Touchscreen Calibration
Assuming you have installed and run xinput_calibrator, now you need to map the input to output for your dual monitors. This is not a calibration, that part is done. This step tells the desktop's graphical interface what input ID goes to what output. Open a command prompt and type xinput. The list of input devices shown will show the ID unique to each device. Record the ID for each monitor. Now run the command :
____ xinput --map-to-output device_ID connection
____ xinput --map-to-output device_ID connection
