Refer to http://nouveau.freedesktop.org/wiki/CodeNames for details. > I suspect that this is a major part of > the reason why video acceleration is not working. I doubt. For the general review about what is supported by Nouveau for the NV40 family (and other families), refer to the Nouveau feature matrix, at http://nouveau.freedesktop.org/wiki/FeatureMatrix However, I am not sure how much of the current driver's functionality is actually present in the kernel module that comes with CentOS. You didn't specify which version of CentOS you use, but at best (CentOS 6.x) the kernel is from Fedora 12 timeframe. I am not familiar if all the features and bugfixes that have been introduced to Nouveau since that time are actually backported to the CentOS kernel. Not sure if it is even possible. YMMV. If you absolutely need 3D acceleration, maybe take a look at the nvidia proprietary drivers --- you can find CentOS-packaged yum-installable rpm's in elrepo (or was it rpmforge?)... HTH, :-) Marko
