Version 18.04.3 right mouse key stopped working, I attempted to try and make the right key the primary key settings, devices. Now neither key works, if I left click on an icon in the favorites column a box appears with : new window, open a new window, remove from favorites and show details.
So currently there is no way to use the mouse. However if I left click on the desk top I can get to the terminal.
My question is:
Is there a way from the terminal to reset the the mouse settings to their original state?
