I have a 3 monitor setup on 2 video cards (nvidia and onboard intel) and they all work, however not quite the way I'd like. When it was just the 2 monitors on the nvidia, Openbox would treat them as a single desktop/worksapce but still as separate monitors and allow me to full screen an app on just that one monitor. Now that i have the other card and monitor active (on its own xserver), the 2 nvidia monitors act as a single screen and apps full screen across both. GDM treats each monitor individually (login prompt centers on Screen0, Screen1 has wallpaper, Screen2 is just plain X) but once i get into openbox the nvidia's merge, centering everything between them and the intel behaves as normal. Does anyone have any idea how to retain the dual monitor behaviour for the nvidia screens?
