  'SynPS/2 Synaptics TouchPad' doesn't work 'Lenovo Thinkpad T440p'
  after the kernel upgrade

Status in linux package in Ubuntu:

Bug description:
  Hi all,

  I have been using Xubuntu 16.04 since June 2016 on my Lenovo Thinkpad T440p 
(i5-4210M, 16GB RAM, NVIDIA 730M). However since last year (probably after a 
kernel upgrade), my touchpad has stopped working (I always keep the system 
upgraded via apt update/upgrade. It doesn't work at all, and I have to use an 
external mouse. As per the description at 
  Only very rarely, it somehow works as well (by rare I mean twice in the last 
two years), but as soon as I reboot, the state is back to non-working at all. 

  I attach an archive touchpad_debug.tar.gz containing two sub-folders
  working_state and nonworking_state. Each folder contains the dmesg
  output, my /proc/bus/input/devices, and my /var/log/Xorg.0.log when
  the touchpad was working and not working. In working_state, I
  additionally have the outputs to "xmodmap -pp", "xinput --list ", and
  "xinput --list-props <id>".
