Tap-to-click is disabled on the XO, as far as I am aware there are no events visible to user software when the pad is touched. The hardware supports this though, and if you run other Linux on the XO it does tap-to-click. <blockquote type="cite">Do you think would like it best if the ripple occurred on touchdown or liftoff...or both? </blockquote> Touchdown only. <blockquote type="cite">In my mind's eye, I imagine the surface tension letting go and causing a ripple as I lift my finger off the pad. Of course, it could ripple on landing, too. However, I was wondering about what *minimal* effects would be *just enough* rather than making lots of ripples during frequent pad strokes when I am most likely to be aware of the cursor's location. </blockquote> Yep, this would take a lot of fine tuning to not be annoying. One could experiment with this by just using move events - if the pointer was not moved for some time, and then is moved, that could trigger the effect. - Bert - </div></blockquote></body></html>
