Brightness keys not working

[vicebtx]

Firstly.
THANKS a lot for this work. I spent more than 5 days with no avail trying to make Catalina run properly on this laptop until I found this repo!!!!
Congrats!!!

After installation, i had some issues with my trackpad not working (ELAN0626), i followed a link on a post in other issue raised here and fixed it with a couple of kext files and some .adl
Now i'm facing issues with the keys to control screen brightness, as they do not respond, i don't even see the option to lower the brightness manually in the display's configuration
The audio ones work flawlessly though.

Is there anything i'm missing??

My Laptop is the Lenovo L340-15irh.
Intel i7 9750H.
8GB RAM
GTX 1050.

I made it work. If anyone else is having the same issue, all I needed to do is to remove all "backlight" related kexts, updated Lilu.kext, WhateverGreen.kext and installed AppleALC.kext. Rebooted and got the backlight under "Displays" in sysconfig working. Fn keys are not responding to F11 and F12 but to Fn+K and Fn+P, but i can work with it.

Hope it helps.
