[ubuntu] Trackpad dies when suspending

Hello,

First of all I hope I'm in the right place.
My problem is that when I suspend my computer (with Ubuntu 16.04), my trackpad disappears and I have to reboot to get it back. This is very aoying as suspending happens when I close the lid.

To illustrate the problem I found that I could get some informations about the touchpad with these commands :

Code:

$ egrep -i 'synap|alps|etps' /proc/bus/input/devices
$ xinput list "$(egrep -i 'synap|alps|etps' /proc/bus/input/devices |cut -d'"' -f2)"

When doing this before suspending I get, respectively :

Code:

N: Name="ETPS/2 Elantech Touchpad"

and

Code:

ETPS/2 Elantech Touchpad                    id=12    [slave  pointer  (2)]

This looks normal, but when I try that after suspension , they give not result at all...
After some researches I found a solution implying a /etc/pm/sleep.d/0000trackpad script but it was on a much older thread (ubuntu 13) and did not help me at all.

Any help would be very appreciated and I'd like to thank those who will look into this in advance
