How is this wrong? I thought the whole point of Xinerama was to combine two or more actual screens into a single virtual screen. Of course, if two screens of different height are joined left-right -- or different width joined top-bottom -- there's going to be a rectangle of the virtual screen that does not exist on either actual screen, hence the original question of how to tell FVWM to block out that area.
