Nothing OS Wayland Desktop Environment (Rust Prototype)

A custom Wayland Desktop Environment (DE) and compositor prototype inspired by the minimalist dot-matrix aesthetic of Nothing OS. Built in Rust utilizing the Smithay compositor library, this project features a dual-mode user interface, robust window management, and interactive widgets.

🎨 Design Philosophy

Inspired by Nothing's signature brand design, this DE implements:

• NDot Style Typography: A custom dot-matrix glyph rendering engine built into the compositor.
• High-contrast Minimalist UI: Sleek black, white, and gray color palette.
• Glassmorphic & Rounded Elements: Smooth borders, curved docks, and soft shadows designed to feel premium.
• Dual Mode Interface:
  • Desktop Mode: A clean workspace with a top-docked status bar showing active layout, status icons, and time.
  • Dashboard Mode: An interactive, full-screen widget panel inspired by the Nothing OS widgets.

✨ Features

• Dual-Mode UI:
  • Desktop Mode: Renders a persistent status bar panel at the top of the screen.
  • Dashboard Mode (Toggled via Super + D): Renders a beautiful full-screen overlay with dot-matrix digital clock, CPU usage circular gauge, RAM usage circular gauge, system uptime, battery status widget, and interactive buttons.
• Interactive Widgets:
  • Wi-Fi Toggle Widget: Interactive widget that toggles the Wi-Fi state on and off, changing color and updating icons.
  • Theme Toggle Widget: Interactive widget that toggles between Dark Mode and Light Mode, dynamically updating the compositor background color and text themes.
• Window Management:
  • Tiling Layout (MasterStack): Active windows automatically tile, splitting the screen into a primary master area and a stack area for other windows.
  • Floating Layout: Free-form window positioning.
  • Layout Toggle (Super + T): Switch dynamically between Tiling and Floating layout modes.
  • Keyboard Window Cycling: Navigate through open windows using Super + J (next) and Super + K (previous).
  • Close Window: Instantly close the active window with Super + Q.
• Intuitive Mouse Grabs:
  • Titlebar Click-and-Drag: Grab and move any window by simply clicking and dragging its top 32 pixels—no modifier keys required!
  • Classic Super-Drag: Drag windows from anywhere on their surface by holding the Super key and left-clicking.

🚀 Getting Started

Prerequisites

You need the Rust toolchain installed, alongside development libraries for Wayland, EGL, GBM, and xkbcommon.

On Ubuntu/Debian:

sudo apt install build-essential pkg-config libxkbcommon-dev libwayland-dev libgbm-dev libegl-dev libxml2-dev libinput-dev libudev-dev

Running

To run nested inside an existing X11 or Wayland session:

cargo run

Note: Ensure you have weston-terminal installed if you want to spawn the default terminal using Super + Enter.
