Comment 8 for bug 290747

Dustin-

Thank you for the reply. I'm using Hardy/Intrepid as the guest, not the host. So the scenario is you open a terminal on the Intrepid machine, run 'ssh -X user@host' on the Intrepid machine, where 'host' is another Unix server (in my case Solaris 10).

What I originally thought was a bug or deprecation of behavior is actually a setting that's buried in the Login Window security settings. By default, on a new installation, Hardy and Intrepid have the "Deny TCP connections to Xserver" setting checked. This prevents X11 programs on a foreign Unix host from appearing on your Ubuntu guest.

The only reason I didn't ask to have this closed is after extensive googling, it is not obvious that this is the setting required to allow X11 sessions to be passed in to the Ubuntu guest. Once you unhceck this option, everything works as expected. I'm just hoping that documentation is updated (even if it is just people finding this bug report) that makes this setting more visible.

I have also posted the steps on a related forum post here:
