PC-BSD® uses the GNOME Display Manager () as its graphical login program. This program was chosen for its support of keyboard layouts, localizations, and accessibility.
A GDM Configuration utility is available in Control Panel. Figure 8.5a shows the initial screen when you click on this icon in Control Panel or type pc-su pc-gdmconf at the command line. Note that this utility will prompt you for your password.
The "Remote login" tab, shown in Figure 8.5b, is used to configure, a protocol that comes with Xorg and allows a connection to an X session from a remote system. Uncheck the "Enable XDMCP" box to enable this service and expose the configuration options. By default, XDMCP uses UDP port 177, allows one connection per host, and allows up to 16 simultaneous sessions.
For security reasons, no connections are allowed by default. If you check the "Allow incoming TCP X connections", other computers in your network may have access to your GUI. Use extreme caution when enabling this option as it can make your system available to anyone over the network. If you are enabling this option for troubleshooting purposes, uncheck this box immediately after finishing your troubleshooting session.
