[tlug] [Newbie] Becoming 'root' in Kubuntu

[CL <az.4tlug@example.com>]

It sounded so simple ...

I need to edit a couple of script files for Kubuntu and need to be root 
to do so.  Kate doesn't have an Admin level and it is too difficult to 
figure out the editing commands in Konsole, assuming there are any.

If I have understood the instructions correctly, all that is required is 
to enable the root account in System Settings -> User Management and to 
set the password.  Did that, assigning 'root" the Primary User Group of 
'root' but cannot login.  Do I need to assign 'root' to 'admin'?  I'm 
lost ...

And, why does Kubuntu switch to German when you log out and try to log 
back in again?  It is a language I read / speak, but why the change? 
BTW, when I try to log back in as root, the error message is "Anmeldung 
des Beneutzers root ist nicht zuelassig" (the "ue" should be an " 'u' 
mit umlaut, but I am not configured for German input here) which makes 
me think I am doing something wrong at a very basic level.
