This tool allows you to control the way users log onto your machine.
Graphical interface: if you wish to see the X Window System (graphical display) started at boot time, check the Launch the graphical environment when your system starts box. If you leave it unchecked, the text login will be displayed.
Autologin: if you're the only person to use your machine and nobody else has access to it, you may choose to be automatically logged in at boot time. If this is what you want to do, check Yes, I want to autologin with this (user, desktop). Then choose the user who will be logged on automatically in the Default user pull-down menu, and the preferred Default desktop in the other pull-down menu.
