I have updated my firmware, that doesn't change anything wrt this
touchpad bug.

$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Reading the diff, between the identified changes i'm sure that we will
bisect down to the patches that refactor and change things in the
synaptics driver.

Title:
  ideapad yoga needs psmouse reload

Status in linux package in Ubuntu:
  Triaged

Bug description:
  So, my often made fun of, lenovo ideapad yoga, since sometime in the
  14.10 development cycle needs an extra help to get the trackpad
  working.

  On boot the mouse pointer is not visible.

  If I open terminal and do "rmmod psmouse; modprobe psmouse" the
  pointer magically appears on first touch.

  Please help me as to how I can bisect / track down what the issue here
  is. Sometime in the past it was working reliably.
