XOrg

Summary #

X and X11 are basically interchangeable references to the client/server windowing system developed by MIT in the 80’s. Xorg is the current implementation of this used on most linux distros today (though Ubuntu is working on migrating to a different system called Wayland).

X provides the basic framework for a GUI environment: drawing and moving windows on the display device and interacting with a mouse and keyboard.
