hyprland-wiki/pages/Nix/Options & Overrides.md

You can override the package through `.override` or `.overrideAttrs`. This
is easily achievable on [NixOS](../Hyprland-on-NixOS) or
[Home Manager](../Hyprland-on-Home-Manager).

## Package options

These are the default options that the Hyprland package is built with. These
can be changed by setting the appropriate option to `true`/`false`.

### Package

```nix
(pkgs.hyprland.override { # or inputs.hyprland.packages.${pkgs.system}.hyprland
  enableXWayland = true;
  enableNvidiaPatches = false;
})
```

### NixOS & HM modules

```nix
programs.hyprland = { # or wayland.windowManager.hyprland
  enable = true;
  xwayland.enable = true;
  enableNvidiaPatches = false;
};
```

## Options descriptions

### XWayland

XWayland is enabled by default in the Nix package. You can disable it either
in the package itself, or through the module options.

### XWayland HiDPI

See [XWayland](../../Configuring/XWayland).

### Nvidia Patches

Nvidia is notorious for not working by default with wlroots. That's why we
patch wlroots.

In the NixOS and Home Manager modules, you can enable the
Nvidia patches using `programs.hyprland.enableNvidiaPatches` and
`wayland.windowManager.hyprland.enableNvidiaPatches`, respectively.

## Using Nix repl

If you're using Nix (and not NixOS or Home Manager) and you want to override,
you can do it like this

```nix
$ nix repl
nix-repl> :lf "github:hyprwm/Hyprland"
nix-repl> :bl outputs.packages.x86_64-linux.hyprland.override {enableNvidiaPatches = true;} # option = value
```

Then you can run Hyprland from the built path.
