Feedback on the Lenovo ThinkPad X250

Unfortunately, the trackpoint points don't work under Ubuntu 14.04. Left and right buttons map to scrolling but not to the standard behavior you would expect. Forcing psmouse.conf to use imaps protocol and purging synaptics enables only the left trackpoint button but the right and middle buttons don't work. In addition no drag and drop or scrolling are possible. As it is right now the trackpoint buttons are useless... I am not sure why the x250 receives a certified status if the most basic input device does not work...
