Installing the gnome desktop in Ubuntu 12.04

Yeah, I also didn't like the Unity which comes by default in Ubuntu 12.04. Just install the gnome-session-fallback and you are good to go

sudo apt-get install gnome-session-fallback

#In the newer version you may want to try

sudo apt-get install gnome-session-flashback

agentBUSH@ChrUbuntu:~# sudo apt-get install gnome-session-fallback
Reading package lists... Done
... bla bla bla ...
Processing triggers for libc-bin ...
ldconfig deferred processing now taking place

After installation, log out and at the log-in screen you will have the gnome-classic.
