Prior to Lion I believe moving the mouse woke a sleeping(powersave) screen, and now in Lion you have to click. Often I am in the situation where I am about to go to bed and want to sleep my imac, but am unsure whether the machine is already fully asleep or just the screen. Previously I would simply move the mouse to find out. Now I have to click, which means I wake the machine either way i.e. if it was already off, and then have to shut it down straight after.
Is it possible to bring back waking power saving screen with mouse move?
