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  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.
