I think the OP is seeing the console login screen *briefly* between the
end of the startup and the appearence of the GUI login screen.  He
probably has the (default) graphical startup (which shows a graphical
progress bar screen instead of the 'Starting foo    [OK]' lines on the
system console.  Once the startup finishes, the graphical progress bar
screen goes away, the console login screen shows up (briefly) and then
gdm starts the X server for its GUI login screen.

This is normal (for UNIX/Linux systems).  I know, it is not very
'Windowsy', which 'seamlessly' goes from its 'Windows is starting...'
to its GUI login screen.  This is due to these factors:

1) Even when you set the init level to 5, the console login screen(s) are
still available -- Ctrl-Alt-F1...F6 are available for console logins,
and Ctrl-Alt-F7 selects the GUI login screen.

2) The incarnation of the X server that is running during the graphical
startup is not continious with the incarnation of the X server that is
running (started by) gdm for GUI logins.

Note: unlike MS-Windows, the X server (the GUI subsystem) is a user-mode
process and is transient.  It is actually re-started when one logs out.
