Wayland is protocol for providing graphical output to Linux/Unix users. It is intended to be a lightweight alternative to the X11 subsystem.

Wayland is a protocol for a compositor to talk to its clients as well as a C library implementation of that protocol. The compositor can be a standalone display server running on Linux kernel modesetting and evdev input devices, an X application, or a wayland client itself. The clients can be traditional applications, X servers (rootless or fullscreen) or other display servers.

Source: wayland.freedesktop.org
