Jonh,

The DISPLAY variable isn't set by default :
ssh redhat_host
user at redhat_host's password:
Last login: Thu Jul  5 15:43:26 2007 from sun-server
[user at redhat ~]# echo $DISPLAY

[user at redhat ~]#

When I did "ssh -X", I 've got "localhost:10.0" in the DISPLAY variable. It's 
seems the proub that ssh do something but not enought.
