i3lock(1) User Manuals i3lock(1)NAMEi3lock - improved screen locker
SYNOPSISi3lock [-v] [-n] [-b] [-d] [-i image.png] [-c color] [-t] [-p pointer]
[-u] [-e] [-I] [-f]
DESCRIPTIONi3lock 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.
-d, --dpms
Enable turning off your screen using DPMS. Note that, when you
do not specify this option, DPMS will turn off your screen after
15 minutes of inactivity anyways (if you did not disable this in
your X server).
-I, --inactivity-timeout
Specifies the number of seconds i3lock will wait for another
password before turning off the monitors, in case you entered a
wrong password or canceled by pressing Escape. Only makes sense
together with -d. If omitted, the default is 30 seconds.
-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 Win‐
dows-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.
