ohhh and that tapping on the mouse pad.....doesn't work? or is there a setting so I could close a window by just "tapping" or double click something by jsut tapping?
No, you really cant.... unless you decide to manually edit the Xorg and X11 config files which I strongly recommend you not to!
The two finger click works well for me!
P.S.: In Mac world, its known as the "trackpad"
