vlock-plugins5

Overview

If vlock-main(8) is compiled with plugin support its default features are very limited: it can only lock the current session and ask for authenticiaton. However it is possible to extend this functions through plugins. These plugins are loaded when vlock-main starts and can provide hooks that are called at certain points during the lifetime of the vlock-main process.

Default plugins

The following plugins are provided when installing vlock with default options:

all

This plugin locks all sessions by disabling console switching. It is also loaded when giving the -a,--all option to vlock(1).

new

This plugin switches to a new virtual console before disabling console switching through the "all" plugin. It is also loaded when giving the -n,--new option to vlock(1).

nosysrq

Linux only. This plugin disables the Linux SysRQ mechanism before the console switching is locked by the "all" plugin. It is also loaded when giving the -s,--disable-sysrq option to vlock(1).

Additional plugins

The following plugins are only available if explicitly selected at build time:

caca

This plugin runs a random libcaca screensaver when the screen is locked.
