Benefit to Fedora

KDE is popular, feature rich and stable desktop environment used by lot of Fedora users.


Requires rebasing to the latest upstream version and preparing distribution specific patches.

Modified packages

How To Test

  1. yum groupinstall "KDE (K Desktop Environment)"
  2. set KDE as default environment + KDM
  3. login to KDE desktop

or use Fedora KDE Desktop spin

What should be checked (KDE):

  • distribution integration - phonon-backend-gstreamer
  • custom branding changes (KDM theme, KSplash theme, artwork) - for Preview Release

We are working on test plan for KDE QA.

User Experience

Modern, feature rich and stable desktop environment.


Depends on upstream KDE 4.3 release, see [1].

Custom Fedora branding depends on Fedora Artwork team!

Contingency Plan

Given how the KDE 4.3 and Fedora 12 schedules align, there should be plenty of buffer time between the KDE 4.3 and Fedora 12 releases. We are already working on importing and polishing beta version of KDE. In case of problems with upstream release we can revert to older release or we can omit individual problematic modules of this feature. KDE 4.3 could be later shipped as an update.


The Fedora KDE Destop User Guide is very important part of this feature for users. It guides users how-to use the new KDE 4 Desktop and it's targeted to both former KDE 3.5 user and first time KDE 4 users.
