trackpad script not working on startup / login

The issue at hand

My aim is to enable natural scrolling on system start (or session start), which - up until now - could be easily achieved using a startup script, but since migrating from 12.04 (32 bit) to 13.04 (64 bit) I'm not able to automate this task.

Here's the script used:

#!/bin/sh

xinput set-prop 12 273 -25 -25

it works when running independently, so it seem to be overridden by a later call. How to resolve this?

What have I tried?

Adding an entry in the Startup Applications for the trackpad script

Using a @reboot flagged entry in crontab to call the xinput command

Calling the trackpad script in .bash_login, or in .profile

Adding a .conf file in /etc/init

I think at some point I even tried to mess around with sequencing directories and sequencing file names under /etc/rc*

Including a call in various scripts under /etc/pm (that actually got things working for the boot phase, but any subsequent suspend/sleep would deactivate the trackpad custom settings, again).

Environment

Dell XPS 13, Ubuntu 13.04 64 bit.

This doesn't explain why it is happening, it's just a workaround.

You could automatically reset the property whenever it changes. Use this script:

#!/bin/bash

while true; do

  xinput list-props 12 | grep -q "Synaptics Scrolling Distance (273):.*-25, -25" || xinput set-prop 12 273 -25 -25

  sleep 5

done
