Reply with quote

I am installing gentoo to a cherrytrail tablet(pluto a108, I could not find much information on the internet), my current problem is that I have no backlight controls:

Code:

(none) ~ # ls /sys/class/backlight/
(none) ~ #

I have enabled all the backlight settings I could find in the kernel, here is my config:
https://p.defau.lt/?SV1fwTYoSsLyFWYoegUrTg

how do I find out which backlight driver I need?

thanks

Do you have the controls when you boot from a linux live USB?
