Gnome 3 requires a hw support from the video card. Before the upgrade, have you successfully used some compositing window manager through x2go (compiz, metacity with compositing enabled)? I doubt so...
Up until now, I have not heard any news that Gnome 3 would provide a fallback, which would be visually similar to the "normal" Gnome 3. (Canonical has such a plan for its Unity - to be released in autumn 2011.)
This is by the way the reason, why I am in a search for a GNOME replacement...
No, I did not use a compositing window manager, just the default Gnome 2 settings which did work fine with x2go.
The "fallback" with Gnome 3 is not at all similar to "normal" Gnome. It is not really a desktop environment at all -- seems like just a window manager.
I have never tried KDE before, but I tried it after having this problem. I could not stand it, and it had some compatibility problems (it would not work properly with gnome-terminal -- the windows kept auto-shrinking themselves).
Then I tried LXDE, and that works great with x2go and all my usual programs. I also like the feel of it, and it seems fast (KDE felt slow to me). So it looks like I am switching to LXDE.
