    Status of Eyefinity Support in Linux

    Hello,

    I am confused about the current state of Eyefinity support in linux. I will say what I want to do and hopefully someone will understand better if it is possible yet.

    So I have 4 DVI monitors that are currently run off nvidia cards, it works ok, could be better. I would like to buy two 5XXX cards with 2 DVI outs each and run the monitors as one big desktop using Eyefinity.

    I think this will be possible in the future but I can't find out if it is now. I have seen the 24 monitor linux demo, off 4 cards. I have also noticed that the windows drivers seem to support 8 monitors off two cards.

    Does anyone know what the state of play is?
    Thanks,
    Phil

    I haven't heard of any ATI-specific replacement for those things, neither of plans to provide any. Then again, there's code in fglrx for multi-GPU-cards, not sure if any of that is usuable with multiple GPUs on separate cards.
    The 24 head demo was done in the following way...

    4 x 6 head 5k family cards. Each card was in a 3x2 config with randr 1.2 The layout of the individual heads was in the obvious 2x2 config.

    The application was X-Plane. X-Plane supports rendering to independent heads (1 master + 3 slaves).

    If you look at the eyefinity video on youtube, you see that the top left occasionally gets out of sync. It's not quite getting out of sync, just the X-Plane predictive camera position doesn't handle the position too well. (It kind of does an extrapolation of where the camera should be, and then occasionally has to adjust it back).

    You are right, Xinerama wouldn't work in that config (too many large surfaces needing to be copied due to X server internals). Well, it did work, but wasn't usable.

    I was under the impression that Eyefinity for Linux was supported on FirePRO products already, and that what's coming down the pipe is support for the much larger range of consumer cards. Not 100% sure though...

    I'm thinking ATI/AMD may want to remove and repost their FirePro Linux driver release notes, as it clearly states Eyefinity support in the "New Features" section (and it does not state Windows only)...
