(Sorry for the inconvenience)
PC-BSD uses the GNOME Display Manager (GDM) as its graphical login program. This program was chosen as it supports keyboard layouts, localizations, and accessibility.
Beginning with PC-BSD 9.1, a GDM Configuration utility is available in Control Panel. Figure 8.3a shows the initial screen when you click on this icon in Control Panel. Note that this utility will prompt you for the administrative password.

For security reasons, PC-BSD defaults to a login screen. This means that users are required to input their password before logging into the PC-BSD system. If you are the only user on the PC-BSD computer, always use the same window manager, and don't consider it a security risk for the system to automatically boot into that window manager, you can enable auto-login using the Auto login tab.
As seen in the example in Figure 8.3a, the "Enable auto login" box is unchecked by default. If you check the box, the "Auto login user" drop-down menu will be activated. Select the user account that you wish to automatically login as. You can also set a delay period (in seconds) ??
The Remote login tab, shown in Figure 8.3b, is used to configure XDMCP, a protocol that comes with Xorg and allows a connection to an X session from a remote system.
NOTE: use extreme caution when enabling this option as it can make your system available to anyone over the network. If you need someone to access your PC-BSD system to assist with troubleshooting, consider using Desktop Sharing instead, which allows you to send an invitation to connect. Always disable any type of remote login immediately after finishing your troubleshooting system.
