Intel UHD 620 graphics

[lyricorpse]

Brightness controls not expected to work with invalid ig-platform-id (working graphics is a pre-requisite).

32mb DVMT patch not needed when using IntelGraphicsDVMTFixup.kext. Do not use both.
You may also want to try different ig-platform-id values (such as 0x59160000).

Not working... So far, it seem that we still don't get the important error information. How can we trace that? Any thoughts?
Also, it seems that I am having the same problem mentioned in this post https://www.tonymacx86.com/threads/dell-xps-9360-kabylake-r-high-sierra.239368/page-4

But even if I tried using `setup_var` to modify the DVMT-prealloc as mentioned in https://github.com/the-darkvoid/XPS9360-macOS, it just broke my booting. Maybe I should not use 128 mb for my Inspiron 7370...

You cannot use setup_var until you determine the DVMT-prealloc index from an IFR extract.
Setting BIOS variables with setup_var without first verifying the correct index/values can brick your computer.

I see. Thanks for this information!

Correct settings are already in the plists provided by the guide:

Did you ever figure out how to get graphics working on your uhd620? Ive got a very similar setup and am in the same boat.

Nope. I give up for now and am waiting for the official support from Apple when they sell 8th gen laptops...

I installed Lilu.kext IntelGraphicsFixUp.kext FakePCIID.kext FakePCIID_.kext and FakePCIID_Intel_HD_Graphics.kext then i used Fake ID for IntelGFX (0x19168086) and put 0x19160000 for the ig-platform-id

dont forget to reboot with an invalid platform id (0x12345678)
run sudo kext cache -u /
then reboot with the valid id (0x19160000)

THANKS BROTHER.. "0x19160000" ITS WORKS..

Borrowing this thread since I have a similar issue with the same card.

I have been trying all the different invalid platform ids and fake-ids in this thread but can't get it to load the graphics kext...
Would be very appreciated if someone could give a hint at which part (dvmt-prealloc, etc) that's not working.

I'm using Whatevergreen now, but I haven't been any successful in using the older kexts either.

You should not expect the graphics kexts to load when using an invalid ig-platform-id.
Must use a valid ig-platform-id.
