Title:
  Touchpad no longer working on Asus Zenbook UX305FA

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have Ubuntu 15.10 installed, and all was working fine. Then I
  accepted some software updates and my mouse pointer no longer appears.
  If I plug in an external USB mouse then all is fine, but I want to use
  the touchpad - it was working, doesn't now.

  cat /proc/bus/input/devices gives me output that includes ...

  I: Bus=0011 Vendor=0002 Product=000e Version=0000
  N: Name="ETPS/2 Elantech Touchpad"
  P: Phys=isa0060/serio4/input0
  S: Sysfs=/devices/platform/i8042/serio4/input/input12
  U: Uniq=
  H: Handlers=mouse0 event5 
  B: PROP=5
  B: EV=b
  B: KEY=e420 10000 0 0 0 0
  B: ABS=661800011000003

  I did find a couple of bug reports for the UX305CA and tried
  installing the following debs downloaded from
  http://www.godisbeautiful.net/4.4rc8deb/, but it didn't fix the
  problem

  linux-firmware-image-4.4.0-rc8-touchpad_4.4.0-rc8-touchpad-1_amd64.deb
  linux-headers-4.4.0-rc8-touchpad_4.4.0-rc8-touchpad-1_amd64.deb
  linux-image-4.4.0-rc8-touchpad_4.4.0-rc8-touchpad-1_amd64.deb
  linux-image-4.4.0-rc8-touchpad-dbg_4.4.0-rc8-touchpad-1_amd64.deb
  linux-libc-dev_4.4.0-rc8-touchpad-1_amd64.deb

  Booting the previous versions of the kernel didn't help. I also tried
  editing /etc/default/grub to change this line ...

  GRUB_CMDLINE_LINUX_DEFAULT="i8042.reset quiet splash"

  ... and then ran update-grub and reboot, but it didn't make any
  difference.

  Help?
