Comment 3 for bug 14044

I'm also seeing this (or something similar) when using NVidia Twinview. I can reproduce it in all SDL fullscreen applications, and everything works fine if I manually switch to a single-screen mode before launching the app.

I have the X modes correctly set up, but what happens is that the window is opened spread across two monitors before the mode switch happens - but the window isn't moved afterwards, so I can only see half of it. Moving the mouse around will sometimes cause the window to "scroll" onto the single screen, but then mouse input is screwed up in the game.
