Some follow-up: I can eliminate virt-manager as one of the variables. This behavior can occur even if virt-manager has never been run. And note that power saving *must* kick in; if it's just the screensaver, it seems to work fine. If, however, both screens have blanked themselves and powered down the backlight, this can occur (it happens more than 50% of the time but less than 100%).
