Black screen Intel HD 530 on Mojave after patching Framebuffer

[MobBarley]

Try putting an invalid plattform id in the clover boot menu like 0x12345678(NOT in your config.plist). That will rebuild your cache. After that boot normally.

Tried - booting to desktop with invalid id but getting KP when using the correct id(0x193B0005) as mentioned by @shuhung

Just to clarify: Did you rebuild your cache after booting to the desktop?

sudo kextcache -i /

Maybe you still need the patch in properties additional to the AGDP patch?

Also worth trying:
- Renaming HECI to IMEI in ACPI Patches
- Adding PluginType = True in ACPI
- trying -disablegfxfirmware as bootflag


EDIT: I thought a bit about it, maybe also try the attached config.plist and use the two attached kexts. As next step I would try a combination of the framebuffer patches (with lilu + weg) you tried before and the agdp patch.

AWESOOOOOME - see attached Clover folder
HD530 on i5-6500 (dell Optiplex 5040) DVMT set to 96MB in EFI bios shell
Mojave 10.14.2

ACPI Patches:

Boot arguments: -igfxnohdmi
Inject Intel: Yes
ig-platform-id: 0x193B0005 Edit: You may want to add value 4 to Video Ports field
KextToPatch: prevent AGDP from loading
com.apple.driver.AppleGraphicsDevicePolicy
Find: BA050000 00
Replace: BA000000 00
SMBios: iMac17,1


3 displays working: 1 HDMI and 2x DP
fully accelerated
Whatevergreen is not used (nothing in its logs), but installed anyway, it renames DSDT

I may have to patch the DP to HDMI on port 0x5, but it works fine without, so I'll see
No Framebuffer to patch, juste used Hackintool to display information

But there is an odd issue with that: I can no longer display Twitter videos with Vivaldi web browser (works with Chrome), while before, with only two display working and 0x1912000 it was working fine...

Hey, I tried this- but getting a KP. smbios is iMac17,1 also tried with 14,2
Please see my attached config.plist
Here is Kp report.

Sorry for late reply, travelling to mainland, SKL framebuffer will not load without IMEI rename patch.

Try attached config, added IMEI rename patch.

Its okay was experimenting and learning in this time Hope you had a pleasant journey.

I tried this config with IMEI patch - getting KP
With IMEI and IGPU rename - still KP

I really doubt this has something to do with the DVMT limitation of my system - See @Anatharias post #24 he got it by setting DVMT to 64mb.

Also last time I got my working by @RehabMan patch

Comment: 0x19160000/etc, 19MB framebuffer 9MB cursor bytes (credit RehabMan)

Tried with clearing caches, yes I did that step too.

When I use the combination of FB patches - with disable AGDP - the system boots past verbose - display sleeps then reboots. Without AGDP patch it stayed with no display. Also, I tried with the kets you mentioned - but still KP
