Use the above if your sure you enabled x-forwarding in your ~/.ssh/config 
or in /etc/ssh/ssh_config. If not, a better idea would be to use

    ssh -v -X -l <user> <system> <x app>

instead. And an other one: some x-apps behave curious if started this way. 
They depend on being started in an interactive shell. In such case you 
might even be better of using:

    ssh -v -X -l <user> <system> /bin/bash -l -i -c "<x app> &"

to make sure your x-app is seeing an interactive shell environment!

BTW: did you set "export DISPLAY=:0.0" ("setenv DISPLAY :0.0" for csh) 
before calling ssh? SSH wont forward X if no display variable was set 
before. It's regardless of an X-server beeing started. Just make shure 
"DISPLAY" exists and is exported.
