Using Wacom Cintiq 15x in ubuntu 12.04 for some reason if screen is rotated, twinview (separate x instances for each screen) will not work. when using 2 screens and no twinview, xinput_calibrator will not work correctly identify the device id: xinput –list | grep stylus identify the property to set: xinput list-props $id | grep Wacom\ Tablet\ Area to rotate: xinput list-props $id | grep Rotation for a rotation to the left set rotation to 2 calibrating with rotation 2: xinput -set-prop id prop y-top x-right y-bottom x-left

• lower numbers for x move to left
• lower numbers for y move down 
• example xinput -set-prop 10 273 60 -1475 6496 16000
