    the nvidia drivers simply replace whole parts of the X stack with their own implementations. In some ways, nvidia's implementations are superior, in others, they aren't. And of course they don't benefit from improvements in the replaced open source parts.

    fglrx replaces some parts, too, but IIRC they are less intrusive than nvidia.

    so no, they don't have a problem with the "X stack" in general. But as proper multiseat will rely on pretty new techniques, nvidia may not support it. fglrx may not, either.


    I think multiseat will require KMS, which cannot be supported in any closed source driver. Other multiseat implementations (i.e. based on MPX) may work.

      nVidia is preoccupied with a driver that does 3D to the point where they've ignored pretty much everything else; for example when KDE 4.0 came out it was unusable on nv cards because they had no 2D accel whatsoever.

      You'd be lucky if they support multiseat at all, and even then the ability to use your setup as intended is entirely at their whim - they drop support for older cards just like ATI, but they won't lift a single finger to help FOSS developers make a replacement driver. Using nVidia is an upgrade treadmill, much like using Windows.

        To be honest the only free multiseat solution I'm aware of (free for 2 user only ) is this one:
        http://www2.userful.com/products/userful-multiplier
        and on the specification requirement pdf (which is a bit outdated ) for the nvidia cards support propietary driver is required (is not required for ati card) so I guess the application should work with Nvidia driver.
        Then if you know a better free multiseat application which doesn't have problems with ati and nvidia card feel free to suggest.

          Any examples Ant P? in my experience nvidia keeps supporting old cards. For example i'm still using a 4200 and i've seen on their site legacy drivers for much older cards.

            Did they change their policies at some point without telling anyone? ISTR an announcement where they would no longer support most of their pre-PCIE cards in their next release, shortly after introducing the black window bug in compiz.

              I can very much recommend this Greasemonkey script:
