[Unsolvable] Black screen when waking from sleep on Mojave 10.14.3, Lenovo G50-80, Broadwell HD 5500

[JackLeeu]

0x16260006 + AppleIntelBDWGraphicsFramebuffer : boot loop
config1.plist: boot stuck at fUseGPUBusy = 0
config2.plist: boot loop, or stuck, randomly

Using 0x16260006, I will get a frozen screen (external screen) but can move the mouse when waking from sleep, I will use another ig-platform-id (0x16160002 )

Do I need to patch EDID again (I have done this before but not succeed) like this post https://www.tonymacx86.com/threads/solved-black-screen-on-wake-from-sleep.237093/ ?

0x16260006 +

Name : AppleIntelBDWGraphicsFramebuffer
Find : 8945C839C7764F
Replace : 8945C839C7EB4F

= still black screen

9.2 KB config.plist got boot loop

I have already applied RTC fix in DSDT patching, see here (linked at #1)

Thanks for your effort.

Use 0x1616002 with inject EDID (try also inject Intel enable, if don't work disable) and this custom EDID:
00FFFFFF FFFFFF00 30E4A404 00000000 00190104 951F1178 EAE44594 59568F28 1D505400 00000101 01010101 01010101 01010101 01012E36 80A07038 1F403020 350035AE 1000001A 00000000 00000000 00000000 00000000 00000000 00FE004C 47204469 73706C61 790A2020 000000FE 004C5031 34305746 362D5350 423100DE

Did you mean 0x16160002 ?
Could you please copy EDID text instead of picture?
Also, do I need VenderID & ProductID?

EDID with inject intel enabled: still black screen
EDID with inject intel disabled: still black screen

 

[JackLeeu]

Do you select Inject EDID?

Yes, of course.

 

[JackLeeu]

Can you use windows on your computer to get your personal EDID?

Sorry but could you explain where can I find EDID on windows?

Okay I got it from Intel Graphics Control Panel:

Raw EDID:
00 FF FF FF FF FF FF 00 06 AF ED 37 00 00 00 00
00 17 01 04 95 22 13 78 02 D1 15 9E 59 53 9B 27
1E 50 54 00 00 00 01 01 01 01 01 01 01 01 01 01
01 01 01 01 01 01 78 37 80 B4 70 38 2E 40 6C 30
AA 00 58 C1 10 00 00 18 00 00 00 0F 00 00 00 00
00 00 00 00 00 00 00 00 00 20 00 00 00 FE 00 41
55 4F 0A 20 20 20 20 20 20 20 20 20 00 00 00 FE
00 42 31 35 36 48 54 4E 30 33 2E 37 20 0A 00 95

And this is EDID on Mojave:

upupmings-iMac:~ upupming$ ioreg -l | grep "IODisplayEDID"

    | |   | | |       "IODisplayEDID" = <00ffffffffffff0006afed3700000000001701049522137802d1159e59539b271e505400000001010101010101010101010101010101783780b470382e406c30aa0058c1100000180000000f0000000000000000000000000020000000fe0041554f0a202020202020202020000000fe004231353648544e30332e37200a0095

// End

Looks like they are the same.(at least 20th byte & checksum are the same)

Sorry, I couldn't download Extron EDID manager because it's now verifying my sign up account yet.

From #54, I think there is nothing wrong with my EDID value, since we got same result on mac and Windows.
