Touchpad toggle works just fine on my T420s, that's what I used for
testing the upload. What desktop do you use?

  User reports:

  If you check /etc/acpi/events/lenovo-touchpad, it responds to the ACPI
  event of the Fn+F8 key by calling the script /etc/acpi/thinkpad-
  stretchortouchpad.sh, which in turns call /etc/acpi/asus-touchpad.sh,
  which is the file changed in this last update.

  In this new version, /etc/acpi/asus-touchpad.sh tests the output of
  'xinput list' against the string "PS/2 Elantech Touchpad", which
  doesn't match the actual device which is "SynPS/2 Synaptics TouchPad".
