A Rust-based dynamic wallpaper engine for Wayland compositors that brings animated and interactive backgrounds to your desktop. WLRS supports shader-based visual effects, animated wallpapers, and a flexible layer system.

WLRS (wallpape-rs) is a dynamic wallpaper system for Wayland desktops. It uses a client-daemon architecture with WebGPU (wgpu) for high-performance rendering and Lua for scripting support.

• ✅ Seamless integration with Wayland compositors
• ✅ Multi-monitor support with per-monitor wallpaper configuration
• ✅ Static image wallpapers
• ✅ Solid color backgrounds
• ✅ Combined image + color backgrounds
• ✅ Shader-based visual effects
  • ✅ Wave distortion effect with dynamic animation
  • ✅ Glitch effect with customizable intensity
  • ✅ Gaussian blur effect with configurable radius
• ✅ Multiple effects can be layered and combined
• ✅ Configurable framerate for animations
• ✅ Simple and intuitive CLI interface
• 🚧 Lua scripting support for custom animations
• 🚧 Particle system effects

• Frontend - CLI tool for user interaction and control
• Daemon - Background service that renders wallpapers using wgpu
• Common - Shared code for IPC communication and wallpaper definitions

• Rust 1.70+
• Wayland libraries (libwayland-dev)
• OpenGL or Vulkan libraries (for GPU rendering)

git clone https://github.com/werdxz/wlrs.git
cd wlrs
cargo build --release

cargo install --path .

# Start the daemon service
wlrs-daemon

# List available wallpapers
wlrs list-wallpapers

# Set a wallpaper for all monitors
wlrs set-wallpaper "Wallpaper Name"

# Set wallpaper for a specific monitor
wlrs set-wallpaper "Wallpaper Name" --monitor "Monitor Name"

# Query active wallpapers
wlrs query

Each wallpaper has a simple directory structure:

├── assets/            # Images and other media files
│   ├── background.png
│   └── overlay.png
└── scripts/           # Optional Lua scripts
    └── animation.lua

• Shader effects:

  • wave: Creates a wavy distortion effect with customizable amplitude and frequency
    • Parameters: amplitude (0.0-1.0), frequency (0.0-1.0), speed (multiplier)
  • glitch: Creates a digital glitch/RGB split effect
    • Parameters: intensity (0.0-1.0), frequency (0.0-1.0)
  • gaussian: Applies a Gaussian blur
    • Parameters: radius (pixel radius of blur)
  • custom: Custom WGSL shader support (coming soon)

• Other effects:

  • particles: Particle system effects (coming soon)
  • image: Static image overlay

1. Create a directory for your wallpaper with the structure shown above
2. Create a manifest.toml file with your wallpaper configuration
3. Add your images to the assets/ directory
4. Add effects as needed in the manifest
5. Place the wallpaper in ~/.local/share/wlrs/wallpapers/ or use the --path option to use wallpapers from custom locations

• Blank screen: Ensure your compositor supports Wayland layer shell protocol
• High CPU usage: Consider lowering the FPS in the manifest or using static wallpapers
• Artifacts/glitches: Check GPU driver compatibility or try simpler effects

The daemon logs can help diagnose issues:

# Run with verbose logging
RUST_LOG=debug wlrs-daemon
