[QCLUG] Root functions in Ubuntu

[Robert Jones]

I understand that Ubuntu / Kubuntu doesn't want you to log in as "Root". 
Sometimes I have a need to do things that require "Root" or 
"Administrator". An example is, in Kubuntu, I want to change my "image" 
at "System Settings > User Information > Password & User Account > Click 
To Change Your Image".  Sometimes I can change the image and sometimes I 
get the message "Your administrator has disallowed changing your image."

My question is; If I want to do something using a GUI that requires 
Administrator access, how do I do it? In this particular case I can't 
even change my image from a Root log in since it would change the image 
for the Root user. Is there some way to force Kubuntu to allow me to do 
things it requires the administrator permission to do?

Thanks for the help.
