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

services.logind = {
  lidSwitchExternalPower = "ignore";
  lidSwitchDocked = "ignore";
};

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
