I was wondering if anyone has a working setup of 3 Display's using Xinerama. I have run into what appears to be a hardware limitation or hardware issue in doing this. I have tested using various PCI display cards on both RedHat 9, 8 and 7.3 as well as FreeBSD. The results have always been the same. Two Display's and 2 cards work fine, with 3 Display's they box Freezes shortly after X is started. Most of the time this happens when moving something from one display to another. Usually its only when I move to one display in particular. None of the cards I am using are accelerated, I have tried doing several things, like disable dri or enable dri, but I always have the same results. Interesting thing is when I set up all 3 without using Xinerama, they work fine. That is as seperate display's. I have swapped the cards around, I have changed IRQ Settings many times, but I never can get 3 working without the hard lockups. Keep in mind none of these are dual head cards, and they are not all the same type of card with the exception of being PCI. All three are supported by X and work fine on their own. Detailed configuration data can be provided if you are interested, IE XF86Config, Kernel, hardware type ect..
Just curious if anyone else has run into this.
