Remove Ubuntu Unity
Posted on Monday November 19, 2012 by Eric Potvin
Canonical introduced, since Ubuntu 11.04, their new desktop environment software called Unity. Although, this great tool is very friendly some users still used to the classic Gnome environment. Unfortunately, since Ubuntu 11.04, Unity comes installed by default and if you are not use to it you have to uninstall and install the one yo like.
If you are not totally happy with Unity, here's a quick way to revert back to Gnome.
First of all, make sure you have the latest updates:
sudo apt-get update sudo apt-get upgrade
Now, let's install the classic gnome:
sudo apt-get install gnome-session-fallback
Once this is installed, Log out and choose the Gnome Classic by selecting it under the gear options.
sudo apt-get purge unity-lens-music unity-lens-applications unity-greeter unity-common unity-asset-pool unity-2d-launcher unity-2d libunity-misc4 libunity-2d-private0 gir1.2-unity-4.0 appmenu-gtk appmenu-gtk3 appmenu-qt indicator-appmenu
By removing unity, the
gnome-shell will be installed. This gives you an option to login with the gnome-classic automatically.
At this point you can disable overlay scrollbars in Ubuntu. Also, you can install the gconf-editor:
sudo apt-get install gconf-editor
This can be use to easily customize your new Gnome 3 environment.
