# Xenlism Grub Theme for NixOS

## Installation

- Add this flake input to your **flake.nix** inputs
```nix
inputs = {
    grub-theme = {
      url = "git+https://gitea.homework.zip/shinya/Xenlism-Grub-Theme";
    };

    # More inputs ...
};
```

> [!IMPORTANT]
> If you switched your theme from systemd-boot to GRUB.
> You have to change your boot entry in UEFI or BIOS to GRUB.
> Because NixOS will otherwise still boot into systemd-boot.

- Then set GRUB theme to this package in your **configuration.nix** file
```nix
boot.loader.grub.theme = inputs.grub-theme.packages.x86_64-linux.xenlism-grub-theme-nixos-1080p;
```

> [!NOTE]
> Just a side note, in case you are using stylix or something that sets GRUB theme for you.
> You will maybe have to set this option with *lib.mkForce* to make it override other value.

- You can pick from list of distros and resolutions that are present in the [original repo](https://github.com/xenlism/Grub-themes/)

- To view all possible options run `nix flake show git+https://gitea.homework.zip/shinya/Xenlism-Grub-Theme --no-write-lock-file` this will display all possible packages to install

- To change theme you just have to change the package name in **configuration.nix** option like this:
```nix
boot.loader.grub.theme = inputs.grub-theme.packages.x86_64-linux.xenlism-grub-theme-[distribution]-[resolution];
```
