Can't see the User on the login screen My user name does not appear on the login screen. There are two users and only one is shown. 

Is there any way to see the other user or some user name input box instead of selection?
Try this:

Press the Down arrow on the keyboard to highlight any user (make sure the password entry box is NOT open.)

Press Option + Return on the keyboard.

This should bring up the username and password fields on the login screen.
