Wayland-friendly Linux desktop environment prototype written in Odin, inspired by MMO game UI and game screen layouts.

What this is

  • A base desktop shell layout for Wayland using SDL2.
  • A simple UI renderer with a dock, status bar, and desktop widgets.
  • A foundation to expand into a full game-themed Linux desktop environment.

Files

  • main.odin - entrypoint with desktop UI rendering and event loop.
  • README.md - project overview.
  • .gitignore - ignores build artifacts.

Requirements

  • Odin compiler installed on Linux.
  • SDL2 development libraries available.
  • Optional: Wayland session or SDL2 configured to use Wayland.

Build and run

odin run main.odin

If you are in a Wayland session, SDL2 should automatically use Wayland when WAYLAND_DISPLAY is set.

To force SDL2 to use Wayland:

SDL_VIDEODRIVER=wayland WAYLAND_DISPLAY=wayland-0 odin run main.odin

If you are running under X11, use:

DISPLAY=:0 odin run main.odin

This app now auto-detects the desktop resolution and prints the active SDL video driver at startup. It also attempts to load DejaVuSans.ttf from the system font directory for real text rendering.

The desktop now renders floating window panels on top of the main background, so windows can appear as desktop UI elements.

A Settings Manager GUI is available via the Settings button or by pressing S.

Settings let users change the desktop theme, select wallpaper/game-world/MMO background modes, toggle the clock, and lock or unlock panel movement.

Press R to randomize the world seed when the seed is unlocked. Press I to import models from GAMEUI_MODEL_PATH or GAMEUI_MODEL_PATHS. Press Alt+Tab to cycle the active window and bring it to the front.

Press F to toggle the current window to fullscreen, which also forces a simplified wallpaper-style desktop background to reduce GPU load while a fullscreen app is active.

Notes

  • This is a prototype UI; text is currently rendered with placeholder rectangles.
  • Add SDL_ttf support later to render real text labels and game UI fonts.
  • Model import is supported via environment variables and accepts .obj, .fbx, .gltf, .glb, .dae, .stl, .ply, .3ds, and .blend placeholders.

Next steps

  • Add interactive desktop windows, clickable icons, and animated transitions.
  • Integrate SDL_ttf for real text rendering.
  • Expand the shell with workspaces, notifications, and app launching.
