I have upgraded from 16.04. to 16.10 on a ThinkPad X230.
Everything went well. I used the machine for a whilem then went into the BIOS and disabled the touchpad because I want to use the trackpoint only.
When I rebooted, I had no keyboard or mouse in Ubuntu. The keyboard works fine in the BIOS on in recovery (console). The keyboard, touchpad, trackpad work fine on other OSes or with a LiveUSB of 16.04 and 16.10. A USB mouse or keyboard won't work on my 16.10, but will work in other OSes or LiveUSB.
I don't know where to look anymore. I tried what this suggested: Ubuntu 16.04 freezes on login screen, no keyboard or mouse working but to no avail.
Where should I look to understand what's going on, and how to fix?
