Integrated and Discrete Graphics, Working Together

[ccx4700]

Hello,
Though I struggle to get this working.

I encountered a similar condition to you on GA-Z68MX-UD2H-B3+HD4000+GTX560Ti.
With IGPEnabler=Yes and GraphicsEnabler=Yes, chimera said "nvidia rom patching failed", and boot failed.

But, I succeeded to boot with IGPEnabler=Yes and GraphicsEnabler=No.
In spite of GE=No, QE/CI of GTX560Ti works.
I think Fermi cards needs GE=Yes to work, so I don't know why this settings effective.


All of my graphics related settings are below.

Environment
MB : GA-Z68MX-UD2H-B3
IGP : HD 4000 (i7-3770) (used Intel Graphics Patch for 6series+ivy mixed )
GPU : GeForce GTX560 Ti (GF114)
OS X : 10.9.3
bootloader : chimera 3.0.1
smbios.plist : imac13,2

UEFI
Init Display First : IGFX
Internal Graphics : Enabled
Internal Graphics Memory Size : 64M
DVMT Total Memory Size : MAX

org.chameleon.boot.plist
GraphicsEnabler=No
IGPEnabler+Yes
IGPlatformID=0166000A

Hello,

Finally I'm not pursuing this because of some software incompatibility with that sort of hybrid setup.

I use a VJ software called "VDMX" and whatever I do it will use ONE gpu at a time, and of course the less powerful one (intel HD) by default.

They advise not to use mixed GPU brand with their software due to drivers issues.

I think that when heavy duty video / graphics work is involved, it's a good general advice to stay with the same brand/model within your setup.

Too bad, as the intel HD would be ideal for GUI only stuff (software interface) when the GTX could output the live rendering... But can't get this to work

I'm falling back on a Matrox triplehead2go output splitter system (expensive as hell, but does the work).


[EDIT] Didn't mention that this stoopid Intel HD cannot output DVI Dual Link, so no 27" 2560x1440.
Have to use HDMI with expensive special cord apparently.

Cheers all.

So.. I've got this working but not consistently. When I reset, it reverts back without QE/CI.

Then I have to reapply my MultiBeast settings which seems to only work sometimes. Anyone have any idea why this happens?

Thanks in advance.

Framebuffer is correct, MEI is correct, AppleIntelSNBGraphicsFB.kext is not loading. Suggest a clean install.

can i just reinstall the kext?

NVM, did clean install. still have the same issue. No QE/CI. Here are the requesed files again:

Same problem. No other ideas.
