Desktop
Mythbuntu uses the Xfce desktop interface by default, but users can install ubuntu-desktop, kubuntu-desktop, or xubuntu-desktop through the Mythbuntu Control Centre, allowing users to get the default interfaces from those flavors of Ubuntu. The only software that is included in this release is media-related software such as VLC, Amunix, and Rhythmbox.
