Tiago's Incredible Boot Screen (TIBS)

Tiago's Incredible Boot Screen (TIBS) is a (🚧 Work In Progress) boot animation program and display manager written in Rust. Designed to replace tools like Plymouth, SDDM, and GDM, TIBS delivers a smooth, modern boot experience by rendering animations with OpenGL.

Features

• Early Boot Animation:
  Provides a seamless and visually appealing boot screen right from the start of the boot process.

• Direct DRM Rendering:
  Uses DRM for direct screen output, bypassing traditional window managers to reduce latency and jank.

• OpenGL-Powered Graphics:
  Delivers high-quality, dynamic animations with hardware acceleration.

• Integrated Input Handling:
  Processes keyboard and mouse input using libinput, ensuring responsive control throughout the boot sequence.

• Scalable Cursor Rendering:
  Supports modern, vector-based cursor themes via the Hyprcursors library. Hyprcursors renders the cursor to a bitmap on demand, ensuring crisp visuals without the need for multiple bitmap sizes.

NixOS Integration

TIBS includes a built-in NixOS module for easy integration. To activate TIBS on NixOS, import the TIBS NixOS module from the flake and enable it in your configuration:

{
    # ...
    imports = [
        inputs.tibs.nixosModules.tibs
    ];
    tibs.enable = true;

    # IMPORTANT: Disable all display managers and Plymouth to avoid conflicts.
    services.displayManager.sddm.enable = false;
    services.displayManager.gdm.enable = false;
    services.displayManager.ly.enable = false;
    boot.plymouth.enable = false;

    # Include the appropriate graphics driver in the initramfs.
    # This might be different depending on your gpu and what
    # kind of driver your using
    # This is to prevent tibs from starting with a dummy driver
    # and then crashing when the real driver loads
    boot.initrd.kernelModules = [ "i915" ]; 
    boot.initrd.systemd.enable = true;

    # OpenGL is, of course, also required for tibs to work properly
    hardware.graphics = {
        enable = true;
        extraPackages = with pkgs; [
            intel-media-driver # LIBVA_DRIVER_NAME=iHD
            libvdpau-va-gl
        ];
    };

    # ...
}

This configuration launches TIBS as a systemd service immediately after the initramfs stage, providing an early boot animation and handling input and cursor rendering before the desktop environment takes over.

---

Usage

• Boot Process:
  TIBS runs as a systemd service early in the boot sequence. Its configuration ensures that it operates before any display manager is started, presenting a smooth boot animation.

• Customizing Animations & UI:
  Modify the assets within the designated assets directory to adjust animations, progress bars, logos, and other UI elements.

• Cursor Rendering:
  TIBS leverages the Hyprcursors format for scalable, vector-based cursor themes.
