Hi, Todd,

My test steps are:
screen points
0 1
2 3

step 1. Calibration on (0 0 0 0) or just click blank area to create a junk config and save and restart X.
           This uses to simulate users who made mistake when calibration.
step 2. Did calibration (0 1 2 3) to correct the touch screen settings
           At this time, as your description about calibration algorithm, the calibration algorithm add rotation of counter clockwise and I have no way to change the settings to normal behavior.
step 3. Based on Todd's digging about the calibration algorithm, I do calibration again with counter order (3 2 1 0).
           This time, touch screen settings recover as normal behavior.

The reason I re-open this bug because I expect when finish step 2, use should get correct touch screen behavior as they want.
no user can understand the tricks in step 3.

BTW: I change the importance from "high" to "medium" because we have workaround (step 3) to help user to recover from misuse of calibration.

Thanks,
Lei Y
