Public bug reported:

Following the instructions @ https://wiki.ubuntu.com/DebuggingTouchpadDetection:
  Laptop model: Acer C710 Chromebook
  Manufacturer of the Touchpad: Cypress APA I2C Trackpad
  When the symptom first appeared: Never worked from clean install of Ubuntu 13.10 64-bit

Touchpad has not worked since clean install of Ubuntu 13.10 64-bit.
External mouse (Microsoft [I know, I'm sorry.] Arc Touch Mouse) works
fine. I'll attach `dmesg`, `/proc/bus/input/devices` and
`/var/log/Xorg.0.log` as according to the instructions.

Additionally, I've run `ubuntu-bug linux`, `/proc/version_signature`
says: "Ubuntu 3.11.0-12.19-generic 3.11.3", `lsb_release -rd` says:
"Description: Ubuntu 13.10, Release: 13.10" and I've attached `lspci
-vnvn.log`.

The Long Story
==============
I've used the Acer C710 Chromebook to run ChrUbuntu 12.04, upgraded through to 13.04 and very briefly 13.10. The Cypress APA Trackpad has been widely panned and in my personal experience, "barely works" is a kind way of describing this worthless hardware.

Today, I jumpered the hardware firmware write-protect described @
http://johnlewis.ie/pre-built-coreboot-firmware-for-chromebooks/,
flashed it with coreboot / seabios and performed a clean install of
Ubuntu 13.10 64-bit. That's when the trackpad went from "barely working"
to not being detected.

I appreciate anyone looking into this and just holler if I can provide
more information!
