title: Hyprland on NixOS
---
The NixOS module enables critical components needed to run Hyprland properly,
such as: polkit,
[xdg-desktop-portal-hyprland](https://github.com/hyprwm/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](https://search.nixos.org/options?channel=unstable&from=0&size=50&sort=relevance&type=packages&query=hyprland).
{{< 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,Flake Package, No Flakes (with flake-compat)" >}}
{{< tab "Nixpkgs" >}}
```nix
# configuration.nix
{pkgs, ...}: {
programs.hyprland.enable = true;
}
```
This will use the Hyprland version that Nixpkgs has.
{{< /tab >}}
{{< tab "Flake package" >}}
{{< callout >}}
Please enable [Cachix](../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:
```nix
# flake.nix
{
inputs.hyprland.url = "github:hyprwm/Hyprland";
# ...
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.${pkgs.system}.hyprland;
};
}
```
Don't forget to change the `HOSTNAME` to your actual hostname!
{{< callout >}}
If you start experiencing lag and FPS drops in games or programs like Blender on
**stable** NixOS when using the Hyprland flake, it most likely is a `mesa`
version mismatch between your system and Hyprland.
You can fix this issue by using `mesa` from Hyprland's `nixpkgs` input:
```nix
{pkgs, inputs, ...}: let
pkgs-unstable = inputs.hyprland.inputs.nixpkgs.legacyPackages.${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;
};
}
```

## Fixing problems with themes
If your themes for mouse cursor, icons or windows don't load correctly, see the
relevant section in [Hyprland on Home Manager](../Hyprland-on-Home-Manager).
