I open the lid of the laptop and the computer wakes up. I fill in my password and log in. I'm shown the desktop for a second and then the screen goes black. I then have to hit a key or two to wake it up again. Then I'm force to log in once more.
Anyone seen this? How can I fix it?

Make sure you dont have Log-In options enabled. If they are, disable them. It sounds like you might be running a Log-In option.

EDIT: Since you don't have any log in options enabled, it sounds like it might just be a lag from the screen waking up.
Does this happen when you are attached to an external monitor as well? Or does it only occur when you open the lid?
