I found this on wiki:
For most users it won't be necessary to go into installation and configuration details of the driver. Ubuntu 8.04 (Hardy) provides a notification saying that there are restricted drivers available. You just have to go there (Restricted Drivers Manager) and enable the "ATI accelerated graphics driver". Ubuntu will then install and configure the driver for you. If this does not provide the optimal solution you were looking for, please read ahead"
I did not know about the "Restricted Drivers Manager" I will try this next.
