    Phoronix: Multi-GPU Lucid Hydra On Linux: No Plans Yet

    Last year the Lucid Hydra 200 was announced as a unique, universal multi-GPU solution. The Hydra 200 is a custom chipset that allows the graphics rendering workload to be split between multiple graphics processors, but the graphics cards do not need to be tied to a particular vendor...

    Yah - the eyefinity stuff might save the day with a 6 port card, but I was unable to get 2 3port eyefinity cards to work correctly under ubuntu Karmic..

    This has been the best we've accomplished:

    We have several clients that had to choose windows because they had 3 or more monitors.. Linux just can't do it right.

    With fglrx, you can do that with 3 monitors on shipping cards and up to six with future cards. It's one surface with RANDR viewports over it, so composite does work.

    However, lots of apps get very confused about the "fullscreen" and mixture of xinerama and randr information. This makes compiz not quite the experience you'd expect.

    which will probably run at 10% the speed if you just used opengl directly

    Not necessarily true, anywhere where a high performance graphics workstation is needed multi GPU solutions can help greatly (Maya, PRO/e, even blender, etc). Also where the Hydra is a different solution is that unlike other competing technologies the method of rendering is very different the traditional slr/afr methods and could at least in theory could allow far more complex rendering.

    That's the point.
