Thanks a lot, it works. I have added to /etc/sudoers this

Code:

user ALL = NOPASSWD: /etc/powerlaunch/*

then created /etc/powerlaunch/kb_light

Code:

#!/bin/sh
b=/sys/class/leds/keyboard/brightness
lux=/sys/devices/platform/i2c_omap.2/i2c-0/0-0029/lux

on(){
echo >$b 10
}
off(){
echo >$b 0
}

maybe_on(){
if [ `cat $lux` -lt 5 ] ; then on ; else off ; fi
}

case $1 in
    on) on ;;
    off) off ;;
    *) maybe_on ;;
esac

and finally modified/added lines to n810.conf

Code:

keyboard_slide_open = if $islocked unlock_keys ; call keyboard_light_on
keyboard_slide_close = if $relock tklock.main.lock ; call keyboard_light_off
keyboard_light_on =  exec "sudo /etc/powerlaunch/kb_light"
keyboard_light_off =  exec "sudo /etc/powerlaunch/kb_light off"

and it turns keyboard light off when kb is closed and turns it on when opened in a dark. This is already enough for me but perhaps it also needs to be turned on/off when slide is open and screen is turned on/off. However, I am not sure how to do it.
