Built in keyboard won't work - Acer Chromebook R11 Ubuntu 16.10

Question

I'm trying to run Ubuntu 16.10 on a flash drive (not Crouton) on an Acer Chromebook R11. The built in keyboard won't work, but a USB keyboard does. I ran sudo apt-get dist-upgrade, that didn't change anything.

Any log files I could check to see what's happening? Is it possible to fix this?

Output of lsusb and xinput:

Answer 1

After skimming this discussion, it is my understanding that the keyboard works with linux kernel 4.7 but not 4.8.

I am now using the latest GalliumOS baytrail nightly and the keyboard works fine.
