“Currently, Ubuntu recognizes six official variants. Three —
Edubuntu, Mythbuntu, and Ubuntu Studio — are defined by their
purposes. Specifically, Edubuntu is focused on education, Ubuntu
Studio on multimedia, and Mythbuntu on MythTV.“Three other official variants are distinguished primarily by
their choice of desktop: Lubuntu uses LXDE, Kubuntu KDE, and
Xubuntu Xfce. It’s within the three desktop-defined variants that
general users can look for alternatives to the main Ubuntu
interface of Unity on top of GNOME.”
