Minecraft World Selection Grub Theme

Wowie, another Minecraft grub theme! But this time it's in the style of the singleplayer world selection menu, which makes a little more sense than selecting your operating system from the main menu. There are also icons now! Isn't that great? And even better, they also include the descriptive text below each boot option!

Installation

• Clone this repository

  git clone https://github.com/Lxtharia/minegrub-world-sel-theme.git
  

• [Optional]: download the background matching your screen size from here
  • And copy it to minegrub-world-selection/background.png
• Copy the folder to your boot partition

  cd ./minegrub-world-sel-theme
  sudo cp -ruv ./minegrub-world-selection /boot/grub/themes/
  

• Change/add this line in your /etc/default/grub:

  GRUB_THEME=/boot/grub/themes/minegrub-world-selection/theme.txt
  

• Update your live grub config by running

  sudo grub-mkconfig -o /boot/grub/grub.cfg
  

NixOS flake

Minimal example

# flake.nix
{
  inputs.minegrub-world-sel-theme.url = "github:Lxtharia/minegrub-world-sel-theme";
  # ...

  outputs = {nixpkgs, ...} @ inputs: {
    nixosConfigurations.HOSTNAME = nixpkgs.lib.nixosSystem {
      modules = [
        ./configuration.nix
        inputs.minegrub-world-sel-theme.nixosModules.default
      ];
    };
  }
}

# configuration.nix
{ pkgs, ... }: {

  boot.loader.grub = {
    minegrub-world-sel = {
      enable = true;
      customIcons = [{
        name = "nixos";
        lineTop = "NixOS (23/11/2023, 23:03)";
        lineBottom = "Survival Mode, No Cheats, Version: 23.11";
        # Icon: you can use an icon from the remote repo, or load from a local file
        imgName = "nixos";
        # customImg = builtins.path {
        #   path = ./nixos-logo.png;
        #   name = "nixos-img";
        # };
      }];
    };
  };

}

Icons

GRUB can add icons to each entry, based on the --class properties of a menuentry. This theme makes use of this to have each entry have its own icon and world description! Example:

# grub will try to use /boot/grub/themes/minegrub-world-selection/icons/arch.png as the icon and falls back on  gnu-linux.png,  gnu.png  and  os.png
menuentry 'Arch Linux' --class arch --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-somefunnyuuid' {
  ...
}

Setting icons for entries like Uefi Settings

If you want items like Uefi Settings to have an icon, you need to add --class uefi manually to the menuentry line in /boot/grub/grub.cfg:

menuentry "Uefi Settings" --class uefi ...

In this case you can put it in /etc/grub.d/30_uefi-firmware so it doesn't get overwritten when you regenerate your grub.cfg :>
