Rotating the screen and swapping touchscreen orientation?

I have a Dell Latitude XT tablet that folds into a usually-portrait format.  xrandr -o yadda will rotate the screen just fine, but my touchscreen still keeps the normal orientation.  Is there a way I can configure or script this computer to rotate the touchscreen orientation while rotating the display?

Here's the lsusb section related to this touchscreen device.  It is a dual-mode touchscreen and stylus input device.

Bus 003 Device 002: ID 1b96:0001 N-Trig Duosense Transparent Electromagnetic Digitizer

Hello,

Sounds familiar to https://bbs.archlinux.org/viewtopic.php?id=106491

Please look at Xorg.log to determine which driver is used for your touchscreen.

Just looked into aur for the new synaptics multitouch support, and this scrolled by:

Re: Rotating the screen and swapping touchscreen orientation?

Thanks for the help!  After playing around a bit with xinput, I eventually just wrote a bash script to do this:

#!/bin/bash

rangex=( 0 9640 )
rangey=( 0 7220 )
torotate=( 9 10 )

xrandrout="$(xrandr)"

case $xrandrout in
 *800x1280* ) cal=( ${rangex[@]} ${rangey[@]} ); rotate=0;;
 *1280x800* ) cal=( ${rangey[@]} ${rangex[@]} ); rotate=1;;
esac

xrandr -o $(( rotate * 3 ))
for input in ${torotate[@]}; do
 xinput set-prop $input "Evdev Axes Swap" $rotate
 xinput set-prop $input "Evdev Axis Inversion" 0, $rotate
 xinput set-prop $input "Evdev Axis Calibration" ${cal[@]}
done
