Asus laptops are able to turn both the display and keyboard backlit off
by pressing a dedicated "turn display off" key (usually fn+f6). However,
on Linux systems, this key has no effect at all since most desktop
environments don't deal with KEY_DISPLAY_OFF. By mapping that key to
KEY_SCREENLOCK instead, would enable it to work as close as intended by
the manufacturer, since desktop envirorments would handle this as a
screen lock request by the user, locking the screen (and turning both
the display and keyboard backlit off on environments that support it).
