I have a new X220 Tablet, and the Pen and Tablet functions work perfectly out of the box as long as the unit is on the Ultrabase. As soon as I remove from the Ultrabase (or boot while not connected), the Pen & Tablet functions stop working.
Conversely, if I dock the X220, the Pen & Tablet functions begin working again. The behavior is the same regardless of whether I have an external monitor attached or not.
