I'm trying to design a digital signage system and I've hit a stumbling block. I've installed Xorg to run the graphical signage app. By default the server shows the X server on the main display (as intended), however I was wondering if it is possible to log in via SSH and then run a command (start-xibo.sh for arguments sake) and have this run the program on the X display?
Please update the question for clarity, from reading this it sounds like you are trying to run a graphical app and have it appear on the X server running locally on the box you ssh'ed into. If that is the case you need to set the DISPLAY variable, you can get more information about that here:

If you are using OpenSSH client, connect like this:
Then run you X program. It should appear at your local machine.
P.S. There can be some trouble with Xauthority. I can't remember at the moment but if you get it - leave a comment.
