xautolock
An automatic X screen-locker/screen-saver
Xautolock monitors console activity under the X window system, and fires up a program of your choice if nothing happens during a user configurable period of time. You can use this to automatically start up a screen locker in case you tend to forget to do so manually before having a coffee break.
