Fix external display turning off when closing laptop lid with KDE and Wayland
I’ve been using NixOS with KDE Plasma 6.2 and Wayland lately, one weird issue I was running into was not being able to close the laptop lid when I connected to my thunderbolt dock.
I tested the following Nix configuration with no luck
1services.logind = {
2 lidSwitchExternalPower = "ignore";
3 lidSwitchDocked = "ignore";
4};
The issue turned out to be caused by KWin, the fix in my case was
- Log out of KDE (Your changes might be overwritten by KDE on log out, so better do this without KDE running)
- Log in using a terminal session
- Rename the kwinoutputconfig.json file
mv .config/kwinoutputconfig.json .config/kwinoutputconfig.json.org - Log back in to KDE
You will of course lose your monitor alignment and other configurations
