xdmx - 2:1.20.4-1+deb10u4 main

Xdmx is a proxy X server that uses one or more other X servers as its
display device(s). 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.
