Binary package hint: gnome-panel
On the new version of Ubuntu : Feisty Fawn, the workspace switcher doesn't work with 3D Desktop. The first time I launched the 3D Desktop, all worked perfect : 4 workspaces. But the second time, there was only 1 workspace. And using workspace switcher options didn't change nothing. Whereas, I have now 4 workspaces BUT there is no more cube...
If I remember right, there was the same problem with Beryl but we had access to more options that could erase this problem.
