You're running the Gnome Fallback desktop (Gnome Panel). It's not the same desktop as Gnome Shell. This is usually because of missing drivers. You might want to look for proprietary drivers.

sudo add-apt-repository ppa:gnome3-team/gnome3
sudo apt-get update
and install the stable gnome-shell:
sudo apt-get dist-upgrade
