A temporary fix has been reported by Hans and i am attaching his comment
on the other thread. Thanks a lot Hans. I hope we can fix this bug
permanently soon.

Hi,

Fixing this is non trivial, supporting these new touchpads likely needs
a signicant amount of work (for details see
https://bugzilla.redhat.com/show_bug.cgi?id=1110011 ).

In the mean time, I can provide a workaround which should make the
touchpad work in ps/2 mouse emulation mode (so no 2 finger scrolling,
etc.), and stop it from interfering with an external mouse.

Sounds good? Try booting with "psmouse.proto=bare" on the kernel
cmdline.

See: https://wiki.ubuntu.com/Kernel/KernelBootParameters for how to add
a parameter to the kernel commandline.

Regards,

Hans

Title:
  [Asus X550LD] Touchpad and Mouse Pointer not working properly

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  The touchpad is irresponsive but sometimes just throuws the pointer to
  some edge of sceen if you try to move it. There is no clicking action
  either.

  I am using a usb mouse and it performs as expected ususally. In some
  ocassions the pointer's clicking functionality seems to get stuck at
  some window feature like ( menu bar, content space, some button,
  titile bar etc) . It moves properly but the clicking action is
  performed only in that region and nowhere else on scree. Once that
  area is clicked/right clikd again, it goes back to normal functioning.
  In a few ocassions when I could not detect where it is stuck I had to
  reboot the system and then it worked fine. I have notices that this
  problem generally starts  if I have suspended the system.

  I have tried updating the BIOS to the latest version but it did ot
  have any different effect.

  xinput list output , I have the usb mouse connected:
