Public bug reported:

I have a Lenovo ThinkPad Twist (convertible ultrabook with Core i7
processor) with touch screen, touch pad, rubber nipple mouse, and
external Bluetooth mouse. From these 4 mice 2 always work, the touch
screen and the external Bluetooth mouse.

The touchpad and the nipple do not work right after turning on the
machine, only when I reboot the machine they work after rebooting. I
have observed the problem only recently, so it is perhaps triggered by
the BIOS upgrade to version 1.57. The problem is independent of the
Ubuntu version. I did not only observe it on the installed Raring and
Saucy systems but also with several live CDs of older Ubuntu versions
(Quantal, Precise).

There is also another user with the same problem. See

http://www.iasptk.com/ubuntuwp/tag/13-10/

and search for "twist". Unfortunately, the question got removed from Ask
Ubuntu, but one can still access the dmesg output from this user on
