My new installation of Ubuntu 10.10 by default locks the screen after doing nothing for 5 minutes. This is just what I want, but after that I am not able to unlock it again. The screen remains black when I move or click the mouse or even if I push a button on the keyboard.

I still found a workaround:

  • press Ctrl+Alt+F8
  • wait some seconds (the annoying part)
  • press Ctrl+Alt+F7

Any idea what's wrong?

Hardware details:

  • HP EliteBook 8440p
  • Graphic card: NVIDIA NVS 3100M
  • Driver: nvidia-current 260.19.06
