[Guide] Disabling discrete graphics in dual-GPU laptops

I think I did it correctly. Is there a way for me to make sure it actually stopped my GeForce from running?

Read post #1, "Problem Reporting".
 
Here are my materials; I'm pretty sure I didn't miss anything.

Your ioreg shows no discrete graphics on the PCIe bus.
So... success.

You have a lot of other things to fix though:
- USB not configured correctly (custom SSDT for USBInjectAll needed)
- power management not implemented
- AppleLPC not loaded (ACPI patch needed)
 
So I've been following your guide and everything worked out perfectly. NVIDIA card was disabled, saving me hours of battery life. Thanks so much for the guide!

But I'm experiencing a very strange problem, maybe you'll know more about this.

I can only use my iGPU when I use the Switchable Graphics option in BIOS/UEFI. So when I don't have that enabled, the NVIDIA card gets forced for MacOS, which either means no video output, or using software rendering (nv_disable=1).

The Switchable Graphics option is fine as it is in Windows or Linux, but in MacOS it just resets itself to disabled everytime I reboot macOS..

Is there any way to fix this, or is there another way to force iGPU instead of NVIDIA for MacOS?

I've made a separate Thread for this here: https://www.tonymacx86.com/threads/...n-in-bios-keeps-resetting-after-reboot.223516

Thanks!

I replied in the other thread.
 
Does anyone have working/patched SSDT/DSDTs that disable the NVIDIA GPU for the ASUS ZenBook UX510UW-RB71? I'm sure I could do the patching myself once I get the laptop in the coming weeks given something I have on eBay sells well, but if someone has already done it that'd save me some time. If not specifically for the UX510 series of ultrabook, does anyone have a working set of patched SSDT/DSDT for the GTX 960M? Thanks in advance.

Disabling the dGPU is covered in post #1.

And... You should probably read the FAQ...

That's not what I asked (for). I was asking if someone with a similar setup could share their DS/SSDT edits so as to save some time and possible frustration. Yes I know you detail it in post #1, but what if someone doesn't want to do it themselves? The laptop I want is selling quite well, so chances are the same edits from others will work well for me as well.

Two problems with your request:
- off-topic
- not advised

You cannot share ACPI files between computers. The reason is documented in the ACPI patching guide:
https://www.tonymacx86.com/threads/guide-patching-laptop-dsdt-ssdts.152573/

And your query/request for files in this thread is clearly off-topic.
