I have this too. I believe it has to do with a changed power state (or however you call this) since the moment of suspension / hibernation. I think it's even reproducable:

 

1. Have your PC plugged on AC (respectively not)

 

2. Suspend / hibernate your PC

 

3. Unplug (respectively do connect to charger)

 

4. Resume & login, voilà!

 

So what I started doing is e.g. first unplug my laptop before I suspend and leave home... You can imagine.

 

A graphics driver issue?

I have the same screen problem twice after I upgraded the latest Inter GM45 Video card driver. So I think the video card driver has some problem. So don't upgrade it.
