Hence why I wouldn't recommend Linux to anyone using an ATI card. I consider myself pretty fluent in computers, at least with Windows, and I couldn't figure it out. Having to find that special command to get something working is just silly in 2012.
IME ATI cards can be hit or miss. Sometimes Ubuntu will install the driver you need, sometimes it won't, and other times (usually on other cards) support ended long ago.
I always stick with Intel or nVidia cards.--
