How to make Shutter as the default screenshot tool?

We need to install CompizConfig Settings Manager (CCSM) to bind Print and Alt + Print to Shutter. Follow these steps:

Install compizconfig-settings-manager .

Open Dash (press Super) and query for ccsm and hit Enter to run CompizConfig Settings Manager.



Under the General Category, you would find the option called Gnome Compatibility. Click on it (not the Checkbox beside it, ie; keep the checkmark activated).
