[Bug 1562155] Re: Touchpad stopped functioning after kernel update for Dell Chromebook "Candy"
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.5 kernel[0].
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.
If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".
Thanks in advance.

Title:
Touchpad stopped functioning after kernel update for Dell Chromebook
"Candy"
Status in linux package in Ubuntu:
Incomplete
Bug description:
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.
