phabricator.kde.org/D22803 That patch landed; did/would it fix this bug? Assuming so. Please re-open if it's still a problem in Plasma 5.22 or newer. |
Created attachment 121761 [details] Screenshot Since KDE display configuration is broken (and by other reasons) it is better to configure displays via xorg.conf. But after that KDE starts to display bogus dialog asking to change display mode. How to disable it completely and tell KDE to not try to reconfigure displays?
