http://ubuntuforums.org – 1) I used the Janitor feature to clean all the "cruft" that has built up since I did a clean install. After I did that I put it to sleep and when I came back 10 minutes later and opened the lid on my laptop the screen was blank except for the mouse cursor which moved around fine. the only way that I have solved the problem was to turn off "lock screen when waking up". 2) if I'm not connected to a wireless network it keeps on trying to connect to a random network that I do not own.
