Hijacking this thread - apologies.

Pet peeve: why are so many people insistent on BREAKING the very security 
mechanisms that have been built into Ubuntu?!  You told a self-confessed 
noob, to break the config to a non-standard Ubuntu setup!

If people absolutely MUST have a root shell, use "sudo bash" or "sudo -s -H".  
Personally I don't see the big deal of either of those sudo incarnations 
versus "su -".  We're talking a handful of keystrokes here which, if it 
really bugs you, can be added as a shell alias anyway :) eg,
alias r="sudo -s -H"

Put that in ~/.bash_profile then all you need to get a root shell is to type 
"r" (as in "r"oot).  Enter your user password and voila!  I've even hacked 
by .bashrc so that my normal user account has a different prompt to my root 
shell:
if [ `echo $UID` -eq 0 ]; then
    PS1="\n\[\033[1;31m\]\u@\h - \[\033[1;32m\]\w\n\[\033[0;37m\]>"
else
    PS1="\n\[\033[1;36m\]\u@\h - \[\033[1;32m\]\w\n\[\033[0;37m\]>"
fi

That's a colour prompt (red=root, cyan=my normal user account), and not 
everyone's preferred "style" but have a play :)  My point is, that I can 
separate my normal user account and root shells so that it mimics the 
behaviour of a traditional *nix "root-enabled" setup without sacrificing the 
Ubuntu-way.

OK, I'm off my soap-box now.  Flame away :)
