I have been using gnome fallback for more than a year, but recently I have come across this image:
However, when in virtual machine (new copy of ubuntu 12.04) I change to gnome 3 shell, the desktop is not even similar to the one in the photo above. I am wondering if there are others things that I am missing/have to do....to get to the same thing (or similar) that you can see in the image above.
NOTE: Here is a screenshot from the virtual machine after I used these commands:
sudo add-apt-repository ppa:gnome3-team/gnome3 sudo apt-get update sudo apt-get install gnome-shell
