I have a HP Pavilion dv7-6135dx. It has Intel HD 3000 Graphics and ATI Mobility Radeon HD 6490m. i cannot seem to get the intel Graphics to load correctly. The information in system profiler is as follows:

Display:

Type: GPU
Bus: Built-In
Vram(total): 64 MB of Shared System Memory
Vendor: Intel (0x8086)
Device ID: 0x0116
Revision: 0x0009
Kernel Extension Info: No Kext Loaded
Displays:

Display:

Resolution: 1024x768
Pixel Depth: 32-bit Color (ARGB8888)
Main Display: Yes
Mirror: Off
Online: Yes

The resolution should be 1600x900 (i have tried GraphicsMode=1600x900x32, no avail).

The ATI card is as follows:

Unknown:

Chipset Model: Unknown
Type: GPU
Bus: PCIe
SLot: Slot-1
PCIe Lane Width: x8
VRAM (total): 256mb
Vendor: ATI(0x1002)
Device ID: 0x6760
Revision ID: 0x0000
ROM Revision: 113-B7710C-176
EFI Driver Version: 01.00.318
Displays:

Display Connector:

I have loaded many different kexts (2011 MBP Intel HD Graphics, and ATI Kexts). I have also added my device id to different kexts.

Is there any hope? I was thinking about trying to physically remove one of my cards in hopes that i can get the other to work. Anyone know of anything better?

I have the same problem as you. I have a HP laptop with switchable graphics. In the BIOS, you should be able to change the graphics setting from 'Hybrid' (which means 'switchable') to either 'iGPU' or 'dGPU' (integrated/discrete graphics respectively). Attempting to change this setting does not work. The laptop will revert to Hybrid once the BIOS setup menu is saved and exited. If you select dGPU, the system fails to even exit the BIOS setup, it seems to hang on a black (blank) screen.

These video settings can be found in the advanced menu in the BIOS setup. The advanced menu is usually only accessible by repeatedly tapping 'a' after selecting to enter BIOS setup.

Let me know if you have this very same problem.

I pressed a after pressing F10 to boot into boot setup. It started beeping and i saw no advanced features. I did find a switchable graphics item. I could either pick "fixed" or "dynamic".

Did You can try to install Snow Leopard?

May be should You will try Lion?
On my laptop (Dell Vostro3350), the system was properly set.
Video HD3000 show is correct.

I had great difficulty with Snow Leopard.

You must use correct DSDT

You cannot switch to ATI card in OSX. The DV7 series laptops have muxless GPU switching in which the display is connected permanently to the Intel card.

Intel HD3000 (0116) works in Lion & SL 10.6.8 OOB, just make sure that you're using MacbookPro8,1 smbios.plist..

Only the thing needed now is to be able to power off the ATI card via DSDT so that it does not draw power.
