I want to calibrate my desktop. I managed to find the colour option in the settings menu, but the calibrate button it's greyed. How to activate it so I can calibrate my colours?

I'm trying to calibrate my LG L1730SF USB touch screen with Ubuntu 14.04.
If I run the "calibrate touchscreen" application and follow the steps needed, it doesn't calibrate.
I also looked at this thread: cannot calibrate touchscreen , but no luck.
