Guilherme, when configuring for the nvidia driver, you have to do a few things a bit differently than with the nv driver. I've attached my xorg.conf which you could use as an example.
When I use the nvidia driver without setting Screen X in each device section, I also see the "Screen X shares mem & io resources" error messages. ** Attachment added: "Example of a working xorg.conf specifying Screen X" http://librarian.launchpad.net/5666803/xorg.conf -- NVIDIA propietary driver doesn't works with Xinerama https://launchpad.net/bugs/69668 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
