2.2 KiB

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

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

NixOS & HM modules

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

By default, the Nix package includes a patched wlroots that can render HiDPI XWayland windows.

In order to enable the functionality, you have to add:

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 export different environment variables to make the specific toolkits render at the proper scaling. For example

export GDK_SCALE=2
export XCURSOR_SIZE=48

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

Usually, there's no reason to disable this functionality, as it won't affect people who don't have HiDPI screens.

If you do insist on disabling it though (e.g. for adding your own patches to wlroots), you can do so by either using the hyprland-no-hidpi package, or by passing the hidpiXWayland = false; flag, the same way as disabling XWayland.

Nvidia Patches

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

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.
