Status in linux package in Ubuntu:
  New

Bug description:
  CID: 201307-13943, 201307-13944 Lenovo B490s

  The hotkey (Fn+F6) for disabling / enabling touchpad does not work on
  this system.

  
  In xev, only the Fn key press could be detected (keycode 151), combined with F6, nothing shows up execpt keycode 151
  ubuntu@201307-13944:~$ xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p'
  keycode 36 = (keysym 0xff0d, Return), state = 0x0
  keycode 151 = (keysym 0x1008ff2b, XF86WakeUp), state = 0x0
  keycode 151 = (keysym 0x1008ff2b, XF86WakeUp), state = 0x0
  keycode 151 = (keysym 0x1008ff2b, XF86WakeUp), state = 0x0
  keycode 151 = (keysym 0x1008ff2b, XF86WakeUp), state = 0x0
  keycode 151 = (keysym 0x1008ff2b, XF86WakeUp), state = 0x0

  Fn+F6 could be detected by acpi_listen
