The release of Ubuntu 13.04 is less than a week away, bringing with it some refinements to the Unity interface that users either love or hate. But Ubuntu with Unity is far from the only choice for Linux lovers or those looking to avoid Windows and OS X.

In addition to the many Linux distributions such as Fedora, Debian, or OpenSuse, there is a thriving open source community maintaining desktop operating systems based on Ubuntu code but with different user interfaces. These often have whimsical names like “Kubuntu” and “Xubuntu.” While you can download the standard version of Ubuntu and apply a different user interface to it, most of these alternative distros are built with a non-Unity interface in mind from the start.

Just for fun, we’re going to take a look at the different “untus” users can choose from. In particular, we’ll focus on the “recognized flavors” that are part of the Ubuntu project—you can find links to more information on each of these and downloads on the Ubuntu wiki.
