| -batchcount
Number
| Sets the number of things to do per batch. Number
refers to different things depending on the mode:
- qix
- Refers to the number of lines rendered in the same color.
- hop
- Refers to the number of pixels rendered in the same color.
- image
- Refers to the number of sunlogos on screen at once.
- swarm
- Refers to the number of bees
- life and
blank
- Does not apply.
|
| -bg
Color
| Sets the color of the background on the password screen.
|
| -delay
Number
| Sets the speed at which a mode operates to the number of microseconds to
delay between batches of hopalong pixels, qix lines,
life generations, image bits, and swarm
motions.
In the blank mode, it is
important to set this to a small number because the keyboard and mouse are
only checked after each delay. A delay of zero would needlessly consume
the processing unit while checking for mouse and keyboard input in a tight
loop since the blank mode has no work to do.
|
| -display
Display
| Sets the X11 display to lock. The xlock command locks
all available screens on the server and restricts you to locking only a local
server, such as unix:0, localhost:0, or
:0 (unless you set the -remote flag).
|
| -fg
Color
| Sets the color of the text on the password screen.
|
| -font
FontName
| Sets the font to be used on the prompt screen.
|
| -help
| Prints a brief description of available options.
|
| -info
TextString
| Defines an informational message. The default is Enter
password to unlock; select icon to lock.
|
| -invalid
TextString
| Specifies an password message. The default is Invalid
login.
|
| -mode
ModeName
| Specifies one the following six display modes:
- blank
- Displays a black screen.
- hop
- Displays the real plane fractals from the September, 1986 issue of
Scientific American.
- image
- Displays several randomly appearing sun logos.
- life
- Displays Conway's game of life.
- qix
- Displays spinning lines.
- swarm
- Displays a swarm of bees following a wasp.
|
| -nice
NiceLevel
| Sets system nicelevel of the xlock process.
|
| -password
TextString
| Specifies the password prompt string. The default is
Password:.
|
| -saturation
Value
| Sets saturation of the color ramp. A value of 0 (zero) is
grayscale and a value of 1 is very rich color. A value of 0.4 is
a medium pastel.
|
| -timeout
Seconds
| Sets the number of seconds before the password screen times out.
|
| -username
TextString
| Specifies the message shown in front of the user name. The default
is Name:.
|
| -validate
TextString
| Specifies the message that is shown while validating the password.
The default is Validating login....
|
| -/+allowaccess
| Allows the disabling of the access control list, but still causes the
local server to prompt for a password. If xlock is killed
using the -KILL command, the access control list is not
lost.
This flag is also needed when
running the xlock command remotely since access to the control list
is restricted.
|
| -/+allowroot
| Allows the root password to unlock the server as well as the user who
started the xlock command.
|
| -/+echokeys
| Causes the xlock command to echo to screen a '?'
(question mark) character for each key typed into the password prompt.
The default is no echo.
|
| +/-enablesaver
| Enables the default screensaver. It is possible to set delay
parameters long enough to cause phosphor burn on some displays. This
flag can be used as an added precaution.
|
| +/-mono
| Causes the xlock command to display monochrome (black and
white) pixels rather than the default colored ones on color displays.
|
| +/-nolock
| Causes the xlock command to only draw the patterns and not to
lock the display. A keypress or a mouse click terminates the screen
saver.
|
| +/-remote
| Allows remote locking of X11 servers. This flag should be used
with care. It is intended mainly to lock X11 terminals that cannot run
the xlock command locally. If you lock a workstation other
than your own, that person will need your password to unlock it.The
-remote option does not disable your ability to toggle to another
shell.
|
| +/-usefirst
| Allows using the keystroke which obtained the password screen as the
first input character in the password. The default ignores the first
keystroke.
|
| +/-v
| Minus prefix enables the verbose mode to tell which options the
xlock command is going to use. The plus prefix is the
default.
