Intel HD 630 Display Flicker/Ghosting

[j4ys0n]

Hey guys,

I'm nearing completion on my new hackintosh build with Mojave. There's just one issue I can't seem to resolve. I've been searching this forum and google all day, and no dice. There's some ghosting or flickering on the display. Maybe it's framebuffer related? I've seen the issue mentioned here, some people had success with just setting to iMac14,2 in SMBIOS. That didn't work for me.

Relevant specs:
Gigabyte Z270N-Gaming 5 (mini ITX)
Intel i7 7700k
Intel HD 630 graphics

Only 8GB RAM for now, going to make this my main machine and swap the 32GB in my current main machine once this is working. Also planning to add an AMD RX 580 after I get this working, but that's for another day

config.plist attached.

I've tried the following:
Boot with -disablegfxfirmware (didn't work)
inject FakePCIID_Intel_HD_Graphics.kext (didn't work)
Devices IntelGFX Fake ID: 0x59168086, also tried 0x59128086 (didn't work)
Graphics: InjectIntel (no difference)
ig-platform-id 0x59160000 (this resolves the pink screen tint) I also tried 0x59120000 and empty (results in pink screen tint)
SMBIOS: iMac 14,2 - 18,2 -18,3 - 18,4 (none seem to make a difference)

I've also tried various combinations of the above.

Injecting the following kexts (all latest versions):
AppleALC.kext
AtherosE2200Ethernet.kext
FakePCIID_XHCIMux.kext
FakePCIID.kext
FakeSMC.kext
Lilu.kext
USBInjectAll.kext
WhateverGreen.kext

I came across this post: https://www.tonymacx86.com/threads/guide-intel-framebuffer-patching-using-whatevergreen.256490/ (where I got the good ig-platform-id from) but I can't decipher exactly what I would need to do (if anything) to fix the flickering.

Any help is greatly appreciated!

Cheers

I've been playing around with @headkaze 's framebuffer patcher for the last few hours, no luck.

I've been trying to figure out how to use -igfxdump and -igfxfbdump i added those as boot args in config.plist but there's no file output in the root directory.

I've also been trying to follow the instructions here https://www.tonymacx86.com/threads/guide-intel-framebuffer-patching-using-whatevergreen.256490/ and here https://www.tonymacx86.com/threads/release-intel-fb-patcher-v1-5-9.254559/ but i'm not an expert in patching kexts. Not to complain, but I'm a software engineer and this is far from clear. Screen shots would go a long way.

If anyone can help here it'd be greatly appreciated. I'll be doing the same thing on a similar machine next. (Gigabyte Z170N-Gaming 5 w/ i7 6700k).

I'm happy to do that, and I'll throw some crypto your way. I apologize if that came across as passive aggressive.

I'm just not sure what I'm actually supposed to do here.

Do i just need to enter the right values to patch in devices/properties in config.plist, do I need to produce a new whatevergreen.kext using the dump from -igfxdump or -igfxfbdump or both?

No problemo. I do this to give back to the community who have helped me so thanks anyway.

Don't bother dumping your fb data just use the Framebuffer menu in FB-Patcher.

Thanks. What do I do have to do though? Is entering the patch values in config.plist sufficient? I tried doing that earlier (possible I did it wrong).

I'm on a mobile right now so it's kinda awkward but bare minimum you need an ig-platform entry. You can export to your config.plist from FB-Patcher but if you feel more comfortable just generate the patch and paste it in manually. Or just use Xcode and enter the data that way. Whatever you find easier.

I also use i7 7700K with HD630


Here's my configuration:
Remove FakePCIID_Intel_HD_Graphics.kext and just use WhateverGreen.kext
Boot: -disablegfxfirmware
Devices:
1. IntelGFX: 0x59128086
2. Click UseIntelHDMI
3. Add Properties: (This is how I fix pink tint)

a. Device = IntelGFX
b. Key = AAPL,GfxYTile
c. Value = 0AAAAA00
d. Value Type = DATA​

Graphics:
1. InjectIntel
2. 0x59120000
SMBIOS: iMac 18,1

This configuration works perfectly if you don't have dual monitor. If you have dual monitor, you should connect the second one after boot, or both screens would still flicking

Spooky dude. We have like the same exact build I added a rx580 just 4 days ago! I had to switch to SMBIOS 17,1 from 18,3 when I took out my gtx 1060 to us the HD630 for a while. I recommend you do that first and see if the problem persists.
