Using NX with Unity in 11.10

I'm trying to use nx to login remotely to my desktop. But when I do, because of unity I get the following screen:

It looks like all I can do is access the file browser from here. I tried following the instructions in this post, but they don't work (presumably because I don't have the necessary gnome stuff). How do I launch the unity-2d "session" on 11.10?

You use gnome-session --session=ubuntu-2d as the command in your NX client.

The problem is described on this nomachine webpage.

I had to check which sessions are available for gnome-session in /usr/share/gnome-session/sessions and modify the session startup (--session=gnome-classic changed to --session=gnome).
