GNOME 3 on Ubuntu

What is GNOME ? 

GNOME is a desktop environment and graphical user interface that runs on top of a computer operating system. It is composed entirely of free and open source software. It is an international project that includes creating software development frameworks, selecting application software for the desktop, and working on the programs that manage application launching, file handling, and window and task management.

Simply Beautiful 

GNOME's new desktop takes elegance to a new level. We've swept away the clutter and made a simple and easy-to-use desktop, and we've made this the most beautiful GNOME desktop ever, with a new visual theme, a refined new font and carefully crafted animations.

An overview at a glance

The Activities Overview is the portal to all your computing activities. Quickly accessible using the top-left hot corner or windows key, it provides a single place to access windows, applications and even messages. The dash allows you to see which applications are currently running and the workspace switcher can be used to group windows.

 

Integrated messaging

GNOME 3 incorporates a unique, built-in messaging system. Messages can be directly responded to from notification popups, and you can access your previous communications from the Messaging Tray which is always available from the bottom of the screen. This means that holding a conversation does not require repeated window switching
