Abstract
An X display may be dynamically rerouted to a different graphics terminal, or to several graphics terminals, without disrupting X clients. The corresponding X server architecture includes a static, protocol router part which acts as an endpoint for client connections and which routes X protocol to one or more X server displays, and a dynamic X display part which maintains the state and contents of the display. An X display may maintain its state and display contents entirely in memory without any need for physical display or input devices, in which case it is termed a “headless X display” and provides a virtual X server display that appears to the host as if it were a user-interactive display. The architecture allows for any number of X displays to be attached to the protocol router for multi-user, fault tolerant or suspend/resume functionality.
