Xdmx

Xdmx or DMX (both abbreviations are indifferently used) is the Distributed Multihead X Project. It acts as a proxy X server for multiple back-end X servers. When combined with Xinerama support, the multiple displays handled by DMX are presented to the user as a single unified screen.

For example, DMX could provide multi monitor support using two desktop computers, each of which has a single monitor. Or, it could unify a 4 by 4 grid of monitors between 8 computers each with 2 monitors attached to them.

DMX was developed and runs under Linux. In addition, DMX has been reported to work under most X11 architectures such as X11 running under Mac OS.

A common misconception about DMX is that it is a window manager. DMX is not a window manager, but another X server. As a result a window manager, such as KWin, Metacity, Fluxbox, etc., is needed to run on top of DMX for maximum usage. The DMX server is known as the front-end X server, while the servers that the DMX server connects to are known as the back-end servers. X clients can use the DMX server just like a normal X server, while the DMX server uses the back-end servers to actually do the drawing.
