Dell Inspiron 7577 4K version. No screen output or no acceleration.

Hi, RehabMan and community. Maybe you have an idea how to enable iGPU but with 4K panel? I am either getting no acceleration with wrong platform_id or I see that video driver is started but I am stuck in that verbose screen. I can hear the sounds of OS when I press Enter in empty password field. Any help is appreciated.

Use -cdfon kernel flag (for WhateverGreen.kext).

Thank you so much! For some reason I could not find this information nowhere. You have helped a lot.

I don't know why you would need to manually add it though... all the plists from the guide have it already:
