How to change touch screen functionality from a relative to an absolute pointing device?

Question

I'm using a Serial Wacom Tablet touch device on an HP EliteBook 2740p.

The capacitive finger touch device (Serial Wacom Tablet touch) works, but is set to relative positioning instead of absolute. This means it works like a touchpad rather than a touch screen. System Settings has options for the pen portion of the touch screen, but I can't find any settings for the touch part. Is there anyway to configure the touch screen to work as an absolute pointing device?

Thanks

This is the output of xinput:

This is the site of the wacom linux open source drivers:

The following page describes a set of commands that can change teh configuration of the tablet during runtime:

http://sourceforge.net/apps/mediawiki/linuxwacom/index.php?title=Tablet_Configuration

my guess is that the command you need is:

xsetwacom set "device name" Mode Absolute

where "device name" should be replaced by the name of the tablet, obtained by

xsetwacom --list devices

make sure you use the name that includes "touch" in it e.g. "Wacom BambooFun 2FG 4x5 Finger touch"

then the command would be

xsetwacom set "Wacom BambooFun 2FG 4x5 Finger touch" Mode Absolute
