Hi. nVidia has its own Xinerama extension called TwinView. When using multiple monitors/screens in X using the proprietary driver, you should not be using the Xinerama flag.
See nvidia docs on Twinview, and I'm attaching another xorg.conf for your perusal. A bit ugly, my apologies in advance. ** Attachment added: "xorg.conf on my old gentoo box with nvidia proprietary driver." http://librarian.launchpad.net/5989079/xorg.conf -- NVIDIA propietary driver doesn't works with Xinerama https://launchpad.net/bugs/69668 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
