Harris Anggara (harrisanggara), could you explain me with some detail what did you do to make this patch work?
What text did you add?changed?removed? in which file (I can't file any drivers/input/serio/i8042.c)?
And how can I know what I should replace X455LDB for?

Title:
  Elantech touchpad stops working after suspend

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  i have asus a455ld i5 5200u running kubuntu 15.04 with kernel 4.0.8-040008-generic. 
  touchpad is recognized as elantech version 4. everything was fine until my notebook go to suspend and resume without touchpad working.
  I tried :
  modprobe -r psmouse
  modprobe psmouse

  it only work before suspend.
  execute those commands after resume from suspend is not working.

  the last thing i tried is this.

  when i use this command before suspend :

  insmod
  /lib/modules/4.0.8-040008-generic/kernel/drivers/input/mouse/psmouse.ko

  these appear in the dmesg:

  [  820.207105] psmouse serio1: elantech: assuming hardware version 4 (with firmware version 0x381f00)
  [  820.222270] psmouse serio1: elantech: Synaptics capabilities query result 0x10, 0x14, 0x0e.
  [  820.294698] input: ETPS/2 Elantech Touchpad as /devices/platform/i8042/serio1/input/input146

  but when i use the command after suspend, there is nothing any output
  in the dmesg.

  i tried all ubuntu varian and opensuse 13.2 live usb, the result is the same. 
  but in windows 10,  touchpad still active after suspend.
