Pointer capture for touchpads?

[Richard Zidlicky]

Hi,

I have a simple proof of concept script for controlling the Sentelic touchpad, attached it 
if it is usefull to someone.

In principle it allows me to turn on/off the whole device or particular features
such as vertical/horizontal scroll or tap-click - and thus making the device much 
more tolerable.

It has somewhat nasty preconditions: requires either root privs for the scroll/click control
or Xserver access for enabling/disabling :( So I am not sure how it could be intergated into 
the desktop.

Another interesting thing I found is "evdaemon" - http://codegrove.org/evdaemon/, did
not try it yet but looks like it could do everything what syndaemon can do and a few other 
interesting things without beeing limitted to any particular device.
