Screen rotates but touchscreen does not!

Hello everybody, I've got an interresting puzzle: I've set up a Thinkpad X220 Tablet with OpenSUSE 13.2 and TDE 14.0.1; Everything works wellincluding the Wacom digitizer, I've been able to install Open Sankore and MihPhoto from respectively a deb and an rpm package. TDE 14.0.1 on OpenSUSE seems to have a problem with this machine as it does not see my USB key as removable, but a workaround was setting a mount point in fstab. The puzzle is this: TDE proposes a system tray applet named "Resize and Rotate". It works like a charm, wich is usefull because the X220t's battery is a little bulky and lifts the back of the computer This is good in Notebook mode, but in Tablet mode, with the screen _physicaly_ rotated 180°, it's the front that is higher that the back. So if I rotate the screen _per software_ 180° everything is fine... However, the digitizer does not get the information, so the pointer appears on the wrong side of the screen - this is funny for 30 seconds but unusable after that. So, does anyone have an idea how to also rotate the touchscreen digitizer 180°? This does work in Windows 10, but I'd prefer to use Linux :) Have a nice evening, Thierry
