IGPU framebuffer and sleep broken with Clover Bootx64 (> rev5117)

[jayw8888]

I tried to update my Clover from v4690 to the current rev5122. While I noticed it booted fine, the system will reboot or hang after each time it woke from sleep.

I observed the boot sequence and noticed the following lines in the verbose feed.
Lilu patcher: @ failed to solve __ZN31AppleIntelFramebufferController17IsTypeConlySystemEv, err2
WhateverGreen igfx: @ failed to route IstypeCOnlySystem
.....
[IGPU] Graphics driver failed to load: could not register with Framebuffer driver!

So I reverted back to the EFI folder from rev4690 and all was fine again.

I experimented various versions of the Clover available online eg 5104, 5108, 5111, 5116, 5117, 5118, 5119, 5120.

It seems that there is a difference at 5116 to 5117 that allows the frame buffer to be loaded correctly. Everything from 5117 upwards did not work correctly and gave the same error.

These are what I tried with the versions above 5117, remove the ig-platform-id (currently set at 59120003) and remove inject Intel. >> No good

So I tried to swap out the BOOTX64.efi while maintaining CLOVERX64 at rev5122. That also works when the BOOTX64 is returned to rev5116. Sleep and wake is fine and frame buffer is loaded correctly.

I also updated WEG and Lilu to the latest version with no changes either. Still having the same issue with BOOTX64 above 5117.

Perhaps some of you who have better knowledge of whats under the hood of clover can help
- Is it OK to mix BOOTX64 with another version of CLOVERx64?
- What is the cause of this "TypeC system" error? Did I miss some new settings?
- Why does the BOOTX64 cause the framebuffer NOT to be loaded?

My config.plist is attached.

My setup:
- z370 with i7-8770k
- High Sierra 10.13.6
- RX580 with 1x 4k and 2x HD monitors
- imac18,3
- boot arguments: -v darkwake =10 -disablegxffirmware



Thanks in advance..

Hmm, I get the exact same lines using OpenCore. Haven't been able to track down why yet.

Same log with OpenCore on big sur.
I have two displays and only one of them works at the same time, I've tried everything but no luck.
only using SMBIOS 'iMacPro1,1' two displays get working with glitchy effect.

also, SMBIOS iMac18,1 is not working for me(displays turn off on mac's login screen startup), (it works with Catalina, but not big sur). I'm currently using 'MacBookPro14,3' SMBIOS.

*I have not dedicated GPU.
*Two ports I'm using are DVI and HDMI.

Hello - I've got the same issue upgrading from catalina to big sur using oc 6.6 on intel nuc7. Did you ever fix it ?
thank you
