Whenever I lock the screen on my USB Ubuntu install be it manually or automatically when I get back it just shows the desktop again without asking for a password.

How can I enable the password lock again? This way it's quite useless.

Thanks for your time.

do you have automatic login enabled (not on the screensaver/lock, i mean when the system first boots up)? – quack quixote Apr 22 '10 at 9:30

@Quack: I have disabled the autologin, and have a password set on my own account @Richard: Will take a look – Not Available Apr 22 '10 at 12:20
Just checked, have gnome-screensaver running, and I don't want to switch as it should work just fine, trying to figure out what's wrong. – Not Available Apr 22 '10 at 12:22
i wrote up this answer for a guy looking for passwordless logins on ubuntu. if i were you i'd check PAM settings for sanity. same guy asked another question in which i did some digging around on how the screensaver lock works -- that stuff about DBus didn't end up helping him but maybe it'll point you in the right direction. – quack quixote Apr 22 '10 at 12:43

I guess this is just a bug in the usb version of ubuntu, finally have a laptop so no need for ubuntu usb installs.
