Only drivers that you would ever need are graphics Drivers. However the FGLRX Drivers are a bit tricky. Considering that this laptop has an Integrated Graphics Card and a Dedicated Graphics Card as well. Both are AMD Make, Which makes it rather interesting. It uses something called Hybrid X-Fire.
This is supposed to automatically swtich the GPU from Integrated to Dedicated GPU as required, Much like Nvidia Optimus. However most of the people using this have not had much luck even on Windows.
So just a word of caution, You should be good with the latest proprietary FGLRX Drivers from Ubuntu Repos. If not you have an option to use the Installer from the AMD Website as well.
