I cautiously offer that it might have been the screen saver kicking in, but in 
general video doesn't get properly initialized after hibernate. On many machines 
it doesn't need to have the video hardware reset, so it doesn't matter, and I'm 
told that using a vendor driver may solve the problem. That's information, not 
suggestion, treat with care.

One thing which may work, and has worked for me, is to switch to a text mode 
console, and instead of logging in or anything, switch back to the graphic 
screen. I think this resets the video back to a sane graphic mode, but that's a 
guess. Another thing which has worked for me on some laptops is to switch to a 
text mode before doing the hibernate. That implies you know you're going to do 
it. Sometimes killing and restarting X will fix the issue.

May some of this be useful, these are tricks which have worked for me or 
friends, hardware and drivers differ enough for me to help any more.
