Yes, but was X11 *running*?  If it wasn't launched (I'm assuming that, 
if your X11 isn't the Panther X11, it's an app that gets launched, just 
as the Apple X11 that comes with Panther is an app that gets launched), 
you'd have to launch it.

You'll *also* have to set the environment variable DISPLAY to :0.0 so 
that X11 applications will attempt to connect to the local X server.  Do

	setenv DISPLAY :0.0

if you're using a C shell-compatible shell (command prompt ends with a 
"%") or

	DISPLAY=:0.0; export DISPLAY

if you're using a Bourne-compatible shell (command prompt ends with a "$").

You might want to put that in your .login (for C shell-compatible 
shells) or .profile (for Bourne-compatible shells) so that it happens 
automatically.
