Hi, after some days of testing, it seems that my touchpad is finally working fine :) .

I've added other options to the configuration file above:

Option "FingerLoW" "35"
Option "HorizHysteresis" "50"
Option "VertHysteresis" "50"

You can set the "FingerHigh" option too.

You can't reload the touchpad module (as I wrote in the previous message, my mistake), but you have to restart X or reboot your computer.
