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 current user can
authenticate themselves. The root user will also be able to unlock the
session, unless disabled at compile time. The command 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 variable
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.
