At the moment my Sony VAIO VPC-CB15F is using only my integrated Intel HD Graphics 3000 graphics card with the "X.org X server - AMD/ATI display driver wrapper from xserver-xorg-video-ati" drivers, however I would like to: a) Get my AMD Radeon HD 6630M graphics card working and; b) Use the Radeon HD 6630M exclusively (i.e. not use the integrated Intel HD Graphics 3000 graphics card at all).
I'm not worried about whether it's propriety or Open Source drivers, just as long as I am either using my Radeon HD 6630M exclusively or I am able to switch between the two effortlessly (though as I said, I'd prefer the former)...
I previously asked this question back when I was using Ubuntu 13.10 ("Saucy Salamander"), however I've spent most of the year away from a computer with work and in the process, I even forgot that I had asked it!
Anyway, I'm now running Ubuntu 14.10 ("Utopic Unicorn"), and the instructions below do not work under this version of Ubuntu - even before I deviated (see below), I get errors and when I get to the (Ubuntu) version-specific commands, my attempts to use the same commands changed for Utopic Unicorn throw-up even more errors!
Any help in sorting things out would be greatly appreciated...
