Public bug reported:
Brand new ThinkPad Helix with docking keyboard (part number 20CGCTO1WW)
Keyboard works fine in Windows and in Grub, but is not detected whatsoever in
Ubuntu. (I've also tried Ubuntu MATE and Mint with the same result.)
I did find /dev/input/by-path/platform-i8042-serio-0-event-kbd which
looks like it might be the correct device. It is a link to
/dev/input/event3. Running an "hd" and an "evtest" on that device yields
no results, while it does give results for a USB keyboard.
