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" driver, 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)...
At the time of writing, I am using Ubuntu 13.10 ("Saucy Salamander"), however as per usual, I will be upgrading to Ubuntu 14.04 LTS ("Trusty Tahr") the moment it is available (I typically upgrade to each new version, .04 LTS and .10).
Being someone that is semi-competent with Terminal, I have "toyed" with this in the past, but the last time I did, Ubuntu would boot-in to a plain black screen after login (i.e. I could see the login screen, I could login and then the screen would go completely black) and I had to run a whole heap of commands from the recovery Terminal (at boot) in order to get things running again.. Most likely however, it was because I "broke" something when trying to setup my Radeon HD 6630M - I did it using a whole page of commands I found via Google, none of which was specific to my laptop.
Any help in sorting things out would be greatly appreciated...
