I've got a USB mouse attached to my Ubuntu notebook. This mouse is (unfortunately) really sensitive, and so it sometimes gets hard to hit small icons with the mouse pointer. This is really a hardware issue, it's not a bug and it's not Ubuntu's/gnome's fault. Still, I would very much like to this issue through software (solving through hardware would imply buying a new mouse).

Back in Windows, if I set the sensitivity as really low it was comfortable enough. In Ubuntu, even the lowest sensitivity and acceleration available (in the System>Prerences>Mouse menu) is still frustrating. How can I decrease it below the default minimum?

I tried xset, but it seems xset only deals with acceleration and threshold, but not actual sensitivity.
