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
