Funny.. Exactly the same happened to me two days ago. I my xorg.conf (xorg 6.8.2) there were three line:
### Uncomment if you don't want to default to DDC: HorizSync 30.0 - 95.0 VertRefresh 50.0 - 160.0 ..well, and i just uncommented the HorizSync and the VertRefresh - and voila, everything was back to normal. Don't know what it was - hardware seems to be OK. If I remeber correctly I had this problem on every new LFS/BLFS- System i set up.
