[newbie] Cannot Log On to Mandrake 6.1!

[Jacob Voelcker]

I have just installed Linux Mandrake 6.1, and it won't accept my logon name
or password. I have tried the root name and password, and the unprivileged
username and password, but it won't accept either. So I reinstalled and
chose different logon names and passwords. However, it still won't let me
log-on. All I see is a text-based screen with a low-res picture of the Linux
penguin, my hardware details and a prompt line which says "localhost
logon:". Help!
