        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 would like to buy two 5XXX cards with 2 DVI outs each and run the monitors as one big desktop using Eyefinity."

        a single hd5850 (5 monitors) can handle this don't waste your time on 'crossfire'!

        i think a 5770 can handle '4 monitors' and a 5870 can handle 6 monitors..

        but you need cataylst 10-7 for more than 2 monitors! the new limit is 24 monitors! (4 pices of 5870 in crossfire)

        windows7 can only handle 8 monitors.

        linux-catalyst 10-7 can handle more than windows ;-)

          10-7 ;-) its a feature in the beta driver..

            On the other hand, the list is from Quridarium, so the big question is if it is real.
            hey i just copy past the list ;-)

            do you think i wrote my own catalyst chancelog??? ? ? ? ?

            hell no!

            Eyfinity is in the 10-7 driver be happy :-)

                  Heck, it could be after the sun has collapsed down to a white dwarf...

                  ... but probably won't be that long either

                      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)...

                        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...

                          Take a pic of it together with an open amdcccle tool that shows the version.

                            i also think bridgman is wrong about the eyefinity support on firegl cards,..

                            but yes how cares 10-7 fix that.

                              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.
