x-terminal-su

A button for launching an X terminal as a superuser

A shortcut for 'sudo -s'

... for 'gksu' nostalgics ...

Install

Copy 'x-terminal-su.desktop' in '/usr/local/share/applications/'

Copy 'x-terminal-su.png' in '/usr/local/share/icons/'

Usage

Look at menus of your graphical desktop environment (Mate, Gnome, Xfce, KDE ...)
Now you see a new button 'Terminal for Super-User' sides to others buttons launching terminal emulators.
This new one does the same, with a 'sudo -s'

Tips

To avoid sudo asking for password each time, you can edit '/etc/sudoers.d/sudoers.local' and add a line with 'Defaults timestamp_type=global'

Note that this may impact security considerations. Read the manpages of sudoers.
