Can I bypass auto login and force login screen temporarily?
So here is the thing. I have a public computer used more or less as a public internet kiosk. As such I have enabled automatic login to the guest/kiosk account in case of a power failure or some other unforeseen problem that may force a reboot and no one is around with a password. I also have my personal account that I use as administrator to make sure everything is running well and up to date. Occasionally I have to reboot for an update or whatever and I was wondering if there was a way to override auto login and force the login screen to come up so I can choose my admin account rather than have it automatically login to the guest account where I have to ctrl>alt>del back to the login screen. Is there a keybinding I can use or set at boot to bypass the automatic login that one time? I do not want to disable auto login altogether as that would not be practical for this machine. It is more of an annoyance than a problem and I just wanted to know if this was possible and I was just ignorant to it and taking the long way around so to speak. I hope I have made myself clear what I am trying to do, if I can clarify in any way please let me know. Thanks
FYI: this is Ubuntu(Gnome) Hardy 8.04
