slock1

Usage

Overview

slock is a simple X screen locker. If provided, cmd is executed after the screen has been locked.

The options are as follows:

-v

Print version information to stdout and exit.

Exit status

The slock utility exits 0 on success, and >0 if an error occurs.

Examples

$ slock /usr/sbin/s2ram

Security considerations

To make sure a locked screen can not be bypassed by switching VTs or killing the X server with Ctrl+Alt+Backspace, it is recommended to disable both in xorg.conf(5) for maximum security:

Section "ServerFlags"
	Option "DontVTSwitch" "True"
	Option "DontZap"      "True"
EndSection

Customization

slock can be customized by creating a custom config.h from config.def.h and (re)compiling the source code. This keeps it fast, secure and simple.
