Change the default screensaver from black to ubuntu logo

[Odysseus Flappington]

I've been using Ubuntu with autosuspend turned on for 2 years now, and it
has never inhibited the autosuspend due to CPU usage. Be it while installing
packages, burning cds, playing mp3s, much less showing a screensaver.

If the inhibit sleep on CPU load was ever implemented, it never worked.

I believe defaulting to a real screensaver is much more sensible, the
parents love stuff like that, even if it means having to detect whether the
laptop is on battery or plugged in.
