I have a DELL laptop with 2 GPU, an Intel integrated and high performance of AMD radeon HD a 6470m, but ubuntu does not detect HOWEVER as I should and make sure you have the 2 active at the same time which proboca overheating equipment and the battery lasts less than 40 minutes. I installed the catalyst drivers but the system becomes unstable and heated haun more. hope and help me solve this problem with either software or disable any GPU from AMD since ubuntu as give yourself the BIOS is not possible. caracteristeicas of the PC: Intel Core i5 CPU with integrated GP (HowTos)
