Well u can update the drivers from the internet.. by teh way I advise you to use gOS, instead of ubuntu, it's based on Ubuntu 7.10, but it is a million time better looking, it has the layout of Mac OS. Check it out. Anyways, try updating your softwares and drivers. I didn't have any problem using it.
