this is the standard behaviour of the X server. You'll need either a desktop
environment that maps the device to the screen or do it yourself with the
"Coordinate Transformation Matrix" (google has heaps of results, there is no
single authoritative source).

the xinput tool has a "map-to-output" argument which is sufficient in the
majority of cases.
