Bug Description
I don't know if this is really a kernel bug or if it's any other component, please help me know how I can diagnose the problem better.
This is a bug I have been experiencing with both 15.04 and 15.10, while this was not a problem with earlier distributions -- unfortunately, I don't remember which one in particular was actually working.
I have a Thinkpad Twist -- a hybrid laptop with touchscreen. The touchpad almost never works (even though sometimes, erratically, it does). The keyboard sometimes stops working, and works again after a suspend/resume cycle. Sometimes it behaves as if a key is stuck.
When running xinput --list, I don't see the touchpad. The touchscreen and external input devices connected via USB, however, work fine.
I was thinking this was a hardware problem, but on the same machine with Windows the problem does not appear to present itself.
