Same issue here. Samsung laptop R580 with NVIDIA 340.96 drivers -- After figuring out how to fix the Fn control keys for brightness, I have it setup so that after 15 minutes of inactivity the screen goes dark and it asks for password when moving the mouse or pressing a key.
After logging back in, RANDOMLY it flickers/flashes the screen, goes black again on and off, then it goes back to asking for password again, after entering password again it might work fine after a few flickers, or it just gets frozen that there's no other option but a hard shut down.
Last night I discovered that while listening to Pandora online and of course after the 15 minutes of inactivity, the screen goes dark (as intended) but the music completely stops.
Thanks.
