Hi all,
I have a Huawei Matebook X Pro(UHD 620) and I patched graphics but the computer screen doesn't work...
The display is 3000x2000 so technically QHD, but the thing is, I can't change the DVMT value in BIOS because it's apparently rewrite proof (even EFI shell doesn't work)... So right now I'm just assuming that the DVMT is enough.
The computer boots with an external display connected VIA HDMI (USB C), and the screen stays black with the backlight on. Then the external display stops working within a minute, so I have to sleep the computer and wake it up for the external display to remain on, the backlight turns off.
Main problem:
- internal display will work without acceleration, external display will not work
- internal display will not work with acceleration (framebuffer patches), external display will work
- with acceleration config.pllst, and without the external monitor plugged in, boot will be stuck in verbose (IOcounsel...)
- can't modify DVMT values in bios (rewrite protected)
What I think:
If the DVMT isn't the issue, then I think it's the EDID that's causing the trouble. I will upload the EDID file.
On a side note, can anyone link a guide to create a new layout ID for appleHDA, this laptop has 4 speakers but non of the defalt layouts will work.
Thanks!
