Title:
  AlpsPS/2 ALPS GlidePoint become less sensitive to single touch

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  The touchpad on this system was detected as a PS/2 mouse on 12.04.3
  Now it's correctly detected as AlpsPS/2 ALPS GlidePoint on Trusty dailylive (3.13.0-23)

  However, it become less sensitive to single touch detection
  I could genetly use my finger tip to control the cursor on 12.04.3, but now I have to incerase the contact area between my finger and the touchpad, which induced more firction.

  Another way to confirm this issue on Trusty with this system is:
  1. Do two-finger scrolling with finger tips (with small contact area of your fingers)
  2. After you can successfully scroll, remove one finger, you will find single touch does not work with a small contact area of your finger.
