Hi there, I'm trying to setting up a Dual Monitor environment on Fedora 18. With a fresh installation (before any update), all was working correctly. From the first update since now, my dual monitor configuration doesn't work. It means that the video on secondary monitor blinks.

OS: Fedora 18; Video card: ATI Radeon HD 6950; DE: Mate + Compiz
