    Phoronix: Nouveau To Enter The Ubuntu 10.04 LTS Kernel

    The Nouveau driver, the X.Org project designed to provide a open-source NVIDIA graphics driver for Linux with 2D/3D/Video acceleration that's developed by cleanly reverse-engineering NVIDIA's binary driver, is about to get promoted in Ubuntu 10.04 LTS. The Nouveau project has been around for years now and continues to make progress but there has yet to be a stable release of any component -- even just a DDX driver -- although their current feature matrix is reflecting that 2D and X-Video support is complete for all NVIDIA graphics hardware generations, many output-related features (RandR 1.2, KMS, NouveauFB) are done, and the 3D work using Gallium3D is even progressing...

    it doesn't make a hell of a lot of difference until we get 3D working

    That's unfortunate though as it'll lock cards to something as low as 1/3 of their performance. Let's hope it doesn't take them too long to figure out the 'upclocking'.

    In any case, nouveau's in no different position to nv or vesa in that regard.

    Aside from that, there's really nothing we can do at this point. With our current knowledge, we'd likely do more harm than good even attempting to control the GPU performance levels."

    So, there's the story.

    Yup This only affects later generation nVidia cards so if you're having a GeForce 6 series or below then you're good with the Nouveau driver

    I?ve been testing nouveau with the fedora betas since f11 on my nvidia collection and had no such problems so far.

    Nah hes just saying that because although open nouveau is essentially a reverse engineered driver where the open ati one is documented and within a year or so should support 3d on all cards. It's running on all but the latest chipset at the moment in some form or another.

    If you decide to use the Nouveau driver anyway then I'd like to kindly advice you to get an ATI card somewhere around januari next year...

    Anyway, what happens when you install the proprietary nvidia driver? Does KMS get disabled when the nvidia module gets loaded?

    I don't think loading both nouveau and nvidia kernel modules will give desirable results.
