[Guide] Laptop backlight control using AppleBacklightFixup.kext

Razer Blade 15 running Mojave.
i7-8750H
UHD 630 Graphics
Nvidia GTX 1060 (Disabled)
Followed the guide but no backlight control. Also upon first boost my entire screen stays black for about 3 minutes and then comes to life. If I shine my phones flashlight against the screen, I can see what's on the screen, kind of and I can log in, so it's fully booted.

Problem reporting files attached.

You forgot to put SSDT-PNLF.aml in ACPI/patched. Clover does not read .dsl files.

Also...
Your kextcache output proves kexts are not installed correctly.
All kexts you need must be installed to the system volume.
Read post #2 of the Clover guide for details:

Was still working on getting the system up and running, didn't cross my mind to move the kexts over. Also completely overlooked the SSDT-PNLF not being an aml file. Both issues fixed and the issue still remains. No control over screen brightness and a black screen upon first boot for the first few minutes and then the backlight turns on.

Updated problem reporting files attached.

As per guide, ForceKextsToLoad is only for pre-install. After install, it should be removed.

Make sure you rebuild caches and reboot.

Other problems:
- you're using the wrong Clover. The Clover you're using has a serious ACPI patching bug. Use latest RehabMan Clover as linked from the guide.
- CsmVideoDxe not recommended. Remove.
- EmuVaraibleUefi not recommended. Remove.

Also, read post #1 regarding EDID patching that may be necessary.

When everything is working correctly with your kernel cache and patching, the ApplePanels under PNLF->AppleIntelPanelA should change to ApplePanel with just the F19Txxx entry.

Kexts were installed to L/E and kext cache rebuilt in my last post, but I rebuilt cache again anyways for this time around. Updated Clover to your latest version, patched the EDID and removed CsmVideoDxe & EmuVaraibleUefi.

The good news is, I have brightness control now and the keys on my keyboard are mapped properly and work. So that's a step in the right direction!

But I still have a black screen with no backlight at all at first boot for about 3 or so minutes. I attached an updated problem reporting file for this one as well.

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.
 
RehabMan, Thanks, it works. And thank you very much for your invaluable contribution to the development of the Hakintosh community.
