    If you never change your laptop's brightness than that means you are shortening the time you have available when away from AC power. The screen is the biggest power drain.

    root@panagiotis-laptop:/home/flamelab# sh /etc/acpi/video_brightnessup.sh
    grep: /proc/acpi/video/VGA/LCD/brightness: No such file or directory

    There is a workaround in 7.10: just adapting the script manually.

    another workaround is using the gnome panel brightness applet.

    just add it to your panel and use the mouse wheel to make it go up or down, works great.
    When close to achieving you quit! If you don't try you failed. Real Winners are not afraid of losing.
