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

You can override the package through .override or .overrideAttrs. This is easily achievable through NixOS or 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

(pkgs.hyprland.override { # or inputs.hyprland.packages.${pkgs.system}.hyprland
  enableXWayland = true;
  hidpiXWayland = false;
  nvidiaPatches = false;
})

NixOS & HM modules

programs.hyprland = { # or wayland.windowManager.hyprland
  enable = true;
  xwayland = {
    enable = true;
    hidpi = false;
  };
  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

The hyprland-hidpi Nix package includes a patched wlroots that can render HiDPI XWayland windows.

In order to enable HiDPI when using the NixOS or Home Manager modules, you can set programs.hyprland.xwayland.hidpi = true, or wayland.windowManager.hyprland.xwayland.hidpi = true, respectively.

Now that the required package to achieve HiDPI is installed, an XWayland instruction is needed to set the scale:

exec-once = xprop -root -f _XWAYLAND_GLOBAL_OUTPUT_SCALE 32c -set _XWAYLAND_GLOBAL_OUTPUT_SCALE 2

This will make XWayland programs look as if they were unscaled. To fix this, you have to set different environment variables to make the specific toolkits render at the proper scaling. For example, add this to your hyprland.conf:

env = GDK_SCALE,2
env = XCURSOR_SIZE,48

{{< hint >}} The GDK_SCALE environment variable won't conflict with Wayland-native GTK programs. {{< /hint >}}

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

$ 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.
