xnest 2:1.11.4-0ubuntu10.3 (armel binary) in ubuntu precise

 Xnest is a nested X server that simply relays all its requests to another
 X server, where it runs as a client. This means that it appears as another
 window in your current X session. Xnest relies upon its parent X server
 for font services.
 .
 Use of the Xephyr X server instead of Xnest is recommended.
