It is not possible to run GDM, but it is possible to run gnome-shell,
gnome-session, gnome-keyring in JHBuild without the help from a display
manager. JHBuild gnome-session is the primary desktop environment on my
FreeBSD desktop machine because packages provided by FreeBSD tend to be
out of date. Features requiring GDM or polkit don't work in JHBuild, but
I don't really care them because they are not essential for basic
functionality of desktop.

Here are my steps to run GNOME session on X11 on FreeBSD.

1. Login from a text console. I usually use VT 2 to avoid seeing
messages from the kernel and daemons. It is also possible to login from
ssh, but it seems the a local session works better with ConsoleKit.

2. Run 'screen' so we can see messages sent to stdout and stderr without
switching VT. We can re-attach the screen session from gnome-terminal.

3. Run 'screen Xorg'. It will be started on VT 9 on FreeBSD.

4. Run 'screen jhbuild run env DISPLAY=:0 gnome-session'. It will prompt
for gnome-keyring password because we don't use a display manager.

It is also possible to run JHBuild GNOME session on a remote server with
TigerVNC. 'jhbuild run gnome-session' usually works for me.
