One thing that I was lucky to find out about right as I was attempting to setup Beryl is a very handy little Python app called Envy that not only downloads and applies the latest driver for your video card, but configures your xorg file for you. I had installed Beryl and was of course having issues prior to trying this, but after running Envy and restarting, I had a flawless Beryl running and have not had any issues since.
