Hello,
The Ubuntu forums are really the best place to get support for this kind of thing:

Most ATI graphics chips should work under Ubuntu, although depending on exactly what ATI graphics processor you have, there may be one or two extra things that will need doing.
By the way, which version of Ubuntu did you download?
