There is a way to run graphics programs on the 4D under release 3.1
without logging in at the console (for example, from another terminal):

    1)	Execute the command "/etc/gl/restartgl".  This will start
	the window manager at the console, running as your user ID
	(make sure you logout or kill the window manager when 
	you're done).  You will need to wait a few seconds for 
	it to load, as you would if you had logged in at the 
	console itself.
	
    2)	Run your graphics programs.
    
    3)	When done, you can get rid of the window manager doing a
	"ps -ef" command to find process "/etc/gl/grcond", and
	then killing that process (or you can logout at the console
	itself).

I've tried this on a 4D/60T, but it will probably work on any IRIS
running software release 3.1.  It's not the most convenient procedure 
in the world, but it will let you do what you want to do.
