[wellylug] Log in as root with Mnd 10 GUI

[Colin Iles]

Hi folks

I have the official version of Mnd 10 installed and really like it. 
However, I seem to be the only user listed for login.  I want to be able
to log in as root with a GUI interface (red) but cannot find how to set
this up. I can of course login as root with su in a terminal window, but
want also the opportunity to login via the GUI where I am currently the
only user shown.

Mnd 9.* set this up at install

Can anyone suggest how to do this please?
