[Touch] No touch works at all

[Krzysztof]

Right after installing 14.04 finger touch worked all right with Chromium (Wacom touchscreen): I could at least scroll pages and go back/forward. However, at some point, after one of updates, it stopped. I have no idea how it was before, but following code added to the /usr/bin/chromium-browser brings touch back:

finger_id=$(xinput list | grep "Finger touch")
if [ ${#finger_id} != 0 ]; then
  finger_id=${finger_id#*id=}
  finger_id=$(expr match "$finger_id" '\([0-9]*\).*')
  CHROMIUM_FLAGS="$CHROMIUM_FLAGS --touch-devices=$finger_id"
fi

I'm not professional in coding, so this may be clumsy, but perhaps a better version of the above can be added when the script is updated.

Attached, a patched version of the script.
