Okay , just a follow-up to th earlier post.  It looks like everything is 
working properly to setup the X-windows system.

Using the DISPLAY command noted by Ryan I can start the xclock 
application on any of the screens on the local machine as well as sent 
back the display to the remote client.  However,  my developed opengl 
applications seem to prefer running on :0.0 irregardless of any other 
display/screen arguments tried with the DISPLAY=localhost:[display],[screen]

sounds like a software/programming issue?  Using opengl with glut.  
Trying to find the function to accept/query for the specified display 
context and bind the output.  Looking for code source examples or 
tutorials on how to do that  -- assuming that appears to explain why 
common x-apps work and the locally created examples don't.
