xss [ -e CommandString ] [ -timeout Seconds ] [ -display DisplayPtr ] [ -v ] [ -fg Color ] [ -bg Color ] [ -geometry wxh+x+y ]
The xss command works with the newly added Massachusetts Institute of Technology (MIT) Screen Saver Extensions in order to implement a user controllable screen saver/lock. This command is designed to improve the security of unattended workstations.
The xss command executes a user-specified command string when it receives a screen saver timeout message, or when the user activates the pushbutton. When no user-specified command is given, the xss command defaults to the xlock command.
Note: The xss command only uses the newly added MIT Screen Saver Extensions. The xss command does not work on an older X server, or when using an older X extension library.
| Item | Description |
|---|---|
| -e CommandString | Sets the xss command to execute when either the screen saver times out, or the user activates the pushbutton. Note that if the CommandString parameter value is longer than one word, it must be surrounded by " " (double quotations). |
| -timeout Seconds | Sets the number of seconds of user inactivity before the screen saver times out, and causes the xss command to run the CommandString parameter. |
| -display DisplayPtr | Sets the connection to the X11 display. |
| -v | Turns on verbose mode. |
| -fg Color | Sets the foreground color of the pushbutton. |
| -bg Color | Sets the background color of the pushbutton. |
| -geometry wxh+x+y | Specifies the size and location of the client window. |
When running remotely and using the -display flag for the xss command, remember that you may also have to use the -display flag option for the command that will be executed by the xss command. See the following running remote example:
xss -display myhost:0 -e "xlock -remote -display myhost:0"xss -e "xlock -nolock"xss -e xlock
