Actually, the recommended command to start gnome that was suggested (and
I am using) is:
exec ck-launch-session dbus-launch --exit-with-session gnome-session

I know that dbus-launch has been the "proper" way to start it for a
while. I don't know that it will affect startup, but it should make for
a cleaner shutdown if I understand what it does.
