By default it now doesn't allow insecure X connections. The best 
solution is to use 'ssh -X' rather than 'rsh' because it will then work 
- and of course its a whole lot more secure. If you cannot ssh for 
whatever reason then you'll have to modify /etc/X11/gdm/gdm.conf but it 
does reduce security on your machine quite significantly.
