How do I use the Intel card in my dual video card laptop?

http://askubuntu.com – I am having some issues with my Intel 4000HD driver. I have installed Catalsyt 12.11 beta and I am running on Ubuntu 12.10. I am not experiencing any major problems at the moment. The only thing I know is that I am always running on my high performance card and that my Intel doesn't have the right drivers even if I took the driver I found in a forum that was explaining how to configure my switching graphic card system on my computer. Thanks for your help! (HowTos)
