Using my AMD Radeon™ HD 8750M Graphics in 13.04

view story

http://askubuntu.com – I have been trying to get my dedicated graphics (AMD Radeon™ HD 8750M Graphics) working on my Samsung series 5 laptop. It just shows Intel® Ivybridge Mobile in the system details and gaming performance is much worse on the integrated card. Both fglrx and fglrx-updates broke unity completely. I don't mind using open source AMD drivers as long as I can activate my dedicated card (and preferably be able to switch to it only when gaming either manually or automatically). How can I activate my dedicated graphics? (HowTos)
