        You can maybe try to connect with a "normal user" and then
    swith to first console and take a look at /var/log to see any error
    (ie ls -ltr /var/log and cat the last modified file).
    By the Way I don't use GDM or KDM but XDM, so you should
    take a look at the {g,k}dm.log if it exist.
