No, I havn't looked in /var/log/messages. I am not sure if this is a bug. I havn't updated my system and reported this.
After I restarted the os, it becomes workable.

vlock-main
VLOCK-MAIN(8) Linux Programmer's Manual VLOCK-MAIN(8)
NAME
vlock-main - lock current virtual console
SYNOPSIS
vlock-main [plugins...]
DESCRIPTION
vlock-main is part of vlock(1), the Virtual Console locking program for Linux. It locks the current session and will only exit if the cur-
rent user can authenticate themselves. The root user will also be able to unlock the session, unless disabled at compile time. The com-
mand line arguments specify plugins that should be loaded by vlock-main. See vlock-plugins(5) for more information.
If plugin support is disabled at compile time, the only supported argument is "all".
ENVIRONMENT VARIABLES
The following environment variables can be used to change the behavior of vlock-main:
USER
If this variable is when vlock-main is run as root (uid 0) vlock locks the screen as this user instead of root. The root password
will still be able to unlock the session, unless disabled at compile time.
VLOCK_ALL_MESSAGE
If this variable is set and all consoles are locked its contents will be used as the locking message instead of the default message.
VLOCK_CURRENT_MESSAGE
If this variable is set and only the current consoles is locked its contents will be used as the locking message instead of the
default message.
VLOCK_MESSAGE
If this variable is set its contents will be used as the locking message instead of the default. This overrides the former two
variables.
VLOCK_TIMEOUT
Set this variable to specify the timeout (in seconds) after which the screen saver plugins (if any) will be invoked. If this vari-
able is unset or set to an invalid value or 0 no timeout is used. See vlock-plugins(5) for more information about plugins.
VLOCK_PROMPT_TIMEOUT
Set this variable to specify the amount of time (in seconds) you will have to enter your password at the password prompt. If this
variable is unset or set to an invalid value or 0 no timeout is used. Warning: If this value is too low, you may not be able to
unlock your session.
SIGNALS
Several signals are ignored. vlock-main will try to exit cleanly if SIGTERM is received.
