After many headaches, I’ve installed Ubuntu Gutsy Gibbon 32 bits on my little desktop (Lenovo 3000 N100 0768DKU which supposed to be x86_64; the fact that it is, but Ubuntu amd64′ install is VERY LAME, and crashes at 15% of filesystem detections), and here is my desktop, working fine and beauty.

ps: it was made using recordmydesktop and mencoder, to convert ogg to avi.
