Ok, that's a good start.

DISPLAY is an environment variable used by X Windows to determine what
physical (or virtual) display to use. This is how you can run any X
application (like insight, xterm, xmtr, etc) on one machine and have it
display on a monitor attached to a different workstation.

>From your shell, type "echo $DISPLAY". You should see something like
"localhost:0" or something. If not, set DISPLAY according to the
instructions on the X man page ("man X"; look for section "DISPLAY
NAMES").

Of course, the other simple test of whether or not DISPLAY is set is to
run some other X application. Do other X applications work?
