I've done exactly that on my i7 laptop for ages now. It usually runs |
27 |
it's own 1920 display and an external monitor of same resolution, and |
28 |
has this hardware: |

|

00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core |
31 |
Processor Integrated Graphics Controller (rev 06) |
32 |
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. |
33 |
[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 |
36 |
built a kernel with radeon :-) |
37 |
|
38 |
The intel gpu manages full HD video and funky plasma5 effects just fine |
39 |
at a fraction of the battery usage of the radeon. These days I ask |
40 |
myself: if I'm not gaming at insane frame rates, or using cuda, then why |
41 |
do I need the radeon power at all....? |
