But I still have a black screen with no backlight at all at first boot for about 3 or so minutes.

It is not a unique problem for you... others have the same issue.
No known solution at this time.

All of you with that specific problem should participate in a thread that is specifically for sharing information on that exact topic. I don't know that anyone has created such a focused thread yet. Perhaps you should do so.

There are also those with UHD, following the same guides here, that DO NOT have that problem. You might compare notes with those folks.

Beta branch merged into master yesterday (for both). Use master.

Have used this but my screen takes 2min to boot up but the external screen, w/ nvidia, boots up straight way.

Ah so odd question. I'm using Mojave with Lilu and WhateverGreen now, but when I went to patch for Brightness I needed the SSDT-PNLF.aml file but not the AppleBackLightInjector.kext. When I try to load that kext, the brightness slider is disabled, without that kext I have a working slider. Is this expected behavior, or should I submit a debug archive?
