Unity is geared towards a ‘light' variation of Ubuntu, which concentrates on getting the user to the web as quickly as possible. We would like Unity to be the default session for Ubuntu Netbook Edition 10.10 (Maverick) and we hope to present some ideas this week to show how we think we can make the transition to a mostly web-based session to a more fully-featured session for netbooks (including search, better file management, and easier window management).
Install Unity in Ubuntu
Open the terminal and run the following commands
sudo add-apt-repository ppa:canonical-dx-team/une
sudo apt-get update
sudo apt-get install unity
Logout and then log back in selecting ‘Unity UNE Session' from your login screen.
