[Bug 1248808] [NEW] volume and brightness keys are mismapped on Samsung Chromebook

[Hans-Christoph Steiner]

Public bug reported:

I've got XUbuntu/saucy on this US$250 Samsung Chromebook 5.  It runs
very well, it just had a couple of minor issues that need to be fixed
and it'll be an awesome little Ubuntu laptop with a regular Ubuntu
install!

The volume and brightness keys don't work.  When I checked them out
using xev, they were returning F keys:

F1 - back (i.e. like in a browser)
F2 - forward
F3 - refresh
F4 - fullscreen
F5 - switch screen mode
F6 - brightness down
F7 - brightness up
F8 - mute
F9 - volume down
F10 - volume up

I'm happy to try my hand at fixing it, but the documentation in
https://wiki.ubuntu.com/Hotkeys/Troubleshooting pointed towards a non-
existent file for directions on the next steps:
/usr/share/doc/udev/README.keymap.txt
