your acpi/patched folder is very wrong, no need for all those files in there, best to read up on the patching guide:

Makes no difference if I remove them, I have compiled (disassembled first) all but one of the DSDT/SSDT I dumped from clover with 0 errors. I have not patched any of them, and as far as I understand it shouldn't be needed with the brightness fix? Or could some patch maybe fix make it work? Thank you in advance.

config.plist -> InjectKexts should be set to Detect

SSDT-PNLF.aml is missing from acpi/Patched folder

config.plist changed with Detect and SSDT-PNLF.aml added in ACPI/Patched. I patched the DSDT with the recommended patches from the laptop section. Nothing changes. I cannot boot without injecting Nvidia in config.plist. I cannot see the card in system info but I guess it is running. I have not tried to disable it. Best regards.

what patches did you do in your DSDT?
 
what patches did you do in your DSDT?
"Rename _DSM methods to XDSM"
"IRQ Fix"
"SMBUS Fix"
"OS Check Fix (Windows 8)"
"Add IMEI"
"RTC Fix"
"Fix _WAK Arg0 v2"
"USB3 _PRW 0x6D (instant wake)"
 
Seems like nothing I do makes a difference.

-Completely made sure I had no brightness fixes.
-Removed everything from ACPI/patched folder excluding SSDT-PNLF.aml.
-Tried to inject EDID from config.plist/Graphics. I use rehabmans clover 4701 with the hd 630 config.plist
-Tried to remove Whatevergreen.kext incase as I've read that it already includes the kext Im trying to use.

Could it be that my display is not compatible? Is it maybe necessary to disable the dGPU (GTX 1060 6gb) to make brightness work? I have the slider and hotkeys are working as well (although not on the correct key).

The only thing I do not understand well is the PWM MAX section. Could a correct PWM value make it work or is it more a matter of brightness levels?
