I have used "shutter" until now.
Now I found out that Mate include a own screenshot-utility aka mate-screenshot.
It works proper for me with just one problem:
Every time I pressed the "PRTSCR-Key" mate-screenshot starts interactive.
I did not want to install other screenshot tools.
So my question is: How to do to get mate-screenshot work in automatic save mode without open the GUI?
You can assign a keyboard shortcut to run this command : mate-screenshot
It will start without interactive mode.
You can also edit the .desktop file /usr/share/applications/mate-screenshot.desktop to edit the Exec=mate-screenshot --interactive into Exec=mate-screenshot and the regular app icon from the menu will run without interactive mode.
