I have the same problem. My gnome "System" menu only has a "Quit" option, and it drops me directly to gdm. from gdm I have all of the usual options. I have beryl installed but its not running. I use the latest nvidia drivers so no Xgl. and my gdm config is the same as the original poster. I've had this issue since shortly after installing Edgy. and it persisted through a dist-upgrade to Feisty. Nobody has been able to offer any help on it, and its a real pain because this is a laptop and I'd like to work on getting suspend/resume working, but its useless if I have to log out to do it. if I can offer any help in troubleshooting this I'd be glad to do whatever i can.
