Ubuntu 11.10, which is due for release next month, will include the Gnome 3 desktop environment. But if you don’t want to wait, you can type a few commands into the terminal to install Gnome 3 in Ubuntu 11.04.
But be warned. This will make the Unity desktop environment unusable, so only follow these steps if you’re sure you want to use Gnome 3 (which is a great desktop environment).
First, add the Gnome 3 repository by typing the following command. If required, also type your sudo password when asked for it.
sudo add-apt-repository ppa:gnome3-team/gnome3
Next you’ll want to update everything with these two commands. These might take a few minutes to finish.
sudo apt-get update
sudo apt-get dist-upgrade
Now you’re ready to install Gnome 3 with this command:
sudo apt-get install gnome-shell
This might take a few minutes as well. When asked for a Y/N answer, type Y. Once it’s finished, restart your computer. When you reach the login screen, choose the Gnome desktop environment and enjoy.
