I've done exactly that on my i7 laptop for ages now. It usually runs it's own 1920 display and an external monitor of same resolution, and has this hardware: 00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06) 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus XT [Radeon HD 8870M / R9 M270X/M370X] I use the intel video driver and it's been more than a year since I built a kernel with radeon :-) The intel gpu manages full HD video and funky plasma5 effects just fine at a fraction of the battery usage of the radeon. These days I ask myself: if I'm not gaming at insane frame rates, or using cuda, then why do I need the radeon power at all....? -- Alan McKinnon alan.mckinnon@gmail.com
