Black screen on wake

[uzurka]

Hi!
I installed MacOS Monterey, using Opencore and Dortania's guide.
Everything works fine except that : When i close the lid, or suspend activity, or whatever turns of the screen, i can't get display back on wake up (open the lid or press mouse / keyboard), backlight turns on, but no display.
Audio is working, MacOS is responding (unlock with password or Apple Watch works), just, backlight turns on but no display.
Just noticed that (closing and reopening the lid multiple times make the display works back SOMETIMES (like 1 out of 20 tries)

• Lenovo Thinkpad T550, i5 5200U, Intel HD Graphics 5500,
• SSDTs builts with SSDTime,
• EFI made following Dortania's guide, no pre-made EFI,
• Tried https://github.com/5T33Z0/Lenovo-T530-Hackintosh-OpenCore/issues/48 => Not better,
• Tried igfxonln=1 => Not better,

My EFI Folder is gitted : https://git.uzurka.fr/Uzurka/Opencore-Lenovo-Thinkpad-T550/src/branch/DEBUG/EFI/OC
Actually using DEBUG Opencore & kexts

Any thoughts ?

Thanks !
Uzurka.

Was the screen ever repaired/replaced?

Nope, original one.

Attach the EFI to check!

My EFI is available here : https://git.uzurka.fr/Uzurka/Opencore-Lenovo-Thinkpad-T550/src/branch/DEBUG/
I putted it on a git so i can track the modifications, rollback if needed, and share it easily

Oh, indeed there's a geo restriction on what i'm self hosting.
Where are you from ? I'll add your country to the whitelist

US. But using a VPN. So, better to remove restriction or attach the EFI here or on Google Drive.

Restriction have been disabled for now. Should work

Yes, works now

Does this Laptop has dGPU? If so, model please and does it has any Graphics related settings in BIOS?

Do you have the CSM settings in BIOS? If yes, then what have you set it to?

Provide the original ACPI dump.
