How to switch to GNOME Desktop Environment in Ubuntu 14.04 Trusty Tahr
I am not a big fan of Unity Desktop Environment. I still like GNOME. As with GNOME I feel more comfortable.
Every time with new installation I install GNOME classic Desktop Environment. GNOME Classic a.k.a GNOME Fallback is one i use instead of unity, and also which is arguably the most familiar to that of the Ubuntu desktop that shipped in Ubuntu 10.04 by default.
To install Gnome Classic open a terminal and run following commands
sudo apt-get install gnome-panel
Now restart your Desktop.
