How to Disable touchpad while typing on Aspire One

I want to disable the touchpad while I type on my Aspire one netbook. If I issue the command syndaemon the synaptics driver is not detected:

Unable to find a synaptics device

So, I added the following to my xorg.conf file:

Section "InputDevice"
Identifier "Mouse0"
Driver "synaptics"
Option "Protocol" "auto"
Option "Device" "/dev/input/mouse0"
Option "ZAxisMapping" "4 5 6 7"
Option "CorePointer"
Option "HorizEdgeScroll" "1"
EndSection

It is still unable to find a synaptics device, however my touchpad works fine.

on my lap-top I just go to the System > Prefrences > Mouse and under the Touchpad tab make sure Disable touhpad while typing is checked... after that it automatically disable the touchpad whenever I am typing... pretty cool if you ask me...

You may try reverting the change you did (or keeping it) and installing the gpointing-device-settings package, which will provide more configuration options for your touchpad. Since Ubuntu 10.04 LTS this package replaces gsynaptics, if I remember well.

sudo apt-get install gpointing-device-settings

Once installed you can find it under System -> Preferences -> Pointing Devices.
