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

[Guest]

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:

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:

sudo update-grub

Close the console, logout and reboot your PC.
