Adjust Sensitive Area of Synaptics Touchpad - Karmic Koala Ubuntu 9.10

Sometimes you may want to adjust the sensitive area (or other settings) of your touchpad. To do so type "synclient -l" in a terminal and you will get a list of options. At the bottom you should see AreaLeftEdge AreaRightEdge AreaTopEdge AreaBottomEdge which are probably set to 0. If you change these to a nonzero value the you it will define the edge of the touchpad. Use your LeftEdge RightEdge TopEdge BottomEdge values as references because they are close to the edge of your touchpad.
After you determine the values you need then you can put them in your HAL configuration file:
/etc/hal/fdi/policy$ cat 11-x11-synaptics.fdi
