So I have Cedega, and I have two monitors, extending the desktop between them using Xinerama I believe, on an ATI Radeon card. Anyways, when I launch a game, it runs cloned on both monitors. Any easy way I can either limit it to one screen or have it run windowed?

I remember seeing an option like that in the Cedega config file, but I don't have Cedega installed at the moment... maybe try going through the config file, using man or Google
