It's called synclient. I've been fooling with it for years. The problem
is that it's got almost 100 parameters and not a very good explanation of
any of them. I tried setting something - probably in KDE that "turned off
the touchpad while typing". It lasted about 15 minutes. I go quickly
from typing to mouse functions and the imposed delay was worse than the
original problem. There's probably a way to fine tune it, but I don't
know what it is.
I currently have edge scrolling turned off and it does it anyway. My
touchpad is slightly left of center and my finger usually ends up at the
right edge. When I mouse over to the vertical scrollbar on the right
edge, my cursor almost always keeps going off screen and off the
scrollbar. And that's a minor problem! It's also fun when I mouse up to
the scroll up arrow at the top of the scrollbar and it keeps going until
it stops on the close window button....
