I just got a W540 today and found out the touchpad is different than the previous models. While the previous models have three actual keys (left, middle, right), the new model has no key and the whole touchpad is a button.
In the old models you can scroll a page but holding the middle button and move the trackpoint. Is it possible to do that on W540?
If not, is there anyway to enable "one-finger scrolling"? That is, I want the whole touchpad to be a scrolling pad... as long as I move finger there it will scrolls. Is that possible?
The system is Ubuntu 14.04.
