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".
