Ubuntu – How to calibrate a touchscreen on a dual monitor system


I have a dual monitor setup of two different sizes. My primary monitor is a 23 in widescreen Acer T230H touchscreen, and the second is a regular 20 in. When I go to use the touchscreen, the cursor shows up on the secondary display depending on where I touch the display.
How do I calibrate it to only control my primary monitor?
