I can't adjust screen

I can't adjust screen brightness on my Dell Mini 12 after editing /etc/default/grub and running 'sudo update-grub'.

$ sudo update-grub
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.32-22-generic
Found initrd image: /boot/initrd.img-2.6.32-22-generic

Found initrd image: /boot/initrd.img-2.6.32-21-generic
Found memtest86+ image: /boot/memtest86+.bin
done

My /etc/default/grub is:

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nolapic acpi_backlight=vendor"
GRUB_CMDLINE_LINUX=""

I really appreciate it if you give me some advice.

Thank you.
