.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).
