The Gnome 3 desktop for Linux is planned to be released in early 2010. But you can experience it in Ubuntu Karmic Koala through Gnome 3 Shell. We will show, how you can try out all the features of Gnome 3 thorugh Gnome 3 Shell.

Here is a screenshot of Gnome 3 shell:

Step by step instructions:

1. Open a Terminal and run this command to install the Gnome Shell:

sudo apt-get install gnome-shell

2. After the installation is complete, you can start it by running the following command in the Terminal:

gnome-shell --replace

3. If your graphics is rendered by the Intel GPU and you are getting a blank screen after running the previous command, you can fix it by running this command in the Terminal:

export GNOME_SHELL_DISABLE_TFP=1

Note: Gnome Shell is still in the development stage and there is always a possibility that if may break some parts of your Ubuntu installation. We do not take any responsibility for that, and request you to try it on your own risk.
