Welcome to the Natty Narwhal edition of Edubuntu, an open source Linux distribution built around the GNOME 2 desktop environment, a pretty neat collection of educational applications and using the stable and reliable Ubuntu base.
Availability, supported platforms and boot options
This Edubuntu release is dubbed Natty Narwhal and it's available for download since April 28, 2011 as two Live DVD ISO images of approximately 3GB in size each. The user will have to burn the ISO images onto DVD discs or USB flash drives of 4GB or higher capacity in order to boot from them.
From the boot manager it is possible to choose a preferred language and keyboard map, start the live session with default options, run a system memory diagnostic test using Memtest86+, boot an existing operating system from the first disk, as well as to install Edubuntu without testing it (not recommended).
Still using the traditional GNOME environment, same great educational apps
Even if this is the first release of the Ubuntu operating system with the modern and astonishing Unity user interface, the Edubuntu 11.04 release still uses the traditional GNOME 2 desktop environment, which offers a two-panel layout, as well as a clean and productive graphical session.
While it comes with almost the same default applications that can be found in previous releases, among some of the newly introduces educational programs we can mention Celestia, GeoGebra, Lybniz Graph Plotter, LRF Viewer, Pencil, ScribusNG, LibreCAD, FreeMind, Calibre, Stellarium, and the entire LibreOffice office suite.
Summing up, Edubuntu 11.04 (Natty Narwhal) is yet another stable and reliable Linux operating system suitable for educational use. This release was supported by Canonical with security patches, bugfixes and software updates until October 28, 2012.
