i'm hoping somebody could help me. I was trying to turn on my backlight laptop keyboard on lenovo T450s ubuntu 16 LTS, i had googling with nothings found,i tried FN+space and xset led 3.. please Help, Open source Teams
I got this from wuxmedia in another post for a t520,but it also works for my t450. Enjoy!
