Xorg

XOrg is commonly used to refer to the X.Org project and the X.Org Foundation, the nonprofit organization that coordinates the X Window System. The X Window System, commonly known as X11, provides a framework for graphical user interfaces on Unix-like operating systems by enabling a network-transparent display rendering model. The X.Org project coordinates the development of the X.Org Server, the reference implementation of the X server, along with core libraries, extensions, and drivers that support rendering and input handling. Software built on X.org forms the basis for many open-source desktop environments, window managers, and toolkits.

The X system operates on a client-server model: X clients request drawing to an X server that owns the display and input devices, communicating over the X protocol. This architecture supports networked displays and modular integration of components such as window managers, compositing managers, and hardware drivers. The X.Org Foundation and its contributors emphasize open development, collaboration across organizations, and community governance, with participation from graphics developers, distributors, and end users.

In contemporary Linux ecosystems, many distributions offer X.Org as a stable display server option alongside Wayland, a newer display protocol intended as a modern replacement. Wayland is designed for simpler, more efficient compositing, while X.Org remains available and actively maintained to ensure compatibility with existing software and workflows. The term XOrg is sometimes used informally to refer to the X.Org Foundation or Project, but the official naming is X.Org.
