Hello

Today I reinstalled system and I created SSDT for my i7 2820QM but I still have a problem with graphics card, on this moment i try boot with thats flag:
nvda_drv=1 npci=0x2000

nvda_drv=1 npci=0x3000

System Only Start with nv_disable=1

Try the nVidia Web driver.

 

You can also remove the PCIRootUID=0 from your boot plist, that's the default value used by all bootloaders.

I Install Nvidia Web Driver, but it not work.

In verbose mode i don't see any errors or warnings.

When I try run system without Nv_disable=1 I have all logs as a normal start but instead normal system I have black screen.

Do you have any idea ?

[Cyclib]

I have a new info about it. System work good because i hear some sounds: Volume change for example. It is a problem with internal display

[Hervé]

What if you put the computer to sleep and wake it? Assuming you've disabled hibernation of course...

 

You may need to obtain the EDID info for you screen, then inject it into OS X.

[Cyclib]

Could you help me with EDID an inject it in OS X ? Do you have any guide for this ?

[Hervé]

I'm going to prepare a dedicated thread on EDID injection and will post the link. It'll be nothing new, just a copy of existing stuff readily available on the web...

 

Your problem sounds similar to something I previously encountered with an old HP G72 laptop...

 

You could check your graphics acceleration status despite LCD screen issue by sharing your screen. Boot with GE=No and go to System Preferences...->Sharing and activate Screen Sharing. Your system is then available through vnc at its assigned IP address (vnc://x.x.x.x). If graphics acceleration is indeed running when booting with GE=Yes, you should be able to see GPU model and VRAM in About this Mac + all supported features in DVD Player help menu->show supported features through the VNC access.

Or try use Clover bootloader with this option in Graphics sections:

- DualLink 1

- Inject NVidia Yes

- NVCAP 0400000000000100FE0000000000000700000000

- NvidiaGeneric Yes

- NvidiaSingle No

 

I think, this works also without DSDT.aml

[Cyclib]

Ok now, i connected by VNC with nvda_drv=1 in About This mac i see Nvidia Quadro 1000m but only with 1gb ram but i think that is cosmetic error.

 

I connected to laptop from my desktop hackintosh.
