Public bug reported:
Using the latest 16.04 LTS (Ubuntu 4.4.0-64.85-generic 4.4.44), my Dell
Inspiron 7548 wakes everytime the Elan touchpad registers a touch. This
causes the machine to wake when the lid is closed, and renders the
suspend/hibernate function useless.
The only way in which the suspend doesn't respond to the touchpad is if
the touchpad is manipulated *during* the suspend process.
This is true when removing the drivers or unbinding the hardware in
/etc/pm/sleep.d; removing or unbinding will still cause the laptop to
wake from sleep unless the touchpad has been touched between removing
the driver and suspending the laptop.
Disabling everything in /proc/acpi/wakeup has no effect on the issue.
