Yeah, I tried that, but I always end up with this same problem. When I tried 
setting a root password before (because it always seemed like the *right* 
answer), I got this same result. 

When I made the move from Kubuntu to Debian, I went through this root-password 
thing at least 5 or 6 times. I always ended up with a system where I could 
not be granted admin or root privileges ... EXCEPT in a sudo su shell! So 
that's what I usually do: I create a sudo su shell, then exit and allow 
permissions to expire, then when I need quick access again, I just hit my UP 
arrow key, re-enter password, and go back into sudo su to kill something or 
whatever else needs immediate attention. 

Now, it would be nice to crack this nut, once and for all, but I don't want to 
keep asking my own machine for permission to do things. The question is, 
which of us is master?

Will check it out, thanks.

I am always prepared for some black magic. That is why I keep my *Linux in a 
Nutshell* grimoire always close to hand. Oh, and salt, burning sulfur, 
candles and incense, and some cats. 

I used to keep goats and chickens, but nowadays my landlord is always 

Seriously, whatever you can recommend to get me back "in control" of the 
Mother Ship. 

Thanks a bunch!

It sounds like these kids forget everything about security, privacy, whenever 
somebody says the word "cloud" -- then it's all okay.
