Kubuntu — Ubuntu with the KDE Plasma desktop

Characteristics and components

At its core Kubuntu runs on the Linux kernel and is packaged and delivered as a distribution that shares Ubuntu's installers, package management and system configuration. The defining difference is the default desktop: Kubuntu ships the KDE Plasma desktop and a set of native KDE apps instead of the GNOME shell typically used by Ubuntu by default. Common KDE applications found in Kubuntu include file manager, terminal emulator, e-mail client and text editor from the KDE suite.

History and development

Kubuntu emerged as an alternative offering to users who preferred the KDE desktop paradigm. It is developed alongside other official Ubuntu flavors and follows Ubuntu's release schedule and repositories, which means security updates and version upgrades are coordinated with the broader Ubuntu project. Development is driven by volunteers and contributors from both the Ubuntu and KDE communities.

Uses and target audience

• Users who want a highly configurable, visually polished desktop interface.
• People who prefer KDE applications such as file management, office integration and multimedia tools.
• Systems where integration with KDE tooling or a particular look-and-feel is desired.

Because Kubuntu shares the same underlying system as Ubuntu, software available for Ubuntu generally works on Kubuntu; conversely, an Ubuntu installation can be converted into Kubuntu by installing the KDE desktop packages and related themes and apps, and a Kubuntu system can be changed to the Ubuntu desktop in the same way.

Notable distinctions

Compared with Ubuntu's use of GNOME, Kubuntu emphasizes KDE's approach to configuration, widgets, and window management. Many of the graphical tools and utilities come from the KDE applications family. In practice the choice between Kubuntu and other Ubuntu flavors is mostly about desktop environment preference rather than core technical differences.
