I can't change the brightness on my laptop

xbacklight -dec 40 doesn't work
echo 5 > /sys/class/backlight/acpi_video0/brightness doesn't work either

I'm using bumblebee (not that i think that matters)
I have intel hd graphics and a nvidia geoforce 610m

in /sys/class/backlight there are 3 directories acpi_video0 acpi_video1 and intel_backlight
