This is likely an X  Authentication problem.

The X server is running on the thin client, but processes that run on 
the thin client are not authorized to access the display.  It is because
the X session has been authenticated via the display manager running 
back on the ltsp server.

The quick and dirty way to get around this is to set:

     DISABLE_ACCESS_CONTROL = Y

in the lts.conf file.

I'm looking for a better way to resolve this problem that doesn't open 
up the workstation display to the world.

It's one of those things that will probably only take an hour or so to 
figure out.  The big problem is finding that hour.
