To clarrify, there were 2 versions of Unity in Ubuntu 12.04 Precise. One version that renders everything via 
3D rendering on the GPU, via Compiz with a custom GUI toolkit, and a version of Unity designed to work on 
lighter hardware, that doesn't necessarily get rendered via 3D rendering, based on Qt version 4.

As of Ubuntu 12.10 and later, there is only one version of Unity, the 3D rendered version, based on the 
custom toolkit. However, Unity is undergoing another rewrite, based purely on Qt5.
