The systemd script is running nevertheless finger touch input is still recognised while the digitiser is active. Finger input then takes precedence of the digitiser (you can notice a jumping mouse courser).

simon@laptop:~$ systemctl | grep wacom
wacom-proximity@simon.service                                                             loaded active     running      [ThinkPad Yoga] Wacom digitizer proximity detection
system-wacom\x2dproximity.slice                                                           loaded active     active       system-wacom\x2dproximity.slice

Runnig the script from command line I recognise following error message:

simon@laptop:~$ /opt/thinkpad-yoga-scripts/wacom/thinkpad-yoga-prox.sh 
unable to find device ELAN Touchscreen

xinput does only know following devices:

simon@laptop:~$ xinput --list

As described above the touch screen is working. Anything else I can do to debug the issue?

With the help of http://ubuntuforums.org/showthread.php?t=2270774 I found out that the touch screen now is called SYNAPTICS Synaptics Touch Digitizer V04. I thus changed the script accordingly and it now works.
I'm not sure what the best way is to provide a generic solution. I would be happy if you could add the support for the other touch screen.
