The Ubuntu Gnome Shell Remix 12.04 is now available for download in both 32 & 64 bit versions here:

I've found this distribution is wonderful for all the pre-built tweaks already in it. It returns the traditional Gnome 2.x functionality with the latest linux kernel updates. This is my favorite distro bar none.
Highly recommended.
