Tried that on my T440p. It sorta works. Unfortunately clicking makes the pointer move, so I end up clicking the wrong thing. All. The. Time. It's comically bad.

I ran into the same thing with a T440 we got for a customer, but he didn't care because he just carries a wireless mouse from exam room to exam room with it.

Made working on it a bit surreal recently though until I figured out that he'd stuck the mouse in his pocket and was walking by in the hallway.

Ubuntu synaptic drivers got it right. You dont have to push the touchpad all the way. Only touch it with two or three fingers.

Hmm, it doesn't move at all for me. (I'm on Windows using the default driver.)

I'm using Windows too. I tried playing with the settings and using default or various drivers. Accurately getting right vs left click is nearly impossible (takes 3 tried on average to right click) -- I simply don't use it as a laptop.
