Yeah, that's the conclusion I came to. I made the right choice, though. And no miracles here, but I was able to launch Overlord, which I was previously playing at 640x480, and this time I could bump it up all the way to 1024x768! Wow!

I gave up on the Beryl packages because it looks like that's old news. I'm now working to get Compiz installed (they combined with Beryl) using these very good instructions.
