[Florent Bajrami]

CPU: Intel Core i5 1040T CPU @ 2.00Ghz

MOBO: Lenovo

RAM: Dual Channel DDR4 2x4 - 2666Ghz

GRAPHIC: Intel UHD Graphics 630

Hi all,

I'm struggling with the lenovo for about two months now reading in the forums trying to fix this graphic issue.

Usualy I'm not a spoon feeder I researched in the site but didn't have success to fix my issue so if you guys have time to help me I will appreciate it.

Issue:

Tried to get full Graphic acceleration on the Big Sur 

Only way to boot in the OS is with the laptop config.plist and as a device id = 0X9BC80003 (empty framebuffer) and no AAPL, platform id

Tried with the desktop platform id 3E9B0007 got in internal black screen > External HDMI got the perfect picture with fixed vram memory

Tried platform id 3E9B0007

device-id 0X9BC80003 > no change got 7mb

Tried with framebuffers > changed connector from HDMI to LDVS to force to boot in the internal Display > no joy

Tried with various of the settings didn't have a success
