I have a similar problem. Running a quad-head with two nvidia cards using xinerama.

The screensaver works normally but sometimes it will crash and blank my main display black and I can't use it after that. The windows are still there but there is a black box over everything I suppose.

I found a work around for my case: run nvidia-settings

It refreshed the main screen and I could see it again without having to restart X.
