I have a 10.10 install on a MacbookPro 5,3. Ubuntu uses quite a lot of power and has a really low battery life. I've already disabled bluetooth and the iSight camera. The Macbook has two different graphics cards.The "big" one is a GeForce 9400M,but I don't have a clue about the "small" one (maybe someone could tell me how to figure out which one it is?). Is there a way to tell ubuntu which one to use? Usually a change to the smaller one save me 2-3 hours of battery on OSX.

Can you please update your question with what the two graphics cards are. Some cards are know to run very hot with some drivers causing low battery life and potentially permanent hardware damage. If we know what the cards are we can suggest alternative drivers. –  trampster Apr 7 '11 at 22:47
