I've just updated my macbook pro 15" retina with Macbook Air and MacBook Pro Update 2.0 from App store (just this update).

After that, every time it goes on the screen saver or if I close it, I can't get it back on, the screen starts flicking black.

There is no away I can enter the password, even the keyboard is flicking.

I have to force the macbook pro power off and on in order to use it.

The update is this http://support.apple.com/kb/DL1609

How can I solve this?

MacBook Pro with Retina display, OS X Mountain Lion (10.8.2), MacBook Air and MacBook Pro Up 2.0
