[Bug 1357208] [NEW] laptop touchpad not working upon kernel upgrade

 

Public bug reported:

My laptop model: HP Spectre 13t-h200 x2 PC
manufacturer of touchpad: I believe Synaptics. Supposed to have multi-touch (this works in Windows).
Symptom appeared: every time I booted into the listed newer kernel version, as well as the ones after (or at least the newest one).

When I was using kernel version 3.13.0-30-generic, the touchpad was able
to move the mouse. It could not do a two-finger scroll and I would like
to file this as a bug too, but I don't know where to file it (can you
give advice?). However this is not the current issue.

After upgrading to version 3.13.0-32-generic, the touchpad is no longer
able to move the mouse. I have attached the `dmesg` output and the
contents of '/proc/bus/input/devices' and /var/log/Xorg.0.log after
booting into each kernel.

** Affects: linux (Ubuntu)
     Importance: Undecided
         Status: New

** Attachment added: "the files I said I would attach, for each kernel version"
