Install GNOME on Ubuntu 14.04

Unity slows down PC and it's very difficult to adjust to new environment. That's why I install GNOME desktop:

sudo apt-get install gnome-session-fallback

Restart PC and on login screen choose GNOME metacity session You should see desktop like this:

Move close, minimize, maximize buttons to the right

gsettings set org.gnome.desktop.wm.preferences button-layout 
':minimize,maximize,close'

Good old and familiar interface is back.
