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.
