In Ubuntu 12.04 with Unity uses gnome-screensaver. Here it is necessary to configurati.
Istorable it works and does what you need, but some can be turned off. So you need now to restore order.

Puppet ( for example, right here ) will save you.
Well, or Chef.
Well or similar =)

Split configs for the machines and have happiness.
