Title:
AlpsPS/2 ALPS GlidePoint vertical pointer speed is very low

Status in libinput package in Ubuntu:
Incomplete
Status in linux package in Ubuntu:
Incomplete

Bug description:
While moving pointer (cursor) using Touchpad, vertical movement is
very slow and short (= less velocity and less acceleration compared to
horizontal axis). Horizontal movement is fine. So, when circle is
drawn on the Touchpad, the pointer moves in oval shape.
