Elantech touchpad cannot be toggled

Bug Description

There is no support for disabling an Elantech touchpad.

There is the script /etc/acpi/asus-touchpad.sh, which should probably be called synaptics-touchpad.sh, because it only toggles synaptics touchpads. There should be an equivalent script for Elantech touchpads.

I will attach some relevant info - output from xinput list, xinput list-props, and a candidate script modeled after asus-touchpad.sh.

Hi James,

Instead of creating a separate script for this, could you please add support for the Elantech touchpads to the asus-touchpad.sh script? That way we future-proof against doing stupid shell tricks in the event that some future ASUS or Lenovo model uses these touchpads.

Also, do you have a new /etc/acpi/events/ rule to go with this?

Attached is an alternate script for asus-touchpad.sh which handles both Synaptics or Elantech.

The following is also an events file contents needed for some more recent Lenovo Thinkpads (not just those with Elantech touchpads):

event=ibm/hotkey HKEY 00000080 000060a

  * asus-touchpad.sh: add support for Elantech touchpads. LP: #953296.
  * events/lenovo-touchpad2: new event handler for an acpi event on newer
    ThinkPads which always maps to the touchpad.

  [ Troy Sankey ]
  * asus-keyboard-backlight.sh, events/asus-keyboard-backlight-{up,down}:
    add support for hotkey that adjusts the keyboard backlight on the ASUS
    G73jh and others. LP: #931614.
