RE: Running X on a virtual dedicated server

Ok, I am trying to manually set the display using setenv DISPLAY and I
get a command not found error. Any suggestions?

Try this command:

echo $DISPLAY

This will tell you what display the X programs are connecting to. This
should be an SSH tunnel, something like:

:10.0

A good program to test if everything is working is "xlogo", very simple
but connects over the X11 protocol.

Also, I'd stress that "xhost +" is ONLY for debugging. SSH should set
up the permissions so that this isn't necessary, it's a significant
security issue to leave that open regularly.
