Two X servers, one box

[Cook, Rich]

Hi, 
I am trying to run two instances of X.Org X Server 1.10.4 per node of our dual-GPU Red Hat cluster. 
I do this: 
/usr/bin/startx /usr/bin/xterm -display :0 -- -nolock -auth /g/g0/rcook/.Xauthority-0 :0
and this: 
/usr/bin/startx /usr/bin/xterm -display :1 -- -nolock -auth /g/g0/rcook/.Xauthority-1 :1

And I almost get there -- in fact, it worked once.  But mostly the X server starts but I get "invalid MIT-MAGICK-COOKIE" errors which don't show up in the Xorg logfile, so I assume I'm very close, just doing something wrong with xauth. 

Can anyone on this list help a poor man out?  Thanks
