Just to preface:
I've seen many resolutions to this problem, tried them all and every time I reboot. Screen turns a weird gray instantly at boot.
I have a 7inch raspberry pi touchscreen with a raspberry pi 4 4gb and a neego case and kali pi 2020.4. I have to rotate screen 180 degrees due to case.

I've tried the whole editing boot/config.txt
And adding lcd_rotate=2, still grey screen. Anyone know any solution to this issue would be greatly appreciated
