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.

I don't know about the GPU, but the CPU usage, while low, would presumably prevent the CPU from going to sleep when it otherwise might, and the power usage there should be significant. I agree with Martin that we should default to, simple idle blanking when running on battery power. --   - mdz -- ubuntu-desktop mailing list <a href="mailto:ubuntu-desktop@lists.ubuntu.com">ubuntu-desktop@lists.ubuntu.com</a> <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-desktop">https://lists.ubuntu.com/mailman/listinfo/ubuntu-desktop</a> </blockquote></div>
