  Binary package hint: xserver-xorg-input-synaptics
  
  When using tap-to-click, the synaptics driver fails to register some
  taps as clicks. I have managed to link this with abnormal coordinates
  reported by the driver using "synclient -m 10". Whenever a tap is not
  registered as a click, there is one or more consecutive reports of
  touching at coordinates (x=1, y=5855), which might explain why it is not
  registered as a click.
  
- I have recorded a few taps and saved them as a .txt file, which you can view at: http://ubuntuforums.org/showpost.php?p=3202355&postcount=5

+ pattern, when taps are registered and when they're not. I have found
+ that every time a tap is not registered there is a weird "1" appearing
+ on the X column and a "5855" on the Y column, meaning that my touchpad
+ registered touch at the (1,5855) coordinates. This, coupled with the
+ MaxTapMove=220 (default), means that it will register a movement during
+ my tap and as such it will invalidate it as a tap.
