Title:
  2 levels of brightness change on single key press

Status in “gnome-settings-daemon” package in Ubuntu:
  Confirmed

Bug description:
  On my Asus laptop K53U,  /usr/lib/gnome-settings-daemon/gsd-backlight-
  helper adjusts /sys/class/backlight/acpi_video0 when receiving
  KEY_BRIGHTNESS-UP/-DOWN while the BIOS in fact adjusts the brightness
  itself on the key pressed too.

  This causes two levels of backlight brightness change on one key press.
