Ubuntu sponsor Mark Shuttleworth in his blog said that Ubuntu wants a new graphics system to switch the medium term. Wayland, a slim, OpenGL-based graphics and window system is in about a year, the X server and X Window System to replace. The User Experience to the conversion to Unity to bring desktop as could be, with X11 only with great difficulty and incomplete implementation

Wayland implements a protocol that clients addressing hardware applications with a compositor in turn communicate via the kernel. The task of the compositors client is events such as keys, mouse or touch screen events to the respectively addressed to pass. The clients update their own window and inform the compositor simply informed that a portion of the window has changed. The compositor then brings the change on the screen - taking into account possible window transformations such as scaling or rotations

It Wayland omitted numerous legacy of the 25-year-old X Window System - from the no longer used X-primitives for drawing lines and patterns of features for font handling and management of color tables to network transparency. Current toolkits for the X Window System can be ported to Wayland - a Qt port is underway. X11 applications can use to continue to Wayland, where the X server works as a client, Wayland, Wayland the input devices are used and X11 root window or single window over Wayland issues. This will require relatively few changes.
