New in Kubuntu 10.04

New Branding

Along with the rest of Ubuntu we have been updating our branding. The new logo and icon are now incorporated into our new Plymouth splash screen to freshen up our look.


KDE Plasma Desktop 4.4


KDE Software Compilation 4.4 provides the latest version of the popular Plasma Desktop.

The improved System Tray now can include various widgets, such as the improved Device Notifier, Battery monitor and our Message Indicator.

Nepomuk Semantic Search has matured greatly, you can now search through your files from Dolphin or browse the recently used timeline.

New features such as grouping windows into tabs have been added, while many smaller tweaks and changes provide for a more stable experience befitting 10.04’s LTS status

Official Kubuntu Netbook Remix release


The Kubuntu Netbook Remix has its first official release with Kubuntu 10.04. This addition brings a new way of using your desktop, geared for this popular form factor.

Amarok 2.3


Amarok 2.3 features many bugfixes, enhancements, and visual changes, such as the new main toolbar and better podcast support.

Installer Slideshow


Sit back and relax while installing Kubuntu and watch the lovely slideshow showcasing KDE applications included in the default installation. Or just use them, since it’s a Live CD 😉

Touchpad Configuration


The new touchpad configuration section of System Settings allows you to fine-tune how your laptop’s touchpad behaves.

System Notification Polish

The notifications for available codecs, required restarts and upgrade information have been further integrated into the KDE notification system, giving these notifications a seamless way to integrate with the rest of the notifications the Plasma desktop provides. They have also been optimized, taking up much less memory than before.

KDE Integration for Firefox


Firefox now integrates better with KDE, providing native KDE file dialogs as well as respecting your default choices for opening files, as set in KDE. Our Kubuntu Firefox Installer makes sure the necessary packages are installed, if you have installed Firefox manually you will need to install kmozillahelper for the integration.

GNOME Application System Tray Integration

Work has gone in to integrating GNOME tray icons into the Plasma desktop, so that GNOME apps supporting the integration will share a consistent appearance with the rest of your KDE apps.

Known Issues

  • Bug:563263 “‘No resource agents found’ error when starting Kontact/Akonadi for the first time.” Restart Kontact to work around.
