Yep, that's what I would prefer, but so far...

So

- rotating screen and touchscreen (inside TDE) works well with xrandr and 
xsetwacom (thank you E.Liddell) .

- for "normal" landscape and "inverted" landscape it's possible to calibrate 
the touchscreen with xinput_calibrator

This addresses 90% of my needs so that's obviouly already a good thing. I 
wrote a tcl/tk front end so that I don't have to type the xrandr and 
xsetwacom commands.

If I want to use the screen in portrait mode, the pointer is somewhat offset, 
which is a problem if I am to try and write on a PDF. However, 
xinput_calibrator can't be used in this situation as it ignores portrait mode 
(or I don't know how to doit).

THe gnome calibration tool can be called with gnome-control-center wacom but 
it then gets no screen information and thus can't do anything.

If you know a way to run a full gnome-control-center from inside TDE, I'm 
interrested :)
