problem with x-window
 

I have a system with linux suse 9.3
I connect to another system far away (with the command ssh)
I want to run a scientific program installed in that pc.
The program starts running normally but it should also open a window in my pc.
In that point i get an error message about my x-window display.
How can i see which x-window program my system uses and configure it??

thanx

Do you have X-forwarding enabled?
Try connecting with ssh -X user@host.somewhere.com
See also man ssh
