The world of open-source desktop revolves mainly around Linux. Still, there are several other players that you may want to consider as your desktop distribution.

Another one is PC-BSD, a desktop oriented flavor of the UNIX-based BSD operating system. With the recently released Galileo and KDE 4.2.2 environment, PC-BSD is definitely worth testing.

The first steps would be to choose language, keyboard settings and timezone.
