Ubuntu – Synaptics Touchpad – cursor moves around when just ‘tapped’ after Ubuntu 12.04 upgrade

sensorssynapticstouchpad

After upgrading to version 12.04 LTS I experience some problems with my touchpad. Everytime I tap on the touch the cursor is moving around (for example if I want to close a window, I click on "x" button from touchpad, the cursor is moving and not always hit the "x" button). Touchpad left click, right click is working well, but tap… Did u guys experience the same problem? Is there something related to sensitivity? how to fix it?

Thanks

EDIT: Need help !!! It is really annoying

It seem to be just a synaptics driver configuration, I solved by adjusting the FingerLow and FingerHigh values with sinclient. See your current configuration with synclient, here is my console output

$ synclient | grep FingerHigh
    FingerHigh               = 30
$ synclient | grep FingerLow
    FingerLow               = 25

I change the FingerLow value to 35, and FingerHigh value tu 40 and it works better! Try:

$ synclient FingerHigh=40
$ synclient FingerLow=35

The values were determined experimentally. To make the configuration permanent I created the file /etc/X11/xorg.conf with the following content

Section "InputClass"
    Identifier "touchpad"
    Driver "synaptics"
    MatchIsTouchpad "on"
    Option "FingerHigh" "40"
    Option "FingerLow" "35"
EndSection

Regards!
