Welcome to the Oneiric Ocelot edition of Edubuntu, an open source and free Ubuntu derived operating system oriented towards educational institutions like universities and schools. It comes with a wide range of productive educational programs and uses the Unity interface as its main desktop environment.
Availability, supported platforms and boot options
Just like previous editions, the Oneiric Ocelot release of Edubuntu is distributed as Live DVD ISO images of approximately 3GB in size, which means that they can only be burned onto single layer DVD discs or written on USB sticks of 4GB or higher capacity.
From the boot prompt, the user can start the live session without any modification to the computer, boot an existing operating system that is installed on the first disk drive, run a memory diagnostic test, as well as to install the OS without testing it (not recommended).
Modern and eye-candy graphical session with powerful educational apps
This is the first release of the Edubuntu Linux operating system to use the modern and eye-candy Unity user interface as its default desktop environment, replacing the traditional GNOME 2 window manager that offered a two-panel layout.
Default applications include the Transmission torrent downloader, Liferea news reader, Mozilla Thunderbird email and RSS client, Mozilla Firefox web browser, Shotwell photo manager, Empathy instant messenger, Banshee media player, and Deja Dup backup software.
Summing up, Edubuntu 11.10 was officially announced back in October 13, 2011 and was supported by Canonical with software updates and security patches until May 9, 2013, during which it provided users with the first Unity powered educational system.
