    brightness doen't change using fn+f5/fn+f6 on sony vaio [Solved]

    I just upgrade from karmic to lucid, but since then I can't use the fn keys to change brightness to my computer, it's a sony vaio VGN-NW170TJ.

    I only can change it by using the battery icon, but I want to use the fn keys...

    You can try this:

    Press Alt+F2 and type:
    Code:
    kdesudo kate /etc/default/grub
    Type in your password. The file will open in kate for editing 'as root.'

    Look for the line:
    GRUB_CMDLINE_LINUX=""
    Between the quotes ("") insert this:
    acpi_backlight=vendor
    so that the line looks like:
    GRUB_CMDLINE_LINUX="acpi_backlight=vendor"
    Save and close Kate.

    Open a console and type:
    Code:
    sudo update-grub
    Close the console, logout and reboot your PC.
