.SH DESCRIPTION
.B i3lock
-locks your screen by making it white (default). To quit
-.B i3lock
-just enter your password.
+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 DIFFERENCES TO SLOCK
+.SH IMPROVEMENTS
-.B i3lock
-improves slock by making it fork() and therefore combinable with
-commands to suspend your computer. Additionally, instead of turning off
-your screen via DPMS and/or displaying a black screen,
-.B i3lock
-displays a white screen so you can see if your computer failed to resume
-from suspend or if your screen is just locked. Also, when entering a wrong
-password,
-.B i3lock
-does not call XBell(). This is important because
-.B i3lock/slock
-think you've entered a password when resuming from suspend, at least sometimes.
+.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.
-Since version 1.0, i3lock supports PAM.
.SH OPTIONS
.TP
like when opening your laptop in a boring lecture.
.TP
-.B \-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).
+.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 \-c\ rrggbb \fR,\ \fB\-\-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).
+
+.TP
+.B \-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).
+
+.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 \-i, \-\-image
-Display the given XPM image instead of a blank screen. You can convert an image to
-XPM by using convert(1) from ImageMagick or GIMP for example.
+.B \-l, \-\-lock-console
+Lock the console to disable TTY switching (Linux only).
.TP
-.B \-c, \-\-color
-Turns the screen into the given color instead of white. Color must be given in 6-byte format: rrggbb (i.e. ff0000 is red)
+.B \-\-debug
+Enables debug logging.
+Note, that this will log the password used for authentication to stdout.
+
+.SH 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:
+
+.Vb 6
+\& #!/bin/sh
+\& revert() {
+\& xset dpms 0 0 0
+\& }
+\& trap revert HUP INT TERM
+\& xset +dpms dpms 5 5 5
+\& i3lock -n
+\& revert
+.Ve
+
+The \-I (-\-inactivity-timeout=seconds) was removed because it only makes sense with DPMS.
+
