NAME

       i3lock - improved screen locker

SYNOPSIS

       i3lock [-v] [-n] [-b] [-i image.png] [-c color] [-t] [-p pointer] [-u] [-e] [-f]

DESCRIPTION

       i3lock  is  a  simple  screen  locker  like slock. After starting it, you will see a white
       screen (you can configure the color/an image). You can return to your screen  by  entering
       your password.

IMPROVEMENTS

       · i3lock forks, so you can combine it with an alias to suspend to RAM (run "i3lock && echo
         mem > /sys/power/state" to get a locked  screen  after  waking  up  your  computer  from
         suspend to RAM)

       · You  can  specify either a background color or a PNG image which will be displayed while
         your screen is locked.

       · You can specify whether i3lock should bell upon a wrong password.

       · i3lock uses PAM and therefore is compatible with LDAP, etc.

OPTIONS

       -v, --version
              Display the version of your i3lock

       -n, --nofork
              Don't fork after starting.

       -b, --beep
              Enable beeping. Be sure to not do this when you are about to  annoy  other  people,
              like when opening your laptop in a boring lecture.

       -u, --no-unlock-indicator
              Disable the unlock indicator. i3lock will by default show an unlock indicator after
              pressing keys. This will give feedback for every keypress and it will show you  the
              current  PAM state (whether your password is currently being verified or whether it
              is wrong).

       -i path, --image=path
              Display the given PNG image instead of a blank screen.

       -c rrggbb, --color=rrggbb
              Turn the screen into the given color instead of  white.  Color  must  be  given  in
              3-byte format: rrggbb (i.e. ff0000 is red).

       -t, --tiling
              If  an  image  is  specified  (via -i) it will display the image tiled all over the
              screen (if it is a multi-monitor setup, the image is visible on all screens).

       -p win|default, --pointer=win|default
              If you specify "default", i3lock does not hide your mouse pointer. If  you  specify
              "win",  i3lock displays a hardcoded Windows-Pointer (thus enabling you to mess with
              your friends by using a screenshot of a Windows desktop as a locking-screen).

       -e, --ignore-empty-password
              When an empty password is provided by the user, do not validate  it.  Without  this
              option,  the  empty password will be provided to PAM and, if invalid, the user will
              have to wait a  few  seconds  before  another  try.  This  can  be  useful  if  the
              XF86ScreenSaver key is used to put a laptop to sleep and bounce on resume or if you
              happen to wake up your computer with the enter key.

       -f, --show-failed-attempts
              Show the number of failed attempts, if any.

       --debug
              Enables  debug  logging.   Note,  that  this  will  log  the  password   used   for
              authentication to stdout.

DPMS

       The  -d  (--dpms) option was removed from i3lock in version 2.8. There were plenty of use-
       cases that were not properly addressed, and plenty of bugs surrounding that feature. While
       features  are  not  normally  removed  from  i3 and its tools, we felt the need to make an
       exception in this case.

       Users who wish to explicitly enable DPMS only when  their  screen  is  locked  can  use  a
       wrapper script around i3lock like the following:

            #!/bin/sh
            revert() {
              xset dpms 0 0 0
            }
            trap revert HUP INT TERM
            xset +dpms dpms 5 5 5
            i3lock -n
            revert

       The -I (--inactivity-timeout=seconds) was removed because it only makes sense with DPMS.
