@neocoma504 just wanted to let you know that the 3 minute black screen issue was fixed a month ago by @Fraxul. I'm currently in the process of making the patch a little safer for public release and it should be available as part of WhateverGreen soon. Thanks for all your help on this issue over the past several months. Finally we can both get back to Real Work(R) :)

PS You will need to apply the "Brightness Fix (ACPI 100)" patch to your DSDT.aml then rename DD02 to DD1F.

Also you will need to add the -cflbkltfix boot flag to enable the patch for WhateverGreen. no longer necessary.

I don't think you need "Brightness Fix (ACPI 100)"... it is incredibly unlikely that AppleBacklight has started using ACPI.
You can probably get the same "result" with "Brightness Fix" or a simple SSDT with a basic PNLF device in it.
Or continue to work on SSDT-PNLF.dsl for complete/consistent functionality.

I tried the modified PNLF.aml I already had, I tried your latest one from your repo, I tried FixPNLF AddPNLF (in the latest Clover), I tried with the AppleBacklightInjector.kext / KextsToPatch / SSDT-PNLF.aml combo and I even tried making one based on your "typical PNLF" one. None of them worked.

Maybe I needed to set the AutoMerge ACPI setting in Clover?

No such thing as Clover FixPNLF. It is config.plist/ACPI/Fixes/AddPNLF.

None of them worked.

To diagnose anything, you would need to reply with PR files as per FAQ. There is simply too many variables involved... impossible to guess what you're actually doing.

config.plist/ACPI/AutoMerge=true definitely needed if you're trying to replace/patch a single SSDT without dealing with DropOem/SortedOrder (and patching all SSDTs).

Without AutoMerge=true, any SSDT you place in ACPI/patched is treated as an add-on SSDT, instead of patched SSDT (with AutoMerge=true, and SSDTs in ACPI/patched named as they were in ACPI/origin, the pached SSDT replaces the native SSDT in the XSDT, where without, it is added to the end of XSDT).

Hi @headkaze!
Thanks a lot for this great info! That made my day. Will give it a try this week end. Hopefully we will at last fully enjoy this laptop now indeed!

We haven't released WEG with the fix yet but you can compile it yourself from here.

I've also written a little guide on how I got the brightness slider working with this here.

Compiled and used 1.2.4 WEG, still the 3 Minutes black screen isn't fixed for me.
Seems like it only fixes it on razer blades.
