|
-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 if your display server is an AIX machine 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. |
