Something close - here is video of an EOMA68-A20 working with 3D on
Ubuntu:

yep; the openGL stack works, in both X.org and Wayland.
looking at the various shots on the eoma_boot page, what desktop(s) / window managers have you successfully brought up with compositing?
looking through them it looks mostly like gnome2, though i see some mentions of (a composite-less?) gnome-fall-session and compiz as well?
The one OS image here has options that work to login under these different window managers (click on the round logo to the right of the password box) xubuntu, lubuntu, ubuntu gnome classic and openbox:

The normal Ubuntu unity desktop is also an option, but gives a blank desktop because composting is not working. I sorely wish to have compiz and desktop cube working, but util Allwinner release all the information for the graphics controllers libv and others have to do everything by guesswork.
(Also, the username/password jm/jm works - the other default username has problems and will return back to the login screen.)
There is option to upgrade from Ubuntu 13.04 to to Ubuntu 13.10. If taken, the ubuntu gnome classic will be replaced with something that sounds similar (I forget the exact name), but it is not the same as gnome classic. It also gives blank desktop (though the other window managers remain usable).
