HD Graphics 655 & i3-8109u : no acceleration & black screen without -igfxvesa arg

[frankynov]

Hello,

 

I believe my issue is similar to the other topic here but I didn't want to pollute it as it is slightly different config, let me know if I should merge it

I am using a nuc-like config, a Trigkey Speed S1 Mini PC, which is a clone of another one called Beelink SEI8. Not an ideal config I have to admit as the documentation is almost inexistant. On the other hand, the BIOS setup has pages and pages of tons of content that I never saw before, quite positive.

 

So, I have an issue with the graphics acceleration on that machine. Being a Coffee Lake and Iris 655 and similar to the other topic above, I believe it is a laptop CPU embedded on a desktop board. Dortania guide mentions regularly that we should consider the NUC as laptops.

I am using a MacMini8,1 SMBIOS as recommended too, with OpenCore and kext's from July 2022. The machine has 2 HDMI ports, I connect 1 HDMI screen via an HDMI cable with no adapter involved.

Here is my frame buffer settings that allow me to boot with these parameters in low performance mode : -v keepsyms=1 debug=0x100 -wegnoegpu -igfxonln=1 -igfxvesa

Whenever I remove the -igfxvesa boot argument, I'm getting a black screen. I can type in the blind my password, open a terminal and reboot so macOS works, but no screen at all.

In Hackintool I can see the following regarding the GPU/Screen :

 

Regarding the screen :

 

 

And the connectors. I don't like the Red line on the first input, but I have to admit I don't know how to read that. Hackintool is a bit confusing for someone like me who don't decompile ACPI code on a daily basis

 

 

I would really appreciate some help here ! For sure the config is not easy, I did multiple hacks before including AMD Ryzen and it was quite straight forward, but this one is giving me so much headaches !

 

Thanks !

 

Regards,

Just realized that it might help with the following content.

You will find my EFI (without the serial numbers) with the IOReg extract and system preferences.

 

EFI : EFI with all kext

IOREG : IOREg and system info extract

 

Also, a photo of the BIOS regarding the graphics section.

Test this EFI EFI.zip,if start new ioreg .
But is it a desktop or laptop ??

Hi Baio,

 

Many thanks for trying to help me.

I gave a go on the EFI folder, reset NVRAM, but unfortunately it doesn't boot at all, looks like it's stuck after SMCSuperIO.

It is physically a desktop - there is no builtin screen but I believe it is using a CPU/GPU combination that is usually found on laptops.

Can you post your system's specs, especially the exact model of CPU please?

 

Hello Hervé, bonjour !

This is what I get from the HWiNFO64 on Windows, and I have uploaded the full HTML report here if you want to check out : 

 

 

CPU Name : Intel Core i3-8109U

Let me know if you need further info !

 

Thanks

Hi everyone

 

So I have updated all my kext to the latest stable versions, also OpenCore to 0.8.3.
Sadly that didn't improve my issues with the graphics acceleration.

 

With all the details I posted above, would someone be able to have a look on how I can maybe progress on that ?

Again don't hesitate if you need further info, dumps, etc.

 

Thanks !

How can you propose a EFI folder not knowing hardware? 😮
