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

 

With kernel 3.19 the touchpad is not recognized. That can be fixed by installing the Focaltech driver from my ppa.
It will not work if you installed another Elantech driver.  

So this is not a bug report, but a support request.

In kernel 4.2 (Ubuntu 15.10) the touchpad is recognized out of the box.

Title:
   FocalTech touchpad stops working after suspend

Status in linux package in Ubuntu:
  Incomplete

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...
