If you were to try out Linux other than Ubuntu and Fedora, the two leading Linux distributions in my humble opinion, then you should try out Knoppix Live CD. It contains automatic hardware detection, support for many graphics cards, sound cards, SCSI and USB devices and other peripherals. In addition, it can be used as a desktop, an educational CD or a rescue system. If you are new to Linux the Knoppix Live CD. It’s a good way to dabble with Linux without installing over your existing operating system. The latest Knoppix Live CD was released on February 08, 2009 with version 6.0.
