This is correct and suggest that you are *not* using Dynamic Twinview. Which means that your window manager is ignoring those settings from the xinerama extension. Does the problem persist if you use metacity?
In ccsm --> general options --> display settings, is "Detect Outputs" enabled?
No it doesn't, and I think we're getting closer to the root problem here. Metacity is the window manager used when I select 'Failsafe Login' from GDM, correct?
Ever since I upgraded to Ubuntu 10.04, Compiz does not start properly on login to GDM. If I login normally, I dont have a window manager for my windows: there is no window decoration, I can't use alt-tab to application switch, etc.. So what I've been doing is dropping to a virtual console and running 'compiz --replace' from the command line, switching back and voila! I have window decorations and a window manager BUT I have the problem I posted initially.
If I login with 'Failsafe GNOME', I have the monitor behavior I expect, where windows snap to each but I dont have Compiz turned on.
It sounds like maybe I need to figure out why Compiz doesnt start when I login to Gnome regularly?
