Andrew Gaul, I don't think this is related to bug 1311724. Again my settings are
* Security & Privacy > Prompt for password upon Waking from suspend and Returning from blank screen
* Power > When the lid is closed Do nothing.
I don't want my MacBook Air to suspend, just turn off the backlight. Opening and closing the lid does nothing, I just see the lock screen.
So I think the actual sequence is I close lid, the Unity desktop turns off the backlight (good!), then the Ubuntu lock screen (lightdm?) takes over as I requested (good). Lightdm turns the backlight back on (bad) and thereafter does nothing on additional lid close/open events (bad). I don't know what's causing the backlight cycling off and on thereafter.
