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

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

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?

Please protect my address like I protect yours. When sending messages to multiple recipients, always use the BCC:
(Blind carbon copy) and not To: or CC:. Remove all addresses from the message body before sending a Forwarded message. This can prevent spy programs capturing addresses from the recipient list and message body
Well,
It could be a variety of things:
1. dbus issues: Resolve by deleting ~/.dbus*
2. Permissions: Press alt + F2 and type gksu gedit to verify or run via root
3. Issues with file corruption: sudo touch /forcefsck && sudo reboot
