I have been using GDM on my workstation at work (rather than just booting into text mode). I don't use Gnome, though - just Windowmaker. Is there a way to (automatically and / or manually) lock the screen besides using "gdmflexiserver"? I think that's more intended for starting a second session than locking the existing session. I'd like something like what xscreensaver does, only with the gdm login screen. Also, is there a way to set a default username BUT prompt for a password? The only option I see in the config file is to automatically log in as a particular user. w
