Hi all,
I've started a page at
http://www.thinkwiki.org/wiki/Installing_Kubuntu_15.04_on_a_Thinkpad_Helix_2nd_generation
that includes error messages and what I've been able to determine of the
bus layout.
At the moment I suspect the HID rdesc for the keyboard might be broken.
Still investigating, but I'm no kernel guru and last time I looked at
any C code was 20+ years ago, so it's a slow process.
So far I haven't had any feedback from Lenovo technical support. What is
the best way to contact them?
Cheers,
John
