How to manage two video cards on a laptop (ATI and Intel)?

Solution 1:

I know this is not a concrete answer, but I've found a couple links that might be able to help you out:

1. Ubuntu Documentation for Hybrid Graphics

2. Ubuntu forums discussion on the topic.

3. This one is for users with less experience in kernels etc.

I had found other links late last year - if I can find the articles again I will add them to my answer :)

Solution 2:

Hybrid graphics has improved a bit lately. The Catalyst drivers provide a login/logout switch. Have a look at these websites:
