NixOS Grub Themes

This is a flake of Grub themes to use with NixOS. Each of the directories in themes gives a theme which is usable.

It is simple to add themes to this flake! Just add a directory to themes and put a default.nix file in there. Feel free to submit a pull request to add themes.

To use one, set the boot.loader.grub.theme option in your NixOS configuration to the desired derivation generated by this flake.

Installation with NixOS:

First you will have to add this repo to your flake.nix file as a new input.

# flake.nix
{
  description = "NixOS configuration";

  inputs = {
    ...
    # Add nixos-grub-themes to your inputs ...
    nixos-grub-themes.url = "github:jeslie0/nixos-grub-themes";
  };

  outputs = inputs@{ nixpkgs, ... }: {
    nixosConfigurations = {
      my_host = nixpkgs.lib.nixosSystem {
        system = "x86_64-linux";
        specialArgs = { inherit inputs; };  # pass the inputs into the configuration module
        modules = [
          ./configuration.nix
        ];
      };
    };
  };
}

After that, you can configure the theme as shown below. In this example it is inside the configuration.nix file but it can be any file you choose.

# configuration.nix
{ inputs, config, pkgs, lib, ... }:
{
  boot.loader.grub = {
    ...  # your existing config
    theme = inputs.nixos-grub-themes.packages.${pkgs.system}.nixos;
  };
}
