[ltp] keyboard not working on Helix 2nd generation tablet with ThinkPad Helix Ultrabook Pro Keyboard

[John Reid]

No, I have not. I tried to find a live cd but could only find one for
Debian stable (7.8). However I don't think it would matter as I'm fairly
sure it is a problem with the kernel input drivers.

It looks like an event handler is created for the keyboard by
libevdev(?), but the hardware device driver (hid?) is not working.

I've created some (currently *very* rough) notes at
http://www.thinkwiki.org/wiki/Installing_Kubuntu_15.04_on_a_Thinkpad_Helix_2nd_generation

Cheers,
John
