This could be a hardware issue with the touchpad due to the fact a
previous kernel that once worked no longer works.
It might be worth trying a LiveCD from one of the prior releases to see
if the issue still happens.

Title:
Lenovo ThinkPad E460 20EUS00000 Touchpad not detected
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hi all,
for about one week now I cannot use the Touchpad of my ThinkPad
because Ubuntu does not detect it. I encountered the same problem
during the installation, but a few days later everything suddenly
worked. This time a miraculous fix has not happened.
The Touchpad stopped being detected from one day to another. Changing
back to an older kernel version (which worked completely fine before)
did not solve the problem.
I started having the problem with kernel 4.4.0-36-generic and tried
4.2.0-42-generic which did not help.
I will shortly add the desired logs and attachments. The Ubuntu
version I am using is Ubuntu 14.04.5 LTS.
Thanks in advance,
Stephan
