NAME

       i3lock - improved screen locker

SYNOPSIS

       i3lock [-v] [-n] [-b] [-d] [-i image.png] [-c color] [-t] [-p pointer] [-u]

DESCRIPTION

       i3lock 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.

IMPROVEMENTS

       * 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)

       * You can specify either a background color or a PNG image which will be displayed while your screen is locked.

       * You can specify whether i3lock should bell upon a wrong password.

       * i3lock uses PAM and therefore is compatible with LDAP etc.

OPTIONS

       -v, --version
	      Display the version of your i3lock

       -n, --nofork
	      Don't fork after starting.

       -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.

       -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).

       -u, --no-unlock-indicator
	      Disables 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).

       -i path, --image=path
	      Display the given PNG image instead of a blank screen.

       -c rrggbb, --color=rrggbb
	      Turns the screen into the given color instead of white. Color must be given in 6-byte format: rrggbb (i.e. ff0000 is red)

       -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).

       -p win|default, --pointer=win|default
	      If  you specify "default", i3lock does not hide your Mousepointer. If you specify "win", i3lock displays a hardcoded Windows-Pointer
	      (thus enabling you to fuck with your friends by using a Screenshot of a Windows-Desktop as a locking-screen).

XSetScreenSaver()														 XSetScreenSaver()

Name
  XSetScreenSaver - set the parameters of the screen saver.

Synopsis
  XSetScreenSaver(display, timeout, interval, prefer_blanking,
	    allow_exposures)
	Display *display;
	int timeout, interval;
	int prefer_blanking;
	int allow_exposures;

Arguments
  display   Specifies a connection to an X server; returned from XOpenDisplay().

  timeout   Specifies the time of inactivity, in seconds, before the screen saver turns on.

  interval  Specifies  the  interval,  in  seconds,  between  screen saver invocations.  This is for intermittent changes to the display, not
	    blanking.

  prefer_blanking
	    Specifies whether to enable screen blanking.  Possible values are DontPreferBlanking, PreferBlanking, or DefaultBlanking.

  allow_exposures
	    Specifies the current screen saver control values.	Possible values are DontAllowExposures, AllowExposures, or DefaultExposures.

Description
  XSetScreenSaver() sets the parameters that control the screen saver.	timeout and interval are specified in seconds.	 A  positive  timeout
  enables  the	screen	saver.	 A timeout of zero (0) disables the screen saver, while a timeout of -1 restores the default.  An interval of
  zero (0) disables the random pattern motion.	If no input from devices (keyboard, mouse, etc.) is generated for  the	specified  number  of
  timeout seconds, the screen saver is activated.

  For  each screen, if blanking is preferred and the hardware supports video blanking, the screen will simply go blank.  Otherwise, if either
  exposures are allowed or the screen can be regenerated without sending exposure events to clients, the screen is tiled with the root window
  background  tile,  with a random origin, each interval seconds.  Otherwise, the state of the screen does not change.	All screen states are
  restored at the next input from a device.

  If the server-dependent screen saver method supports periodic change, interval serves as a hint about how long the change period should be,
  and  a  value of zero (0) hints that no periodic change should be made.  Examples of ways to change the screen include scrambling the color
  map periodically, moving an icon image about the screen periodically, or tiling the screen with the root window background  tile,  randomly
  reoriginated periodically.

  For more information on the screen saver, see Volume One, Chapter 15, Other Programming Techniques.

Errors
  BadValue  timeout < -1.
