My main workstation is OSX (as I spend a lot of time developing iOS and OSX software), however I use Ubuntu for a bunch of things.
I've got Ubuntu running on another machine, and would like to tunnel the desktop over ssh to OSX. I'm an 1000mbit ethernet.
It works for the following:
ssh -X firstname.lastname@example.org nautilus& #Or firefox, etc - will open the window on my OSX Machine
However for a whole desktop:
It gives the error message "We failed but the fail whale is dead". . . this has to be the most fantastic error message ever (although it doesn't help me very much in explaining what went wrong).
