There's a way this could be improved. We previously had to dim the
screen before CPU sleep because we weren't going to get a chance to
dim it later -- once the CPU is off, it stays off. Now that we have
wakeup timers, we could do something like this:
idle+30s: CPU sleeps
idle+2m: wakeup to dim the backlight, back to sleep
idle+5m: wakeup to turn off the screen, back to sleep
I'm not yet entirely convinced that we should wait that long, though.
Anyone who has used a laptop running OS X will have noticed that it
dims the backlight after just a few (ten?) seconds of inactivity.
I'll add this topic to the talk. Thanks!
