      INSTALLING GNOME SHELL IN UBUNTU

Ubuntu has introduced unity as the desktop manager. But there are variety of options for desktop managers in Ubuntu. One of them is the gnome-shell. 



Gnome-shell:



GNOME Shell is the "official" shell developed for GNOME 3 by GNOME.
 GNOME  Shell  provides  core  user  interface functions for the GNOME 3
 desktop, like switching to windows and  launching  applications.  GNOME
 Shell  takes  advantage of the capabilities of modern graphics hardware
 and introduces innovative user interface concepts to provide a visually
 attractive and easy to use experience.

Installing gnome-shell:

In 11.10 onwards, GNOME Shell is  installable from the official repositories.You can find it in the Ubuntu Software Center, or
to install from a terminal type
 sudo apt-get install gnome-shell


Now you can try it by pressing ALT+F2  and entering gnome-shell --replace

Xfce is a lightweight desktop environment for UNIX-like operating systems. It aims to be fast and low on system resources, while still being visually appealing and user friendly.
Ubuntu has a xfce spin called xubuntu. You can install it from software center or command-line.

LXDE is an extremely light desktop environment that focuses on high performance and low resource usage. It is currently the default desktop environment used by Lubuntu


If you have regular Ubuntu installed, you can install it from the Software Center, just look for lubuntu-desktop in it or install it from command-line:
sudo apt-get install lubuntu-desktop


 Installing KDE in ubuntu

 KDE is probably the second most well-known DE available after GNOME.

 

If you have regular Ubuntu installed, you can also install it from the Software Center, just look for kubuntu-desktop in it.
Kubuntu doesn't have the best reputation among KDE users, being regarded as slow and using more memory than needed (there are posts of people using KDE on Arch Linux taking less than 450MB).

 Installing Cinnamon in ubuntu

 Cinnamon is a Gnome-Shell desktop fork. It is not strictly a Gnome-2 interface, although the developers aims are laudable - to produce a simpler more traditional desktop interface.

From a terminal type the following:
sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-stable
sudo apt-get update
sudo apt-get install cinnamon
