Every time I close my laptop's lid and open it again -- screen stays black and there is no mouse cursor.
I can switch to text console (Alt-Ctrl-F1) and back to black X screen (Alt-Ctrl-F7). I can login in console.

I found that sometimes when I close lid without locking the screen, the latest picture stays on a screen and mouse cursor is shown, but I cannot press anything on the screen.

There was no this bug in 3.0.0 (3.0.0.17.20 -- ubuntu build)

My laptop is Dell Inspiron 1520
My video is NVidia GeForce 8400M
I'm using free nouveau driver.
