You may want to install and use Classic Gnome on your Ubuntu PC, unlike Ubuntu 11.04 the classic gnome desktop is no longer installed as an alternative to the new Unity desktop. I thought I’d quickly share how installed it on my Ubuntu 11.10 development machine, which now enables me to use either Unity or the Gnome Classic desktop enviroment.
So using the terminal, install the gnome-session-fallback package like so:-
sudo apt-get install gnome-session-fallback
So to now use your the newly installed Classic Gnome desktop enviroment simply logout and then use the gear icon just above the username box to change the desktop session to ‘Gnome Classic’.
