Isn't it in the settings? I think you can decide how long you want the screen saver to show then the screen goes black and wake up if you touch your mouse or keyboard.

When the screensaver has been running for about 15 minutes it then becomes a black screen. Does anyone know the reason for this? geoffrey -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </blockquote></div>
