My xstartup looked nearly the same.  I uncommented the exec... line 
earlier and just now uncommented the unset... line.  After rebooting 
(and restarting vncserver) and closing the firewall it came up just the 
way I expected it to.  Now, how can I configure the firewall to accept 
vnc connections without turning it off?  And how can I get vncserver to 
start on boot?

I thought I heard once that I don't need a VNC client to do this as X11 
will do it if it is configured correctly.  Is this a correct statement 
or am I required to use a client?

Thanks,
Jeremy
