I think only way to play full screen video with no tearing in Natty, is to disable composite extension (see comment #15) Then you need to use classic mode without visual effects (select in login screen). I'm using nvidia 9400M with driver nvidia-current (270.41.06). I tried also nvidia-173, but I could not get vdpau working on it. Can any other nvidia driver to be get working with nutty? I tried several from NVIDIA, but seems those can't compiled or does not work with current X version.
In 10.04 with these settings enabled I had no tearing with full screen video: Workarounds: Legacy fullscreen support General options: Unredirect Fullscreen Windows -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/600178 Title: Screen tearing when dragging window, in videos and other large screen redraws (on nVidia GPU) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
