I have this laptop, with hybrid graphics: 5650 and 4250, with no BIOS switching option.
I tried almost everything... and I'm tired, really tired and no time to go on trying things.
I never could use 5650 discrete card, NEVER. When trying, only black boot screen (or some boot text, too). Only once, I could boot on that card, using vgaswitcheroo... but it was slower than 4250 with proprietary drivers (I need 3D acceleration).
The driver that works OK with the 4250 (and I'm using) is Catalyst 12.4, on Ubuntu 12.04. Older drivers had artifacts, newer's don't support 4250... but neither support the 5650.
Does anybody know something about this laptop?
I bougth this laptop 3 years ago and spent a lot of money because of the discrete card... that I could never take advantage of it.
