Comment 8 for bug 45883

I am not sure why the backlight signaling is relevant here. What I see is a problem, is that the sleep function starts a screensaver before sending the computer off to sleep. I understand that it does this as a way to have the screen locked at resume, but in that case it should start a "throttled" screensaver which just blanks (and locks) the screen.

I don't think this has anything to do with my hardware or configuration (except having set the screensaver preference to something else than "Blank") so I think anyone can confirm this by noticing a screensaver starting just before the computer goes to sleep. Unless your hardware is so fast that you can't catch it.
