Description
scolock locks your display by
preventing mouse and keyboard input from having any effects on
your computer system. After scolock is activated, your
screen is filled with rotating objects, which spin around the
screen. Any movement with the
mouse or activity on the keyboard brings up a dialog box requesting
your password. Entering the password unlocks your display.
scolock also allows you to activate a screen saver.
NOTE:
Save your current session before locking your display.
Your desktop information is not saved if the system crashes while
your display is locked.
You can change the objects that display by dropping the new
objects onto the Lock icon. You can also have a blank
screen appear when the display is locked rather than any
objects, as described below.
Command options
You can use the following options with the scolock command:
-icons-
causes icons to be displayed rather than worlds or a blank screen.
-worlds-
causes worlds to be displayed. Used as an argument to this option,
-numworlds n determines how many worlds are displayed.
-blank-
causes a blank screen to be displayed rather than objects.
-frames n-
sets the number of frames used in each spinning of an
object (the higher the number, the smoother the spin
and the slower the animation). A typical value is 30.
-framerate n-
sets the rate at which to animate the rotation of the objects.
A typical value is 1.
-norotate-
causes the objects to not rotate.
-autolock-
causes the system to lock automatically.
-screensaver-
activates the screen saver feature.
-delay n-
sets the time it takes (in seconds) for the screen to lock. A typical value is
600.
-lockout n-
sets the time between attempts to enter the password. A typical value is 5
(in seconds).
Resources
You can customize the characteristics of scolock using your
personal X resource file,
$HOME/.Xdefaults-hostname, where
-hostname is the name of the machine on which the client
is running. If this file does not exist in your home directory,
you will need to create it. Changes made to this file take effect
the next time you run scolock.
scolock defines the following application-specific
resources:
icons-
to have icons (rather than worlds) rotate on the screen.
The default is True.
worlds -
to have worlds (rather than icons) rotate on the screen.
The default is False.
blankScreen-
to have the screen blank when the display is locked (that is,
neither icons nor worlds are displayed).
The default is False.
frames-
specifies the number of frames to be used during the rotation
of icons. Higher numbers cause the spin to be smoother
and the animation to be slower. A typical default value is 30.
(When rotating worlds, the value is always 30.)
frameRate-
specifies the rate at which frames are redisplayed.
A typical default value is 1.
noRotate-
disables or enables rotation of worlds/icons.
The default is False.
autoLock-
locks the screen with a password.
The default is False.
screenSaver-
specifies if the screen saver feature is activated.
The default is False.
delay-
specifies the time in seconds
before the screen saver comes on. A typical default value is 600.
lockoutDelay-
specifies the time in seconds between a password error and the
redisplay of the password window. A typical default value is 5.
autoUnmapDelay-
specifies the time in seconds until the password window is visible.
A typical default value is 60.
noRootPassword-
specifies that only the user's password can be used to unlock the
display when set to True (the default). If False, enables the root
password to be entered to unlock the display.
cursor-
determines the password dialog mouse cursor to use for the login window.
The default is left_ptr.
lockNice-
specifies how much CPU time is used for the screen lock. A typical
default value is 0; however, a value such as 5 causes the screen lock
to use up less CPU time.
saveNice-
specifies how much CPU time is used for the screen saver. A typical
default value is 0; however, a value such as 5 causes the screen saver
to use up less CPU time.
loginString-
specifies the password dialog box prompt.
The default is ``Enter your login password''.
