Package xorg-xdmx: Information

Xdmx  is  a proxy X server that uses one or more other X servers as its
display devices.  It provides multi-head X functionality  for  displays
that  might  be  located  on  different  machines.  Xdmx functions as a
front-end X server that acts as a proxy to a set of back-end X servers.
All  of  the  visible  rendering  is  passed to the back-end X servers.
Clients connect to the Xdmx front-end, and  everything  appears  as  it
would  in  a  regular multi-head configuration.  If Xinerama is enabled
(e.g., with +xinerama on the command line), the clients  see  a  single
large screen.

Xdmx communicates to the back-end X servers using the standard X11 pro-
tocol, and standard and/or commonly available X server extensions.
