Same problem with my Asus S56CA-XX030R ultrabook. The brightness decreases for
one single level, and remains unchanged on further tries. Fixed it by
installing xbacklight and using command :
xbackligh -set xx
where xx range from 00 to 100

keyboard doesn't actually affect screen brightness, and when it lowers
brightness due to inactivity the screen flashes scaringly. Same
