My video drivers are noted as experimental however all features and 3D support is working in Ubuntu 11.04 gnome environment. I did not use the .run file downloadable from the Nvidea website. I have read the sticky about no sound. I have no sound right now. Modern Warfare 2 craps out with a "Direct X has encountered an error". If I can get this working in Ubuntu 11.04 Natty I will no longer have to boot into Windows 7 for anything. It is like the holy grail for me of Linux computing. Does anyone know why I am getting a "Direct X has encountered an error" dialog? >From your description it sounds like you're using the Nouveau driver; you need to install the proprietary Nvidia driver. Open source drivers are not adequate to run 3D games in Wine. http://wiki.winehq.org/FAQ#head-a96989ff3303c1f6c35a1f85e0680b7f6bcfd16f
