I also noticed mplayer and Xine also recognized multiple monitors. The Firefox "awesome bar" adjusts where it shows based on the monitor edge that doesn't actually exist in my configuration. I wasn't able to find an option in KDE 4.2 to ignore Xinerama or the like, but haven't looked hard. Something at the xserver level would be nice. A global option or better yet a way to instruct xrandr to treat two or more specified screens as one to all X software. This is basically another feature regression with xrandr and should probably be considered to be resolved in a future revision.
