Increasing the value increases the acceleration when moving the cursor
(which is not quite the same as increasing cursor "sensitivity". BTW,
after a little practice, I reduced the AccelFactor to 0.1. There are
many other options one can add and/or modify in /etc/X11/xorg.conf. As
stated, this was just a "quick fix" which got the touchpad to a usable
state. It's still not perfect, but before, it was unusable. Experiment!
