Unity 3D is incredibly unstable for me. Still, I love the interface and would like to continue using it. Is there any way to force Unity 2D?

Btw: I've already filed a bug report against xserver-xorg-video-ati

Just install unity-2d Install unity-2d and reboot. At GDM login screen, in the drop-down box at the bottom of the screen select 'Ubuntu Unity 2D session'. In consequent bootups, the Unity 2D session will become the default.

In case you want to enable/disable composting in Unity 2D, you can install the Unity 2D tweaking tool by following this guide.
