1. During "sleep" the internal display appears to be powered off but the external is blank but powered on (which means it glows in the dark).
2. I tried to reproduce the behavior by "suspending". When I resumed both displays turned on but instead of a mouse cursor there was a huge white rectangle on the login screen. After I clicked, moved it around the normal cursor appeared.
Some additional information + the included log.
