I wonder if the framebuffer for the second head is too small. By default you only get 8Mb for it and you've a high resolution display. Have you tried using
Option "Crtc2Half" "true" in the device section for both heads? That should split the framebuffer more evenly and might make the second head work better. -- Xinerama broken since intrepid on MGA https://bugs.launchpad.net/bugs/292214 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
