          Platform: Other

Often, one would like to run apps in a nested
X server.  A good one is Xephyr.  To try this on ubuntu, 
first install with
   sudo apt-get install xserver-xephyr
then start a nested X server with
   Xephyr :1 -ac
then verify it's working with
   DISPLAY=:1 xeyes
If that works, then start a Wine app, e.g. notepad:
   DISPLAY=:1 wine notepad
