Every April, Canonical releases a new version of the consumer-oriented and very popular Linux distro Ubuntu. The latest version is called Ubuntu 11.04 Natty Narwhal, and the biggest change in ths version is a completely new user interface called Unity. Unity is an interface that that was previously reserved for netbooks.

The deveopers of Ubuntu has clearly taken some design ideas from Apple and placed application taskbar on top. If you do not like these changes or other changes that come with Unity, you can choose to use Ubuntu Classic, a GNOME 2 interface.

You can also install the resently released GNOME 3, by following these simple steps:

Open Terminal ( Default shortcut is : CTRL+ALT+T ) and Type the following commands (Make sure that you haven’t opened Ubuntu Software Center or Synaptic Package Manager while installing package from the command line).

sudo add-apt-repository ppa:gnome3-team/gnome3
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install gnome-shell

In addition to lots of bug fixes and a more intuitive user interface, Firefox 4  is now the standard Web browser, and Rhythmbox is removed in favor of the Banshee Media Player.
