Changing brightness is not working with FN keys on Lenovo Yoga S740. I don’t know if it’s hardware related or not. The ls /sys/class/backlight
command gives the following output intel_backlight
. Since FN+11 and FN+F12 keys have functionalities in the system, I assume changing brightness should work with F11 and F12 keys.
are you using a DE or wm like i3? you can try to give a command in the terminal to check which if brightness works. For example
xbacklight +10
perhaps sudo pacman -S xorg-xbacklight
might be worth a shot
I’m using Gnome,. It would be awesome the brightness would work from the keyboard
i would bet it is somehow hardware related on this devices ?

Since I got output after running ls /sys/class/backlight
it might not be hardware related, but you might be right.
