    If you can't adjust brightness level on some Samsung netbooks (NC110, NC210 and some other-branded laptops) then open as root /etc/default/grub and change value of GRUB_CMDLINE_LINUX to "acpi_backlight=vendor". Don't forget to save the file :). Then open terminal, execute "sudo update-grub" and input your password. Reboot your PC after the updating is complete.

    Maybe I'm ressurecting old topic...but anyways....My HP500 laptop is too bright at night even on the lowest brightness setting, is there any software that will force the backlight go even dimmer?
