Title:
  [Lenovo IdeaPad Y500] Brightness keys not working

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Although the brightness keys and brightness indicator behaviour seems
  normal, the actual brightness of the monitor does not change.

  I've tried different solutions as the following  without luck:

  Changing grub to:
  GRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=vendor" followed by a grub update

  And changing xorg.conf adding to the Device section:
  Option "RegistryDwords" "EnableBrightnessControl=1"
