Public bug reported:
I closed the lid of my laptop, and when I open it up to unlock the screen, it
shows nothing except blurred screen with black and white dot mixed. But when I
moved the mouse or push any key, the blurred screen disappeared.
My laptop uses a Core i5 460m CPU and NVIDIA GT425M graph card. But I haven't
installed any graph card drive.
I use GNOME Clissic (No effects) environment.
My Ubuntu version is 12.04.1 LTS.
