I've got the same problem with at least 13.04 and now with 13.10. I've noticed, that the gnome-screensaver deamon wasn't running after a fresh login. Once the deamon is running, locking after suspend is working again.
I didn't figure out, why this deamon isn't running. However my simple workaround: just add the gnome-screensaver to the session startup list (gnome-session-properties). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1083030 Title: Ubuntu >= 12.04 resumes from Suspend without password prompt To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1083030/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
