I have the same problem in Ubuntu Oneiric. I have a quite old but strong graphic card GT8800 which playied good in earlier versions(after some tweaking). Now my second monitor is not detected at all.
This is what I get in Nvidia-Settings -> X Server DIsplay Configuration : Unable to load X Server Display Configuration page: Failed to query NoScanout for screen 0. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/539196 Title: nvidia-settings X display configuration window doesn't work on nvidia-173 and nvidia-96 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-settings/+bug/539196/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
