    Default Four Screens, two GPU's and one Big Desktop

    Hi. I have the latest catalyst drivers, 8.12 installed on a fresh install of ubuntu 8.10 for amd64. I bought two ATI FireGL V3600's so I can stretch one big desktop across four monitors.

    I am only able to setup two big desktops: one per gpu, but with two screens each. There is no way to join all four screens to one big desktop.

    How can I set it up so that i can have one big desktop across all four monitors without enabling xinerama?

    I really need help getting this to work. Please let me know what information to provide. I have exhausted a lot of resources before coming here.

    I am trying to set it up similiar to this:
    http://www.phoronix.com/forums/showt...2780#post46639

    What are the requirements for setting ATI FireGL V3600 with four monitors all one desktop?

    Am I missing something fundamental here? Do I need a supported Motherboard? Are the V3600's not supported for this?
