Touchpad for scrolling only

On ThinkPad Edge 325 laptop I have UltraNav device (both touchpad and trackpoint). I never use touchpad as pointing device, but I find it handy to use it for scrolling. Is there any way to disable all pointing device functionality on touchpad, but retain scrolling?

I read synaptics(4) manual and ThinkWiki articles for touchpad, trackpoint and UltraNav, but I see no solution there. Search on forum revealed a topic from 2012, but no solution there either.

Edit: I actually want to have only two-finger scrolling, so that all the events with one finger would be ignored by touchpad. The solution below indeed turns touchpad to scrolling-only device, but it still makes me suffer from accidential touchs.

Re: Touchpad for scrolling only

You could expand the right side scrolling area to your whole touchpad with the parameters synclient offers you.

Re: Touchpad for scrolling only

I ahve never tried this, but what if you made the actual requirements for pointer movement ridiculously small.  So much so that it would never register as being legit.  I'm not sure exactly what options you would use... maybe zpressure?  I have thought about this before, but the best thing that I could come up with was expanding the right scroll as mentioned above.

Of course, you could always just modify the source and recompile.
