hello please help,Enabling Backlight on NVIDIA GTX 1060


10 posts in this topic

Recommended Posts

My notebook graphics card gtx1060 is factory shielded from the integrated graphics, only the discrete graphics.

I did the backlight control appear, but it has no effect.

In the past two weeks, I have tried various methods to enable the brightness and backlight control, but they all failed. I am so tired. Please help me!

Brightness control of Nvidia external graphics requires injecting a PNLF Device into the external graphics.
And, you need to use AppleBacklightFixup.kext

 

Also, delete NvidiaGraphicsFixup and replace it with the latest version of WhateverGreen.
Additionally, I recommend replacing other Kext with the latest version and deleting unnecessary Kext.
The 3 Kexts below are already integrated into WhateverGreen.

- CoreDisplayFixup.kext

- NvidiaGraphicsFixup.kext

- Shiki.kext

 

Add applbkl=0 boot option to disable WEG brightness patch in Config.plist.

And, SSDT-PNLF.aml will be added directly, so set AddPNLF in ACPI - DSDT - Fixes to False.

 

Modify the existing \_SB.PCI0.GFX0 path in SSDT-PNLF.aml to \_SB.PCI0.PEG0.PEGP as shown below.

External (_SB_.PCI0.PEG0.PEGP, DeviceObj)

Scope (_SB.PCI0.PEG0.PEGP)
{
    OperationRegion (RMP3, PCI_Config, Zero, 0x14)
}

Device (_SB.PCI0.PEG0.PEGP.PNLF)

 

The SSDT-PNLF.aml I modified is attached below.

Please replace SSDT-PNLF.aml with the one I modified.

SSDT-PNLF.aml

After using the new kext, the display path is modified

 

_SB.PCI0.PEG0.PEGP => _SB.PCI0.PEG0.GFX0

 

Replaced clover bootloader with version r5119.

And, I modified SSDT-PNLF.aml again.

 

Replace it with the EFI folder attached below and try rebooting.

Hello, thank you very much! I used your modified EFI. After restarting, I got stuck on the Apple interface, only the cursor. After I restarted manually, the mac startup option was lost. I now plan to reinstall the system. Sorry that my English is not very good, some descriptions may be inaccurate.

I’m not sure if this will work for you, or if it will destroy your operating system.

It recently worked for me on macOS Sierra 10.12.6 in order to get the brightness slider working properly:

Try replacing your High Sierra files with the corresponding Sierra files by following the instructions in this thread.

(Don't forget to rebuild permissions/cache afterwards.)

You should be then be able to vary the brightness with the slider.
