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 IMPROVEMENTS + +.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 x:. 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 + +.BR +You can use ImageMagick’s +.IR convert(1) +program to feed raw images into i3lock: + +.BR +.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. + +.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 \-\-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. + +.SH SEE ALSO +.IR xautolock(1) +\- use i3lock as your screen saver + +.IR convert(1) +\- feed a wide variety of image formats to i3lock + +.SH AUTHOR +Michael Stapelberg + +Jan-Erik Rediger -- cgit v1.3
