What video hardware are you using, and what driver? |

I've had similar issues in the past myself with a variety of causes: |

- dodgy versions of mesa |
21 |
- dodgy versions of video drivers (both nouveau and radeon) |
22 |
- incorrect kernel settings, usually getting KMS wrong |
23 |
- incompatible combinations of framebuffer and KMS |
