Hey guys. Sorry to revive a dead thread, but I have the exact same issue. Except my graphics is Intel HD3000.
I've opened up a thread myself. If you guys figured out any solutions please share!

Hello.

I have exactly the same issue with an HD 3000. I can use internal laptop display with -x option at bootup. With normal boot only external hdmi output is available.
Does anybody know how to fix this ?

Thanks.

This thing happened because your system cannot get correct EDID from your LCD pannel. You need to inject it other way.

For example I've got a Samsung NP530U3C-A0F - EDID: 

00 FF FF FF FF FF FF 00 4C A3 00 02 00 00 00 00 00 16 01 04 80 1D 10 78 2F 0C C5 96 5B 52 92 29 24 50 54 00 00 00 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 9E 1B 56 78 50 00 18 30 30 20 25 00 25 A5 10 00 00 19 00 00 00 FD 00 00 3C 30 D9 08 00 0A 20 20 20 20 20 20 00 00 00 FE 00 35 33 30 55 33 43 2D 41 30 46 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 1E

Injected with bootloader. Panel is working good.

 

In my case problem is in ig-platform-id. Have to use a 0x0166000A which make my display as an external and i cannot use brightness control. HDMI don't work on that id too.

On 0x01660003 I've got a some kind of overbrighted(sorry for bad bad english) display. HDMI works perfectly, no glitches at all. Brightness controll working.

Can't change anything at all by patching AppleIntelFramebufferCapri.kext
