Brightness is very low when boot and suddenly become normal after 5 mins

[smallbearayu]

Hello guys,

Recently I installed mojave b4 on my laptop because it supports 8th Intel CPU and IGPU officially. Most of functions work fine and the UHD 630 IGPU works nicely except for a very weird bug.

When booting into the macos, the internal screen is very very dim (just like setting the brightness to minimum) and after about 3-5 mins the screen suddenly become normal.

Has anyone also experienced this problem? Is there any solution to it?

Thanks a lot.

Attached is my debug file in case someone needs it.

missing FakeSMC.kext in /Library/Extensions

all kexts needs to be installed to /Library/Extensions

InjectKexts should be set to Detect in config.plist

Keep in mind you may need to determine what PWMMax is used by the CFL framebuffer kext and adjust LMAX as appropriate.
