Welcome to the Natty Narwhal edition of Kubuntu, an open source Ubuntu flavor that uses the KDE Software Compilation project to replace the Unity desktop environment of Ubuntu with a more familiar and productive one suitable for home users and small offices.
Still distributed as Desktop and Alternate CDs
Kubuntu 11.04 was officially announced on April 28, 2011 and supported with security and software updates until October 28, 2012. It can be downloaded from Softpedia as Desktop (Live) CDs and Alternate (Install) CDs for the 64-bit and 32-bit hardware platforms.
The functionality and look of the Desktop CD's boot menu is similar with the one found on the previous release of the distribution, allowing the user to start the live environment and then choose if he or she want to try or install the operating system. It addition, it is possible to run a memory test, boot an existing OS from the first drive, and check the disc for defects (only if using a CD media).
Still using a modern and productive KDE desktop environment
Except for the new artwork, this release still uses the same modern and productive KDE desktop environment that was available in the last four releases, which uses a bottom taskbar and a Desktop Folder widget.
Rekonq is now the default web browser, but the user is still able to install the Mozilla Firefox web browser using the script provided on the Internet section of the main menu, and the OpenOffice.org office suite was replaced with the modern LibreOffice software.
Among other interesting apps, we can mention the KMail email client, KTorrent torrent downloader, Amarok music player, K3b CD/DVD burning software, Dragon Player video player, Kate advanced text editor, and various other KDE-specific utilities.
In conclusion, Kubuntu 11.04 (Natty Narwhal) proved once again that this KDE-based Ubuntu flavor can be a very stable and reliable operating system for home or small office computers. It is no longer supported and has been archived for historical purposes only.
