Thanks for the script. Getting the level is no problem, but turning down returned:

---
sg@sg-vaio:~$ ~/Desktop/Brightness_test.sh down
your current brightness level is : 21
Error org.freedesktop.Hal.Device.LaptopPanel.Invalid: /usr/lib/hal/scripts/hal-system-lcd-set-brightness: 29: arith: syntax error: "HAL_PROP_LAPTOP_PANEL_NUM_LEVELS - 1"
your new brighness level is :20

I also tried with sudo, I don't know if this it's necessary for that. The return is the same at all.
