I currently have an AGP Number Nine Revlution 4 32MB as primary, and a PCI ATI @ Work 98 8MB (I think) as a slave. Both heads at 1024x768, and both on 20" monitors. This setup works fine for normal business type apps, programing, web browsing, etc.
I'm using the Xinerama extension, so both heads combine to just one wide display split across two monitors. You can drag windows across the screens, have one window fill up both screens, etc. There are some limitations though: I haven't found any window managers (as of about 6 months ago) that were fully Xinerama/multi-head aware. This is mostly just an annoyance. When an app starts up, it can be split across the screens, a menu from your left screen can overlap to the right screen, etc. No DGA support. If you use VMWare, don't expect full screen mode. This can hamper your use of VMWare, expecially if you run graphics intence apps under vmware. My use of windows apps is very minimal, so this doesn't bother me much. I just ran into this one, only one screen can support openGL, and as far as I can tell, only the primary screen. I just started playing around with some 3D modeling, and the app I'm using requires openGL. The app runs fine as long as it stays on the primary screen. But since the window manager isn't fully aware, it's next to impossible to stay on one screen. This creates a good bit of flakiness in the app, and seems to cause flakiness in X it's self. Now my main Video card doesn't support openGL acceleration, which I believe is causing X windows to be flaky. I have since started to run a second X server on display :1, without Xinerama, when I run this 3D modeler (still flaky, but I believe it's my video card). Recent messages on this list lead me to think that Matrox G450 and G550 dual head cards will support openGL on both heads. I've always heard matrox cards to be more multi-head friendly than others, so this makes since to me. Any how that's my next step, a G550. I probably won't get to it till after new years, so if you go this route post back with your results.
