The X.Org Foundation (or X.Org for short) is a foundation chartered to develop and execute effective strategies that provide worldwide stewardship and encouragement of the X Window System and related projects (Mesa, DRI, Wayland, etc.). The X.Org Foundation has an open membership, and a Board of Directors which is elected from the membership. X.Org develops the X Window System, the standard window system for open source operating systems and devices. Today, as the result of more than 20 years of work by teams of leading open source developers, most of the graphical user interfaces for Unix and Linux systems rely on X.Org. The X.Org Foundation Board of Directors is responsible for non-technical support and guidance of the X.Org project. X.Org is responsible for the design of the X libraries which interface with application, the acceleration architectures used for graphics, and the graphics and input drivers. In particular, it has been at the center of the recent restructuring of the Linux graphics driver stack.
