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

Touch Pad not working on Shutdown, Works after Reboot Though
July 19, 2013Uncategoriz
I have a Thinkpad Twist and Ubuntu 13.10.
Whenever I restart my touch pad always works.
Whenever I shutdown, and turn it back on, the touchpad never works.
The touchscreen always works.
When it boots up the cursor shows for about a second in the center, then the cursor goes away (After a shutdown when the touchpad doesn't work). Logging out and back in doesn't fix it.
Here is a link to the output of dmesg when it doesn't work:
