Comment 17 for bug 317127

OK calibrate works with the cursor in current directory, but only the X axis (horizontal) portion is correct. The Y axis shows max as 6998 but doesnt get reset to the actual max which is displaying as 3939. Plus I think the min Y is also off... as a result tapping the pen anywhere on the screen and the X (horizontal) position is correct, but the Y (vertical) position of the cursor remains near the top third of the screen in a small margin...

Terminal from calibrate tool:
