.IR image.png \|]
.RB [\|\-c

.SH DESCRIPTION
.B i3lock\-color
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.

.SH FEATURES
.IP \[bu] 2
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)
.IP \[bu]
You can specify either a background color or a PNG image which will be displayed
while your screen is locked.
.IP \[bu]
You can specify whether i3lock should bell upon a wrong password.
.IP \[bu]
i3lock uses PAM and therefore is compatible with LDAP, etc.

.SH OPTIONS
.TP
.B \-v, \-\-version
Display the version of your
.B i3lock

.TP
.B \-n, \-\-nofork
Don't fork after starting.

.TP
.B \-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.

.TP
.B \-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).

.TP
.BI \-i\  path \fR,\ \fB\-\-image= path
Display the given PNG image instead of a blank screen.

.TP
.BI \fB\-\-raw= format
Read the image given by \-\-image as a raw image instead of PNG. The argument is
the image's format as <width>x<height>:<pixfmt>.
The supported pixel formats are:
\'native', 'rgb', 'xrgb', 'rgbx', 'bgr', 'xbgr', and 'bgrx'.
The "native" pixel format expects a pixel as a 32-bit (4-byte) integer in
the machine's native endianness, with the upper 8 bits unused.
Red, green and blue are stored in the remaining bits, in that order.

.BR Example:
.Vb 6
\&	--raw=1920x1080:rgb
.Ve
You can use ImageMagick’s
.IR convert(1)
program to feed raw images into i3lock:

.Vb 6
\&	convert wallpaper.jpg RGB:- | i3lock --raw 3840x2160:rgb --image /dev/stdin
.Ve
This allows you to load a variety of image formats without i3lock having to
support each one explicitly.
You can also use it to resize images to the screen ratio:

.Vb 6
\&	convert wallpaper.jpg -resize $(xdpyinfo | grep dimensions | sed -r 's/^[^0-9]*([0-9]+x[0-9]+).*$/\1/') RGB:- | i3lock --raw $(xdpyinfo | grep dimensions | sed -r 's/^[^0-9]*([0-9]+x[0-9]+).*$/\1/'):rgb --image /dev/stdin
.Ve
Note that $(xdpyinfo | grep dimensions | sed -r 's/^[^0-9]*([0-9]+x[0-9]+).*$/\1/')
gets you the current screen dimensions in the wxh (e.g. 1920x1080) format.

.TP
.BI \-c\  rrggbbaa \fR,\ \fB\-\-color= rrggbbaa
Turn the screen into the given color instead of white. Color must be given in
4-byte format: rrggbbaa (i.e. ff0000ff is opaque red).
Use the last byte for alpha. Setting this below FF (i.e. ff000088) will allow
your screen to be shown translucently if you use a compositor (e.g. compton,
xcompmgr).

.TP
.B \-t, \-\-tiling
If an image is specified (via \-i) it will display the image tiled all over the
screen.

Note: For all image options, with a multi-monitor setup, the image is visible on
all screens.

.TP
.B \-C, \-\-centered
If an image is specified (via \-i) it will display the image centered on the
screen.

.TP
.B \-F, \-\-fill
If an image is specified (via \-i) it will scale the image until it fills the
screen. A portion of the image will be cropped.

.TP
.B \-M, \-\-max
If an image is specified (via \-i) it will scale the image until either the
width or the height fits the screen without being cropped. The border color
can be set via \-c.

.TP
.B \-L, \-\-scale
If an image is specified (via \-i) it will stretch the image until both the
width and the height fits the screen.

.TP
.BI \-p\  win|default \fR,\ \fB\-\-pointer= win|default
If you specify "default",
.B i3lock
does not hide your mouse pointer. If you specify "win",
.B 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).

.TP
.B \-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.

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

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

.SH i3lock-color OPTIONS
.TP
.B \-S number, \-\-screen=number
Specifies which display to draw the unlock indicator and clock on. By default,
they'll be placed on every screen.
Note that this number is zero indexed. The ordering is dependent on libxinerama.

.TP
.B \-B sigma, \-\-blur=sigma
Captures the screen and blurs it using the given sigma (radius).
Images may still be overlaid over the blurred screenshot.
As an alternative to this option, you could specify a translucent background
color (-c option) with a fully transparent or translucent color, and use a
compositor to perform blurring (e.g. compton, picom).

.TP
.B \-k, \-\-clock, \-\-force\-clock
Displays the clock. \-\-force\-clock also displays the clock when there's
indicator text (useful for when the clock is not positioned with the indicator).

.TP
.B \-\-indicator
Forces the indicator to always be visible, instead of only showing on activity.

.TP
.B \-\-radius
The radius of the circle. Defaults to 90.

.TP
.B \-\-ring\-width
The width of the ring unlock indicator. Defaults to 7.0.

.TP
.B \-\-{inside, ring}\-color=rrggbbaa
Sets the idle color for the interior circle and ring.  Note: use individual
options per element unless the shell supports brace expansion (in which case
remove the spaces inside the curly braces).

.TP
.B \-\-{inside, ring}ver\-color=rrggbbaa
Sets the interior circle and ring color while the password is being verified.

.TP
.B \-\-{inside, ring}wrong\-color=rrggbbaa
Sets the interior circle and ring color for during incorrect password flashes.

.TP
.B \-\-line\-color=rrggbbaa
Sets the color for the line separating the inside circle and the outer ring.

.TP
.B \-\-line\-uses\-{inside, ring}
Overrides \-\-line\-color. The line will match the {inside, ring} color.
Note: these two options conflict with each other.

.TP
.B \-\-{key, bs}hl\-color=rrggbbaa
Sets the color of highlight arcs on the ring upon keypress and backspace.

.TP
.B \-\-separator\-color=rrggbbaa
Sets the color of the seperators at both ends of the highlight arcs on the ring.

.TP
.B \-\-{verif, wrong, modif}\-color=rrggbbaa
Sets the color of the status text while verifying and when password is wrong.

.TP
.B \-\-{layout, time, date, greeter}\-color=rrggbbaa
Sets text colors.

.TP
.B \-\-time\-str="%H:%M:%S"
Sets the format used for generating the time string.
See strftime(3) for a full list of format specifiers.

.TP
.B \-\-date\-str="%A, %m %Y"
Sets the format used for generating the date string.

.TP
.B \-\-verif\-text="verifying…"
Sets the string to be shown while verifying the password/input/key/etc.

.TP
.B \-\-wrong\-text="wrong!"
Sets the string to be shown upon entering an incorrect password.

.RE

.TP
.B \-\-special\-passthrough
Allows special keys to pass through the locked screen, with \-\-pass\-{media, screen,
power, volume}\-keys. Keystrokes are forcibly sent to the window manager or desktop
environment in three steps: un-grab keyboard, send key, and re-grab the keyboard.
No other keys will be sent to the WM/DE.

Note: ONLY use this option if the special keys are NOT passed through without it.
This could be less safe than the default behavior since the keyboard is ungrabbed for
the keys to be passed through. This HAS been tested though, so there SHOULDN'T be any
security issues.

.TP
.B \-\-bar\-indicator
Replaces the usual ring indicator with a bar indicator. Comes with perks.

.TP
.B \-\-bar\-direction={0, 1, 2}
Sets the direction the bars grow in. 0 is the default (downwards, or rightwards,
depending on the bar orientation). 1 is the reverse, and 2 is both.

.TP
.B \-\-bar\-orientation={vertical,horizontal}
Sets whether the bar is vertically or horizontally oriented.
Defaults to horizontal.

.TP
.B \-\-bar\-step
Sets the step that each bar decreases by when a key is pressed. A random bar is
set to its max height, then each neighbor is set to (height - step*distance).

.TP
.B \-\-bar\-max\-height
The maximum height a bar can get to. When a key is pressed, a random bar is set
to this value, then its neighbors are set to its height, minus the step value.

.TP
.B \-\-bar\-base\-width
The thickness of the "base" bar that all the bars originate from.
This bar also takes on the ring verification and wrong colors to give
authentication feedback.

.TP
.B \-\-bar\-color
Sets the default color of the bar base.

.TP
.B \-\-bar\-periodic\-step
The value by which the bars decrease each time the screen is redrawn.

.TP
.B \-\-bar\-pos
Works similarly to the time/date/indicator expressions. If only one number is
provided, this sets the vertical offset from the top or left edge. If two
numbers are provided in the form of x:y, sets the starting position of the bar.

.TP
.B \-\-bar\-count
Sets the number of minibars to draw on each screen.

.TP
.B \-\-bar\-total\-width
The total width of the bar. Can be an expression.

.TP
.B \-\-redraw\-thread
Starts a separate thread for redrawing the screen. Potentially worse from a
security standpoint, but makes the bar indicator still do its usual periodic
redraws when PAM is authenticating.

.TP
.B \-\-refresh\-rate=seconds\-as\-double
The refresh rate of the indicator, given in seconds. This should automatically
align itself, but is somewhat buggy currently.
Values less than one will work, but may result in poor system performance.

.TP
.B \-\-composite
Some compositors have problems with i3lock trying to render over them, so this
argument is disabled by default. However, some will work properly with it, so
it's been left enabled.

.TP
.B \-\-no\-verify
Do not verify the password entered by the user and unlock immediately.
.B Use only for quickly testing new configurations and remember to remove to
.B actually lock your screen!

.TP
.B \-\-slideshow\-interval
The interval to wait until switching to the next image.

.TP
.B \-\-slideshow\-random\-selection
Randomize the order of the images.
