Comment 6 for bug 186153

Yes, I think this is related to bug 40571: screensaver don't work until I set preferences in monitor power savings. The fact is that the power savings preferences are not "remembered". By the way, the screensaver is set after 8 minutes of inactivity, monitor is set to power off at 25 minutes.

Regarding your questions:
