 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
2012 i686 GNU/Linux
Ubuntu 10.04.4 LTS

echo $DISPLAY

Do you get something like localhost:10.0?

Yes, both on the machine that works (sunfish) and the one that does not
(fogtest).

OK, we might have to debug the gconf stuff :).

Before that, try starting a non-GNOME app such as xterm or xeyes.

larry@fogtest:~$ gedit
GConf Error: Failed to contact configuration server; some possible causes
are that you need to enable TCP/IP networking for ORBit, or you have
stale

NFS locks due to a system crash. See http://projects.gnome.org/**gconf/<http://projects.gnome.org/gconf/>for

information. (Details -  1: Failed to get connection to session: Failed
to
connect to socket /tmp/dbus-sjFuIo1Vhr: Connection refused)

ls -ld /tmp/dbus-*

Wonder if it's trying to use the wrong socket. There might be a stale
socket since you're running headless, but boot should fix that by cleaning
out /tmp. Does fogtest get shutdown or do you hibernate it?

The obvious solution is you need to start using vim :).

^C
larry@fogtest:~$

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?
