[Sussex] The first of the Debian based confusion(s)

[John D.]

Well, as you'll all note from the title, I've obviously managed to get 
the knoppix installed to my HDD and have been digging round to try and 
get it so that it will become "proper" Debian.

So, having tried to follow the instructions that Thomas posted, I've 
tried to mod the apt-sources.list, without much luck.

I'm quite happy to dump the knoppix one, but what exactly do I need to 
replace the info with. The knoppix one reflects german located testing 
sources - which seem to be working fine(ish). I can't suss out whether I 
just need to show it something like this?

# Testing
deb http://ftp.de.debian.org/pub/debian testing main contrib non-free
deb http://ftp.de.debian.org/pub/debian-non-US testing/non-US main 
contrib non-free

# Testing Sources
#deb-src http://ftp.de.debian.org/pub/debian testing main contrib non-free
#deb-src http://ftp.de.debian.org/pub/debian-non-US testing/non-US main 
contrib non-free

or does it need to have a security source as well? or maybe is it just 
like the top part i.e. just a deb listing, or does it need a deb-src 
listing as well?

do I need to have something for stable, unstable and testing to get the 
testing? or just a testing listing ??

Erm yes, I'm a bit confused about that (gentoos portage was a little 
easier on the grey matter from that point of view)!

Could someone point me in the right direction please ???

p.s. Another anomally, is that "it" won't allow me to log in as root 
graphically - I can su and su- but not graphically. Any ideas why or 
where I'd look to change it ?
