Default Re: Brightness control not working with nVidia driver

Brightness control works for me with 169.07 and .04 on Gutsy.
I believe i had to modify acpi scripts in order for brightness control to work.
In /etc/acpi/ my thinkpad-brightness-down.sh is:
Code:
#!/bin/bash
manufacturer=`dmidecode --string system-manufacturer`
case "$manufacturer" in
    LENOVO*)
        echo down > /proc/acpi/ibm/brightness
        exit
    ;;
    *)
        . /usr/share/acpi-support/key-constants
        acpi_fakekey $KEY_BRIGHTNESSDOWN
    ;;
esac
and thinkpad-brightness-up.sh is the same as above with "up" instead of "down"
