It is possible for laptops even circa 2004 to enjoy the two-finger scroll functionality of the more modern apple macbooks.

To enable this feature, you must edit your xorg.conf file

locate the module section and add a line to load the synaptics driver if it is not already there.

Section "Module"

   Load   "synaptics"


Then locate your TouchPad entry (i.e.  Section "InputDevice") and add the following parameters:

Option   "VertTwoFingerScroll"   "1"
Option   "HorizTwoFingerScroll"   "1"

Restart your services and you will now enjoy horizontal and vertical two-finger scrolling on your linux laptop!
