Now, suppose I don't want to buy another gfx board, but rather connect an external USB-to-VGA adapters like these: http://goo.gl/TqchG Would Fedora recognize the 3rd display (no matter it being much slower due to the USB 2.0 interface) and put the 3rd screen alongside the other two so I can move app windows from one monitor to the next? Or would it be a separate X display because it's handled by a different driver?It might well recognize the usb framebuffer (I have no idea if it will even do that.) The stumbling block will be to get the current Xorg to span two framebuffers. Back in the early days of X11 it did have an extension called Xinerama ( http://en.wikipedia.org/wiki/Xinerama ). That extension appears to have suffered bit-rot and no longer works for me. I tried to get two different Radeon frame buffers to work together but ended up buying a new card that had at least three outputs. Sadly those are hard to come by and they charge an arm and a leg.
I've been researching triple-head for quite a while, and the lest evil option I've come up with is the AMD FirePro 4900. It natively supports triple head from one card, has Linux drivers and config tools available from AMD, and is not horrifically expensive.
Have a look at http://www.amd.com/us/products/workstation/graphics/ati-firepro-3d/Pages/product-comparison.aspx for some comparisons of various video cards including how many monitors they support.
Hope this helps.
