Hi,
	Try setting your environment variable prior to running:

[t]csh: setenv DISPLAY :0
[ba]sh: export DISPLAY=:0

Might sound obvious, but make sure X11 is running already.

Sometimes the value "localhost:0" works instead of just ":0", though
localhost is assumed otherwise.

You can add this line to your startup script ~/.cshrc or ~/.bashrc for
convenience.
