Hi,

Firstly, I would like to express my sincere gratitude for your repository. It has greatly saved me a significant amount of time.

I am using your configuration with my X1C7 FHD i5 8th version. The display seems to work fine. However, when I plug in an HDMI cable, the external monitor works fine, but the internal screen goes black. Even after removing the HDMI monitor, the internal screen still does not work.

Moreover, the internal screen sometimes goes black after the Apple Logo disappears during the booting process, but macOS is still up (keyboard caps lock and notification audio are working fine). I have to force restart or connect to an external monitor to restart my laptop.

I am a newbie, and after Googling a lot, I think the issue may be related to the device-layout-id or frame-buffer configuration.

Could you please help me solve these issues? Thank you.
