.SH NAME
i3lock \- slightly improved version of slock
.SH SYNOPSIS
i3lock takes no arguments
.B i3lock
.RB [\|\-v\|]
.RB [\|\-n\|]
.RB [\|\-b\|]
.RB [\|\-d\|]
.SH DESCRIPTION
.B i3lock
@ -37,8 +41,28 @@ does not call XBell(). This is important because
.B i3lock/slock
think you've entered a password when resuming from suspend, at least sometimes.
Since version 1.0, i3lock supports PAM.
.SH OPTIONS
.TP
.B \-v, \-\-version
Display the version of your
.B i3lock
was forked from slock-0.9
.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 \-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).
