the ubuntu way of managing passwordless users is not through the use of empty passwords (which are dangerous as they will also allow free access to the machine services like ssh for that account), but using locked passwords (which will look like the account is disabled in gnome users settings) but enabling them to login without a password through gdm by adding them to the nopasswdlogin group (the don't ask for password on login checkbox) when adding a user and then managed that as an exception through pam.
sadly the same problem described here would happen to those since gnome- screensaver is unaware of that special group and the "workaround" is to click on swich to another account and then selecting your own account to get out of the lock -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/674563 Title: Passwordless users are prompted for their password when the screen locks -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
