Qtile

Qtile is a full-featured, hackable tiling window manager written and configured in Python.

Enabling

To enable Qtile as your windowManager, set: services.xserver.windowManager.qtile.enable to true. For example:

/etc/nixos/configuration.nix

{ config, pkgs, ... }: 
  ...
  imports =
    [ # Include the results of the hardware scan.
      ./hardware-configuration.nix
      # For wayland support see the following config
      ./qtile.nix
    ];
  services.xserver.windowManager.qtile.enable = true;
  ...
}

/etc/nixos/qtile.nix

{ config, pkgs, lib, ... }:

{
  nixpkgs.overlays = [
  (self: super: {
    qtile-unwrapped = super.qtile-unwrapped.overrideAttrs(_: rec {
      postInstall = let
        qtileSession = ''
        [Desktop Entry]
        Name=Qtile Wayland
        Comment=Qtile on Wayland
        Exec=qtile start -b wayland
        Type=Application
        '';
        in
        ''
      mkdir -p $out/share/wayland-sessions
      echo "${qtileSession}" > $out/share/wayland-sessions/qtile.desktop
      '';
      passthru.providedSessions = [ "qtile" ];
    });
  })
];

services.xserver.displayManager.sessionPackages = [ pkgs.qtile-unwrapped ];
}

Please note, the wiki renders the greater than sign in the code above with the HTML code & followed by gt;. It needs to be the actual symbol ">" not the HTML code, ie. echo "${qtileSession}" > $out/share/wayland-sessions/qtile.desktop

Warning

The installation of Qtile leads to several of its dependencies being leaked in the user's PATH. This prevents the user from running a custom installation of python3 as Qtile will shadow the systemPackages in the PATH with its own python3.
