You can override the package through `.override` or `.overrideAttrs`. This is
easily achievable through [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;
nvidiaPatches = false;
})
```
### NixOS & HM modules
```nix
programs.hyprland = { # or wayland.windowManager.hyprland
enable = true;
xwayland = {
enable = true;
};
nvidiaPatches = 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.nvidiaPatches` and `wayland.windowManager.hyprland.nvidiaPatches`,
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
```console
$ nix repl
nix-repl> :lf "github:hyprwm/Hyprland"
nix-repl> :bl outputs.packages.x86_64-linux.hyprland.override {nvidiaPatches = true;} # option = value
```
Then you can run Hyprland from the built path.
