[Bug 1504445] Re: FocalTech touchpad stops working after suspend

 

I forgot to say that to identify your laptop model you can run
sudo dmidecode | grep Product\ Name

you'll need to change 
DMI_MATCH(DMI_PRODUCT_NAME, "X455LAB"),
by
DMI_MATCH(DMI_PRODUCT_NAME, "XXXXX"),

XXXXX being your laptop model

Title:
   FocalTech touchpad stops working after suspend

Status in linux package in Ubuntu:
  Triaged

Bug description:
  I have an Asus V502LX the persian version of the Asus K501LX.

  I have Ubuntu 14.04 installed and the kernel 4.1.6 installed. I had to
  install the kernel 4.1.6 to have the touchpad recognised. Under kernel
  3.19.30, as I am running now to file in this bug, the touchpad is
  recognised as a simple mouse (no two fingers scrolling...) and the
  problem I am describing below is also present...

  I noticed one problem. The Focaltech touchpad is not working after
  suspending the computer.

  Here is what I could find about the touchpad in
  /proc/bus/input/devices

  I: Bus=0011 Vendor=0002 Product=0012 Version=0000
  N: Name="FocalTechPS/2 FocalTech FocalTech Touchpad"
  P: Phys=isa0060/serio1/input0
  S: Sysfs=/devices/platform/i8042/serio1/input/input5
  U: Uniq=
  H: Handlers=mouse0 event4
  B: PROP=5
  B: EV=b
  B: KEY=e520 10000 0 0 0 0
  B: ABS=260800000000003

  Before suspending the computer, I can deactivate and activate again
  the touchpad with the hotkey of my keyboard without problem. However,
  once the computer suspended, nothing work to re-activate the touchpad.

  I tried a solution given on internet but it doesn't work properly.

  I created a file here /etc/pm/sleep.d/0000trackpad
  sudo gedit /etc/pm/sleep.d/0000trackpad

  and add the following
  #!/bin/sh
  case "$1" in
      suspend|hibernate)
          modprobe -r psmouse;
      resume|thaw)
          modprobe psmouse;
  esac

  With this file, the computer refuse to suspend. The touchpad keep
  working so it does something but I can't make my computer sleeping...
