Surface Pro 4 Keyboard Backlight Not Working

  1. Surface Pro 4 Keyboard Backlight Not Working Screen
  2. Surface Pro 4 Keyboard Brightness Not Working

The problem is still the same black display, but backlight is on. I do have DVMT patch, removing DVMT patch causes panic even while having minStolenSize patch too!!! Surface guide exists only upto Sierra not High Sierra, I have Sierra working, that's why I made this post in this section!!! Can you clarify?

My reply was to your post that contained only a verbose boot photo.Your next reply shows a gendebug.sh set that contains ioreg that shows you can boot.And IGPU in ioreg there shows graphics working.What is the issue?Note: Your EFI/Clover in that attach shows you're using the 32mb DVMT-prealloc patch. Previously I suggested you set DVMT-prealloc to 64mb (or 128mb) such that you don't need that patch. Read FAQ/use google to find methods of setting it. You could also use the minStolenSize patch, but it may lead to instability.

Use at your own risk.Note2: Google may find some Surface specific guides that may be useful. IMHO, the Surface series makes a poor hack as WiFi is not replaceable, and not supported. I do have minStolenSize patch there.The problem is still the same black display, but backlight is on.I do have DVMT patch, removing DVMT patch causes panic even while having minStolenSize patch too!!!Surface guide exists only upto Sierra not High Sierra, I have Sierra working, that's why I made this post in this section!!!Can you clarify?Do I need both DVMT and minStolenSize patches same time while having Lilu and IntelGraphicsFix kext.and their combinations if any that may solve please do share your knowledge.Regards!
