Mint 13 Cinnamon ran graphics exclusively on Intel Ivy Bridge HD 4000 (Intel Core i7-3720QM cpu) since I did not install additional drivers for my graphic card (AMD Radeon HD 7970M). Now I'm running Mint 14 Cinnamon.
Mint 14 Cinnamon has an open source AMD/ATI display driver automatically installed during system installation. How do I remove this(all) driver(s) for the graphic card - or disable the graphic card - to run graphics exclusively on my Intel Ivy Bridge HD 4000? I only use my graphic card when booting into Windows - I do not want it running hot in Mint for no purpose.
Please don't tell me to uninstall xserver-xorg-video-ati (which I've obviously tried and tried again with no luck) or something like that without a (very) precise description, thanks.
(First time in six years with Linux that I didn't find my answer somewhere. Everybody seems to want the opposite of me this time).
