down and what what it was opening up.

bash: /etc/dbus-1/event.d/25NetworkManager: No such file or directory

See above. :-(

I had finally successfully purged network-manager and network-manager-kde.  
Now I can't get on line to reinstall them.  Not by any means.  And they 
aren't on the install CD I used, anyhow according to apt.

Now  I'm really in a mess.  I would reinstall teh whole thing from scratch, 
but that would scrap the Japanese and I still wouldn't be online.
