KDE Plasma is a desktop environment that aims to be simple by default, powerful when needed.

Installing KDE Plasma

To use KDE Plasma, add this to your configuration.nix:

services.xserver.enable = true;
services.xserver.displayManager.sddm.enable = true;
services.xserver.desktopManager.plasma5.enable = true;

Excluding some KDE Plasma applications from the default install

Not all applications that come pre-installed with the KDE Plasma desktop environment are desirable for everyone to have on their machines. There's a way to edit configuration.nix to exclude these kinds of packages, for example as follows:

services.xserver.desktopManager.plasma5.excludePackages = with pkgs.libsForQt5; [
  elisa
  gwenview
  okular
  oxygen
  khelpcenter
  konsole
  plasma-browser-integration
  print-manager
];

Troubleshoots

Qt/KDE applications segfault on start

This is caused by a stale QML cache (see this issue). A dirty way to fix this is by running on a terminal the following command:

find ${XDG_CACHE_HOME:-$HOME/.cache}/**/qmlcache -type f -delete

GTK themes are not applied in Wayland applications

Add to your configuration.nix the following line:

programs.dconf.enable = true;

(See this issue)

When you see the message grantlee.template: "Plugin library 'kde_grantlee_plugin' not found." and/or kmail does shows only empty message then add to your configuration.nix the following line:

environment.sessionVariables = {
  NIX_PROFILES = "${pkgs.lib.concatStringsSep " " (pkgs.lib.reverseList config.environment.profiles)}";
};
