Oh, sorry, I missed out an important step, my $HOME/backlight directory is a link to /sys/class/backlight/intel_backlight. You should either do the same or change $BACKLIGHT_DIR to the same thing, and then the brightness should get updated instantly when you run the script (no need for calling any xserver commands)
