I'm using Ubuntu Mate 16.04 with ThinkPad T450s.
When I login into Ubuntu, keyboard back-light is on, then I turn it off, then after spending idle time when I touch to any key, keyboard back-light turn on again!
What should I do for disable it?
I found the
keyboard-backlight brightness file path that toggles with three mode:
1is low light
2is high light
I set the brightness to
rc.local as following, but it not worked:
I put the following line before
exit 0 in
echo 0 > /sys/class/leds/tpacpi:\:\kbd_backlight/brightness
Thanks in advance.
