XDMCP handles all the video on its own.
What you need to do is configure your local machine's GDM (or whatever display manager you're using) to enable the "XDMCP Chooser". Then your login screen will give you an option to run the XDMCP Chooser. Pick that option and you'll get a list of all machines on your network that have XDMCP enabled. -Rob ------------------------------------------------------------------------------ Register Now for Creativity and Technology (CaT), June 3rd, NYC.
