NAME

xlock - Locks the local X display until a password is entered.

SYNOPSIS

DESCRIPTION

If the correct password is typed, then the screen is unlocked and the X server is restored. When typing the password Control-U and Control-H are active as kill and erase respectively. To return to the locked screen, click in the small icon version of the changing pattern.

In the lower part of the password screen a text is displayed. This message is taken from the first file of the following that exists: $HOME/.xlocktext, $HOME/.plan, or $HOME/.signature.

On systems which support new BSD style authentication, the password may be prefixed by an authentication style followed by a colon (i.e. "style:password"). See the login.conf(5) for more information on authentication styles.

NOTE ON ETIQUETTE

If you find a public terminal that has been locked by another user and there are no other terminals available, and the terminal appears to have been left idle for a while (normally more than 15 minutes), it is fair to try to reset the session in some manner.

OPTIONS

-help

Print options and a brief description to standard output.

-version

Print version number (if >= 4.00) to standard output.

-resources

-display displayname

The display option sets the X11 display to lock. xlock locks all available screens on a given server, and restricts you to locking only a local server such as unix:0, localhost:0, or :0 unless you set the -remote option.

-visual visualname

-delay usecs

The delay option sets the speed at which a mode will operate. It simply sets the number of microseconds to delay between batches of animations. In blank mode, it is important to set this to some small number of seconds, because the keyboard and mouse are only checked after each delay, so you cannot set the delay too high, but a delay of zero would needlessly consume cpu checking for mouse and keyboard input in a tight loop, since blank mode has no work to do.

In fire, gears, sballs and sproingies it is the size of the screen, this is because on many slow systems it runs too slow when the picture covers the full screen.

-ncolors num

The ncolors option sets the maximum number of colors to be used.

-saturation value

The saturation option sets saturation of the color ramp used to value . 0 is grayscale and 1 is very rich color. 0.4 is a nice pastel.

-erasemode modename

As of this writing there are over 9 erase modes supported (if its not chosen its assumed random). The erase modes are random_lines, random_squares, venetian, triple_wipe, quad_wipe, circle_wipe, three_circle_wipe, squaretate, no_fade.

-erasedelay usecs

The erasedelay option sets the number of microseconds for steps of the erasemode (a setting of 0 and the erasemode is bypassed).

+/-nolock

The nolock option causes xlock to only draw the patterns and not lock the display. A key press or a mouse click will terminate the screen saver.

-/+inwindow

Runs xlock in a window, so that you can iconify, move, or resize it and still use your screen for other stuff. When running in a window, xlock no longer locks your screen, it just looks good.

-/+inroot

Runs xlock in your root window. Like the inwindow option it no longer locks the screen, it just looks good.

-/+remote

The remote option tells xlock to not stop you from locking remote X11 servers. This option should be used with care and is intended mainly to lock X11 terminals which cannot run xlock locally. If you lock someone else's workstation, they will have to know your password to unlock it. Using +remote overrides any resource derived values for remote and prevents xlock from being used to lock other X11 servers. (Use `+' instead of `-' to override resources for other options that can take the `+' modifier similarly.)

-/+mono

The mono option causes xlock to display monochrome, (black and white) pixels rather than the default colored ones on color displays.

-/+allowaccess

This option is required for servers which do not allow clients to modify the host access control list. It is also useful if you need to run x clients on a server which is locked for some reason... When allowaccess is true, the X11 server is left open for clients to attach and thus lowers the inherent security of this lock screen. A side effect of using this option is that if xlock is killed -KILL, the access control list is not lost.

-vtlock modename

This option is used on a XFree86 system to manage VT switching in [off|noswitch|switch|restore] mode.

off

means no VT switch locking.

switch

means VT switch locking + switching to xlock VT when activated.

restore

means VT switch locking + switching to xlock VT when activated + switching back to previous VT when desactivated.

noswitch

means VT switch locking only when xlock VT is active.

-/+allowroot

The allowroot option allows the root password to unlock the server as well as the user who started xlock. May not be able to turn this on and off depending on your system and how xlock was configured.

-/+debug

Allows xlock to be debugged by doing all but locking the screen.

-/+description

The description option causes xlock shows a mode description above password window. The default is to show this description.

-/+echokeys

The echokeys option causes xlock to echo '?' characters for each key typed into the password prompt. Some consider this a security risk, so the default is to not echo anything.

-/+enablesaver

By default xlock will disable the normal X server's screen saver since it is in effect a replacement for it. Since it is possible to set delay parameters long enough to cause phosphor burn on some displays, this option will turn back on the default screen saver which is very careful to keep most of the screen black.

-/+resetsaver

By default xlock will call XResetScreenSaver. This may be undesirable with DPMS monitors.

-/+grabmouse

The grabmouse option causes xlock to grab the mouse and keyboard, this is the default. xlock can not lock the screen without this.

-/+grabserver

The grabserver option causes xlock to grab the server. This is not usually needed but some unsecure X servers can be defeated without this.

-/+install

Allows xlock to install its own colormap if xlock runs out of colors. May not work on with some window managers (fvwm) and does not work with the -inroot option.

-/+mousemotion

Allows you to turn on and off the sensitivity to the mouse to bring up the password window.

-/+sound

Allows you to turn on and off sound if installed with the capability.

-/+timeelapsed

Allows you to find out how long a machine is locked so you can complain to an administrator that someone is hogging a machine.

-/+usefirst

The usefirst option causes xlock to use the keystroke which got you to the password screen as the first character in the password. The default is to ignore the first key pressed.

-/+verbose

Verbose mode, tells what options it is going to use.

-nice nicelevel

The nice option sets system nicelevel of the xlock process to nicelevel .

-lockdelay seconds

The lockdelay option sets the number of seconds before the screen needs a password to be unlocked. Good for use with an autolocking mechanism like xautolock(1).

-timeout seconds

The timeout option sets the number of seconds before the password screen will time out.

-font fontname

The font option sets the font to be used on the prompt screen.

-planfont fontname

option sets the font to be used for the text that is displayed in the lower part of the password screen.

-fg color

The fg option sets the color of the text on the password screen to color .

-bg color

The bg option sets the color of the background on the password screen to color .

-foreground color

The foreground option sets the color of the text on the password screen to color .

-background color

The background option sets the color of the background on the password screen to color .

-username string

Text string is shown in front of user name, defaults to "Name: ".

Text string is an informational message to tell the user what to do, defaults to "Enter password to unlock; select icon to lock.".

-validate string

Text string is a message shown while validating the password, defaults to "Validating login..."

-invalid string

Text string is a message shown when password is invalid, defaults to "Invalid login."

-geometry geom

The geometry option sets geom the size and offset of the lock window (normally the entire screen). The entire screen format is still used for entering the password. The purpose is to see the screen even though it is locked. This should be used with caution since many of the modes will fail if the windows are far from square or are too small (size must be greater than 0x0). This should also be used with -enablesaver to protect screen from phosphor burn.

-icongeometry geom

The icongeometry option sets geom the size of the iconic screen (normally 64x64) seen when entering the password. This should be used with caution since many of the modes will fail if the windows are far from square or are too small (size must be greater than 0x0). The greatest size is 256x256. There should be some limit so users could see who has locked the screen. Position information of icon is ignored.

-glgeometry geom

The glgeometry option sets geom the size of the screen for gl modes. Not normally available or needed.
