Hyprland on NixOS

The NixOS module enables critical components needed to run Hyprland properly, such as: polkit, xdg-desktop-portal-hyprland, graphics drivers, fonts, dconf, xwayland, and adding a proper Desktop Entry to your Display Manager.

Make sure to check out the options of the NixOS module.

{{< callout >}}

• (Required) NixOS Module: enables critical components needed to run Hyprland properly
• (Optional) Home-manager module: lets you declaratively configure Hyprland

{{< /callout >}}

{{< tabs items="Nixpkgs,Flakes,Nix stable (flake-compat)" >}}

{{< tab "Nixpkgs" >}}

# configuration.nix

{pkgs, ...}: {
  programs.hyprland.enable = true;
}

This will use the Hyprland version that Nixpkgs has.

{{< tab "Flake Package" >}}

{{< callout >}}

Please enable Cachix before using the flake package, so you don't have to compile Hyprland yourself.

{{< /callout >}}

In case you want to use the development version of Hyprland, you can add it like this:

# flake.nix

{
  inputs.hyprland.url = "git+https://github.com/hyprwm/Hyprland?submodules=1";
  # ...

  outputs = {nixpkgs, ...} @ inputs: {
    nixosConfigurations.HOSTNAME = nixpkgs.lib.nixosSystem {
      specialArgs = { inherit inputs; }; # this is the important part
      modules = [
        ./configuration.nix
      ];
    };
  };
}

# configuration.nix

{inputs, pkgs, ...}: {
  programs.hyprland = {
    enable = true;
    package = inputs.hyprland.packages.${pkgs.system}.hyprland;
  };
}

Don't forget to change the HOSTNAME to your actual hostname!

If you start experiencing lag and FPS drops in games or programs like Blender on stable NixOS when using the Hyprland flake, it most likely is a mesa version mismatch between your system and Hyprland.

You can fix this issue by using mesa from Hyprland's nixpkgs input:

{pkgs, inputs, ...}: let
  pkgs-unstable = inputs.hyprland.inputs.nixpkgs.legacyPackages.${pkgs.stdenv.hostPlatform.system};
in {
  hardware.opengl = {
    package = pkgs-unstable.mesa.drivers;

    # if you also want 32-bit support (e.g for Steam)
    driSupport32Bit = true;
    package32 = pkgs-unstable.pkgsi686Linux.mesa.drivers;
  };
}

For more details, see issue #5148.

Fixing problems with themes

If your themes for mouse cursors, icons or windows don't load correctly, see the relevant section in Hyprland on Home Manager.
