Running Gnome 2 In Debian Wheezy but would like ability to run Gnome 3

http://www.linuxquestions.org – I was running Gnome 3 with a blinking screen until I installed the NVIDIA GeForce 9800 GT drivers. The screen no longer blinks but I now can only run Gnome 2, albeit, Gnome 2 looks nice. Since the Gnome 3 desktop is software I chose this forum. (HowTos)
