You may be running a server that also has X Windows loaded for administration purposes. You could hose your X Windows configuration and need to have a text-based log in just to repair the setup. There are a number of reasons this could be necessary. You may be wondering why would anyone use a text-based log in when simple, user-friendly graphical logins are available. You can also pass on to X that you are starting a multi-headed session (more than one monitor) with this command: startx – -layout Multihead.
