http://askubuntu.com – Running Ubuntu 12.04 Unity with kernel 3.4.0-030400-generic on a laptop, when I lock with ctrl + alt + L and close the lid, then open the lid, I expect to see a prompt asking for password, but instead all that is visible is the current desktop background, and mouse cursor. This happens immediately after lid is closed and opened. Suspend on lid close is off. When moving mouse around the middle of the screen, it changes shape as if there was a textbox under it (the password prompt), implying there is something there, just not rendered. I can ctrl + alt + F1 to tty and restart the laptop, but, (HowTos)
