dwm is unlikely to be the culprit here, although it also doesn't help
any. dwm only consumes the Xinerama information, it does not perform any
settings itself. So whatever is going wrong is likely to be with the
startup of your X server. I would suggest you investigate how the server
starts in your case, and how it attempts to deal with multiple displays.
