Wayland
- Intended to be a simpler replacement for X
- Wayland is a protocol for a compositor to talk to its clients as well as a C library implementation of that protocol.
- Weston: a minimal and fast reference implementation of a Wayland compositor, and is suitable for many embedded and mobile use cases.
- Not fully deployed yet. However, the ports of Gtk and Qt to Wayland are complete.
