Kubuntu (// koo-BOON-too) is an official flavour of the Ubuntu operating system which uses the KDE Plasma Desktop instead of the Unity graphical environment. As part of the Ubuntu project, Kubuntu uses the same underlying systems. Every package in Kubuntu shares the same repositories as Ubuntu, and it is released regularly on the same schedule as Ubuntu.
Kubuntu was sponsored by Canonical Ltd. until 2012, and then directly by Blue Systems. Now employees of Blue Systems contribute upstream, to KDE and Debian, and Kubuntu development is led by community contributors. During the changeover, Kubuntu retained the use of Ubuntu project servers and existing developers.
"Kubuntu" is a registered trademark held by Canonical. It is derived from the name Ubuntu, prefixing a K to represent the KDE platform Kubuntu is built upon (following a widespread naming convention of prefixing K to the name of any software released for use on KDE platforms), as well as the KDE community.
Since ubuntu is a Bantu term translating roughly to "humanity", and since Bantu grammar involves prefixes to form noun classes, it turns out that the prefix ku- having the meaning "toward" in Bemba, kubuntu is also a meaningful Bemba word or phrase translating to "toward humanity". Reportedly, the same word by coincidence also takes the meaning of "free" (without payment) in Kirundi.
Comparison with Ubuntu
Kubuntu typically only differs from Ubuntu in graphical applications and tools:
|Kernel and core||Linux kernel and Ubuntu core|
|Primary toolkit||GTK+, Nux, and Qt||Qt|
|Email and PIM||Thunderbird||Kontact|
Kubuntu's Plasma Desktop is fully customizable without extra tools or configuration file editing. Originally designed to ease transition for users from other operating systems (such as Microsoft Windows) by allowing a similar desktop layout, the KDE Plasma Desktop incorporates widget-centric modularity that allows the user to incorporate function similar to all other operating systems and also create new functionality not found in other operating system desktops. Desktop effects are integrated in the standard KWin installation, and enabled by default.
Because Ubuntu and Kubuntu use the same sources, any application intended for one is installable and runnable on the other. Consequently, it is very common to see situations such as Firefox running on Kubuntu, or K3b running on Ubuntu.
The birth date of Kubuntu was the 10th December 2004 at the Ubuntu Mataro Conference in Mataró, Spain. Canonical employee Andreas Mueller, from Gnoppix, had the idea to make a Ubuntu KDE deviate and got the allowance from Mark Shuttleworth to start the first Ubuntu deviate, called Kubuntu. On the same evening Chris Halls from the Openoffice project and Jonathan Riddell from KDE started volunteering to the newborn Project.
I believe that the KDE community does phenomenal work, and having a community-driven distribution to showcase that work will help attract users and developers to the project. Our overall goal in the Ubuntu project is to further the adoption of free software on the desktop and the server, and we recognise that KDE is an essential part of the mix of desktop environments that allows people to find the best environment for their needs.
The Kubuntu team released the first edition, Hoary Hedgehog, on April 8, 2005.
On February 6, 2012 On April 10, 2012 , Blue Systems was announced on the Kubuntu website as new sponsor. As a result, both developers employed by Canonical to work on Kubuntu – Jonathan Riddell and Aurélien Gâteau – transferred to Blue Systems., Canonical employee Jonathan Riddell announced the end of Canonical's Kubuntu sponsorship.

Kubuntu follows the same naming/versioning system as Ubuntu, with each release having a code name and a version number (based on the year and month of release). Canonical provides support and security updates for Kubuntu components that are shared with Ubuntu for 18 months – five years in case of long-term support (LTS) versions – after release. Both a desktop version and an alternative (installation) version (for both x86 and AMD64 platforms) are available. Kubuntu CDs were also available through the ShipIt service (discontinued as of April 2011).

The desktop version of Kubuntu currently supports the Intel x86 and the AMD64 architectures. Some releases support other architectures including: SPARC, PowerPC, IA-64 (Itanium), and PlayStation 3 (however, a firmware update from Sony in April 2010 disabled OtherOS, making the PS3 unable to run other operating systems).
The minimum system requirements for a desktop installation are a 700 MHz x86 processor, 512 MB of RAM, 5 GB of hard drive space, and a video card which supports VGA at 640×480 resolution. The recommended system requirements for the desktop installation are a 1 GHz or better x86 processor, 1 GB of RAM, 15 GB of hard drive space, and a video card which supports VGA at 1024×768 resolution, and optionally supporting visual effects.
|Desktop & Laptop|
|Processor||1 GHz (x86)||Better than 1 GHz (x86)|
|Memory||512 MB||1 GB|
|Hard drive capacity||4 GB||10 GB|
|Video card||VGA @ 640×480||VGA @ 1024×768|
A Kubuntu distribution, by La Laguna University, is used in more than 3,000 computers spread in several computer labs, laboratories and libraries, among other internal projects in the Canary Islands.
