I have a second X11 display port which is created by VNCServer on startup (vncserver :1 -geometry 1280x800); and I would like to start a GUI-only application on this second display at startup also.

How can I do this?

(the application in question is PS3MediaServer FYI)

Most X applications take a -display or --display argument. Setting the DISPLAY environment variable supported by almost all X applications, since support for it is built into libX11's XOpenDisplay() API.

Thanks. PS3MediaServer appears to be a .jar executed by the JVM; how do I tell the JVM which X display to use? Like so? java blah.jar $DISPLAY=":1" ? – user33110 Aug 30 '10 at 5:12

Put this in a script and run it at startup:

#!/bin/sh
DISPLAY=:1.0 ; export DISPLAY
java ...
