Minegrub

A Grub Theme in the style of Minecraft!

Installation

Note: grub vs grub2

If you have a /boot/grub2 folder instead of a /boot/grub folder , you need to adjust the file paths mentioned here and in the minegrub-update.service file

Also if you're not sure, run grub-mkconfig -V to check if you have grub version 2 (you should have)

Manually

Clone this repository

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

(optional) Choose a background

./choose-background.sh  # or just copy a custom image to minegrub/background.png

If you want to use the update script, copy an arbitrary number of images you would like to use to minegrub/backgrounds/. You can find some options in background_options/ but you can also use your own images.
If you do not want to use the update script or if you always want to use the same background, you can use ./choose-background.sh or just copy a custom image to minegrub/background.png
Copy the folder to your boot partition: (for your interest: -ruv = recursive, update, verbose)

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

Open /etc/default/grub with your text editor and change/uncomment this line:

GRUB_THEME=/boot/grub/themes/minegrub/theme.txt

Update your live grub config by running

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

You're good to go!
Check out the Configuration section if you want to auto-update the splash text, the background and the packages display after every boot

Using the installation script

Run the installation script as root and at your own risk (It's run as sudo after all)

sudo ./install_theme.sh

This will help you to install the theme, the systemd service and enable the console background
It also lets you choose a background if you don't want to randomize it

NixOS module (flake)

This is a minimal example

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

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

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

  boot.loader.grub = {
    minegrub-theme = {
      enable = true;
      splash = "100% Flakes!";
      background = "background_options/1.8  - [Classic Minecraft].png";
      boot-options-count = 4;
    };
    # ...
  };
}

Configuration

Adjusting for a different amount of boot options:

If you have more or less than 4 boot options, the buttons will overlap with the bottom bar (the one saying "Options" and "Console")
To move that bar down and fix this, all you need to do is edit this line in the theme.txt: /boot/grub/themes/minegrub/theme.txt
- (You can also edit the file in the cloned repository so you don't overwrite it again when you update the theme at some point (via a cp -r))
The formula and some precalculated values (for 2,3,4,5... boot options) are in the theme.txt, so you should be able to easily change it to the correct value.

Updating splash text, background and "x Packages Installed" text after every boot!

The update_theme.py script chooses a random line from assets/splashes.txt and generates and replaces the logo.png which holds the splash text, as well as updates the amount of packages currently installed. It also randomly chooses a file from backgrounds/ (ignoring hidden files beginning with a dot) as the background image.

Make sure fastfetch or neofetch is installed
Make sure Python 3 (or an equivalent) and the Pillow python package are installed
- Install Pillow either with the python-pillow package from the AUR or with sudo -H pip3 install pillow
- It's important to use sudo -H, because it needs to be available for the root user
To add new splash texts simply edit ./minegrub/assets/splashes.txt and add them to the file.
Put all backgrounds you want to randomly choose from in ./minegrub/backgrounds/. Hidden files (i.e. filenames beginning with a dot) will be ignored. You can also add your own images.
If you want to get a specific splash and/or background for the next boot, run python update_theme.py [BACKGROUND_FILE [SPLASH]], e.g. python update_theme.py 'backgrounds/1.15 - [Buzzy Bees].png' 'Splashing!'
- Empty string parameters will be replaced by a random choice, e.g. python update_theme.py '' 'Splashing!' for a random background and the splash Splashing!.

Update splash and "Packages Installed"...

...manually

Just run python /boot/grub/themes/minegrub/update_theme.py (from anywhere) after boot using whatever method works for you

...with init-d (SysVinit)

Just copy the ./minegrub-SysVinit.sh under /etc/init.d as minecraft-grub then run update-rc.d minecraft-grub defaults as root privileges:

sudo cp -v "./minegrub-SysVinit.sh" "/etc/init.d/minecraft-grub"
sudo chmod u+x "/etc/init.d/minecraft-grub" # Just to be sure the permissions are set correctly.
sudo update-rc.d minecraft-grub defaults

...with systemd

Edit ./minegrub-update.service to use /boot/grub2/ on line 5 if applicable
Copy ./minegrub-update.service to /etc/systemd/system
Enable the service: systemctl enable minegrub-update.service
If it's not updating after rebooting (it won't update on the first reboot because it updates after you boot into your system), check systemctl status minegrub-update.service for any errors (for example if pillow isn't installed in the correct scope)

Setting the console background

When in grub, pressing 'c' opens the grub console. If you want that console to have a background you can specify GRUB_BACKGROUND=<path> in /etc/defaults/grub

Though this doesn't work if a theme is set, so you first need to change a line in a grub file. This can be done by running this pretty looking sed command:

# Create a backup of the file first
cp /etc/grub.d/00_header ./00_header.bak
# replace the elif in that line with an fi; if
sed --in-place -E 's/(.*)elif(.*"x\$GRUB_BACKGROUND" != x ] && [ -f "\$GRUB_BACKGROUND" ].*)/\1fi; if\2/' /etc/grub.d/00_header

Now you can set

GRUB_BACKGROUND="/boot/grub/themes/minegrub/dirt.png"

And don't forget to regenerate the grub.cfg :)

Notes:

the GRUB_TIMEOUT_STYLE in the defaults/grub file should be set to menu, so it immediately shows the menu (else you would need to press ESC and you dont want that)
