Comment 49 for bug 1251281

@plotkin it should work as long as you tell NX 3 to run the command:
gnome-session --session=gnome-flashback --disable-acceleration-check
(Not tested)

You may have to put that line in a script, and tell NX 3 to launch that script. That's what you will have to do with X2Go at least.

I wrote the logic in X2Go for "--session=gnome-flashback". I still need to write the logic in X2Go for "--disable-acceleration-check". Once I do, X2Go users can simply select "GNOME" as their session.
