Public bug reported:
Upon successful installation of Ubuntu 15.10, I ran the usual updates
and after restarting, the touchpad stopped working.
I booted into kernel version 4.2.0-16 instead of the updated kernel
4.2.0-34, and the touchpad that had stopped working functioned as usual
once more. Changing back into the latest kernel disabled the touchpad
once more.
I am installing Ubuntu on the Dell Chromebook 11 "Candy" running Intel
Celeron(R) CPU N2840 (Baytrail) processor. This deployment is being used
for several lab machines of the same model.
Steps to reproduce:
1. Install Ubuntu 15.10.
2. Run update.
Expected:
1. All hardware to work prior to update.
Instead:
1. Touchpad stopped working.
