 == Installation ==
-To use KDE Plasma, add this to your configuration.nix:
+=== Plasma 5 ===
+{{file|/etc/nixos/configuration.nix|nix|<nowiki>
+{
+  services.xserver.enable = true;
+  services.xserver.displayManager.sddm.enable = true;
+  services.xserver.desktopManager.plasma5.enable = true;
+}
+</nowiki>}}
+=== Plasma 6 ===
+Available on the unstable channel.
+{{file|/etc/nixos/configuration.nix|nix|<nowiki>
+{
+  services.xserver.enable = true;
+  services.displayManager.sddm.enable = true;
+  services.displayManager.sddm.wayland.enable = true;
+  services.desktopManager.plasma6.enable = true;
+}
+</nowiki>}}
+== Configuration ==
+=== Rootless X11 ===
+{{ic|sddm}} launches X11 as a root user by default. For better security, X11 should be run as a non-root user:
 <syntaxHighlight lang=nix>
-services.xserver.enable = true;
+services.xserver.displayManager.sddm.settings.General.DisplayServer = "x11-user";
-services.xserver.displayManager.sddm.enable = true;

+=== Excluding 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:
+Some optional packages that are installed by default can be excluded if they are not needed.
+==== Plasma 5 ====
+Optional packages: [https://github.com/NixOS/nixpkgs/blob/nixos-23.11/nixos/modules/services/x11/desktop-managers/plasma5.nix#L275-L284 plasma5.nix]

-== Troubleshoots ==
+For other themes, you may need the packages <code>libsForQt5.qt5ct</code> and <code>libsForQt5.qtstyleplugin-kvantum</code> and a symlink from <code>~/.config/Kvantum/</code> to your theme package. Here is an example using Arc-Dark and [[Home Manager]]. In the Home Manager configuration:
+<syntaxHighlight lang=nix>
+qt = {
+  enable = true;
+  platformTheme = "qtct";
+  style.name = "kvantum";
+};
+xdg.configFile = {

+  "Kvantum/kvantum.kvconfig".text = "[General]\ntheme=ArcDark";
+};

+For more details, see [https://discourse.nixos.org/t/guide-to-installing-qt-theme/35523/2 this] forum post.
+=== Default Wayland/X11 session ===
+==== Plasma 5 ====
+Plasma 5 runs on X11 by default. To launch a Wayland session by default:
