So, I have an Atom-based box with a GeForce 8400 GS card running to an Epson Powerlite projector. I had it running just fine under 12.04, but today I updated to 12.10. Now, when I boot the system, it gets past BIOS and then goes to a blue screen (no signal).

I'm able to get it "working" if I restart into recovery mode. I get the display as before, but of course everything is slow on the screen. I checked around and saw there was a glitch with drivers, so I installed nvidia drivers (which apparently my system didn't have before, at all).

Unfortunately, I'm still getting the blue screen/no signal problem when I boot in normal mode.

What can I do?
