Henrik and Rafi,

I've tried to use this script with the Lenovo T410s, and it fails. It
seems that the following N-trig device returns two integers instead of
the expected one integer:

  /sys/class/input/event10/device/capabilities/abs

cat'ing it gives the following:

  730100 3

I haven't discovered any other irrgularities, but there may be some. Do
you guys know why this is? What it signifies? How to update the script
to account for it?

Here's some more info:

  $ cat /sys/class/input/event10/device/name
  N-Trig MultiTouch
  $ cat /sys/class/input/event10/device/phys
  usb-0000:00:1d.0-1.8/input1

Thanks,

d
