Public bug reported:

Setup:
Ubuntu 14.04.1LTS
IIyama 19" Pro-Lite Touchscreen
Dell 17" regular monitor

Due to another bug in the detection of input devices I had to write a
script to tell Ubuntu which screen to use the touch from the
touchscreen.

so I put the following two entries into a basic bash script based on xinput list and xrandr -q 
========
#!/bin/bash
xinput map-to-output 12 DVI-I-1
xrandr --output DVI-I-1 --primary
=========

I added this script to /usr/share/lightdm/lightdm.conf.d/50-dualscreen-touch.conf
and the contents look like this.
============
[SeatDefaults]
greeter-setup-script=/usr/local/bin/iiyama-touchscreen.sh
session-setup-script=/usr/local/bin/iiyama-touchscreen.sh
============
When I start a user session the touchscreen is calibrated and works normally with the touch happening on the touchscreen.
As soon as I logoff into LightDM the touch calibration is off moving the pointer a logarithmic distance from the left of the touchscreen. 

As soon as I log in again, no problems, touch works great, log back out
into the lightDM greeter and boom touch is all crazy.

Can lightdm please detect that a touchscreen can only accept touch input and output to the touchscreen device??
Or at least have lightdm actually run the script when given?
