I used to regularly do ssh -X user@machine or ssh -Y user@machine so I
could run a graphical program on the remote machine and have the display on
the machine I was sitting at.  In fact, I used to do this at installfests
from my laptop (lapdog2) to the headless PXE server (fogtest) right next to
me.  That stopped working months ago and I have not been able to figure out
why or how to fix it.  Here is a sample of what I get:

larry@hammerhead:~$ ssh -Y fogtest
> Linux fogtest 2.6.32-41-generic-pae #91-Ubuntu SMP Wed Jun 13 12:00:09 UTC

As you can see, the ssh connection is fine but using a graphical program
like gedit does not. So I was making another attempt today (different
target) and it worked:

larry@hammerhead:~$ ssh -Y sunfish

Anyone know where to look or how to fix fogtest?
