I am not recieving much, except for the error above in KDM. When I go to
runlevel 3 and try to login then it does not accept my login. It does not
even ask for my password.
I have a backup of yesterday of the /etc, however the shadow file is not in
it. Does anyone know why? It's a standard tar czf of the entire directory.
