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,
