Hi, im fighting for about a month to my internal screen get to work, but no result.
On HDMI it works good, with acceleration, but eDP screen is always black after boot, it's even detected as color lcd (i injected EDID with hackintool).
I can change backlight and i see how its darker and brighter, but it stays black all time.
My specs: i5-7300hq, Intel HD630, Full HD eDP screen.
My ports presenting:
[0] busId: 0x00, pipe: 8, type: 0x00000002, flags: 0x00000098 - ConnectorLVDS
[2] busId: 0x04, pipe: 10, type: 0x00000800, flags: 0x00000187 - ConnectorHDMI
[3] busId: 0x06, pipe: 10, type: 0x00000400, flags: 0x00000187 - ConnectorDP
Alldata:
00000800 02000000 98000000
02040A00 00080000 87010000
03060A00 00040000 87010000
I tried many ready EFI folders for same model from github etc, but none of them fix the screen, how should i patch these buffer to use internal display?
Framebuffer ports are listed
@0: 0x0
@1: 0x5
When i use patches the screen still black, it only work with igfxvesa=1 so i guess it's problem with ports after whatevergreen load:
AAPL,ig-platform-id 00001B59
device-id 1B590000
framebuffer-fbmem 00009000
framebuffer-patch-enable 01000000
framebuffer-stolenmem 00003001
framebuffer-con0-enable 01000000
framebuffer-con0-alldata 00000800 02000000 98000000 < - I tried every busid for con0 with no result (0001, 0002, 0003, 0004 etc) and (0201, 0202.. 0301 0302..)
framebuffer-con1-enable 01000000
framebuffer-con1-alldata 01050A00 00080000 87010000
Tried also con0 as 0105, 0204 and 0306 busid but no result.
On some busid's internal screen is black but there are some glitches and lines visible, but no output on any busid or index.
I run macos ventura.
Laptop is Lenovo Legion Y520 15-IKBN with FULL HD eDP LCD 60Hz.
I deleted kexts from EFI to be able upload attachment.
