No, Mark. "That" wasn't _a_ problem. It was _the_ problem. Thanks. The order in which I tried things was my un-doing. I first began to suspect KDE, itself, was the culprit, but didn't at the time know about the need to "enable" xinerama in the Control Center. Then I began to suspect TwinView and so decided to try the "pure xinerama" route---which among other things, required the explicit xinerama option in XF86Config. When I couldn't even get Xinerama to work you informed me that the binary driver does not support "pure xinerama" on a single card but assured me that TwinView did the proper advertising of the necessary parameters. So back to KDE, and suspicion of it's compilation flags. By this time I had put XF86Config back to "twinview" but saw no harm in leaving in the explicit Xinerama option. (Ha!) More e-mails to various lists, more scouring the web, more hours of wasted time. Finally the "little C program that could" thanks to Balaji Ramani from the Mandrake-experts list. Now KDE is xinerama-aware. The grayed-out options are black and the C program says xinerama is enabled. I'm a "happy camper"---at least for today. I must say that there is precious little good documentation on this. The xinerama-HOWTO is needs to be updated to mention that KDE-2.2.2 is definitely (at least somewhat) Xinerama-aware, but needs to be compiled appropriately and the option needs to be enabled. Actually the better place is the KDE docs. They are, unfortunately, silent or mis-leading on these issues. I suggest that an explicit warning be put into the Nvidia TwinView ReadMe saying that specifying "xinerama on" (I suppose `startx -- +xinerama', or some-such, would also break things) in XF86Config will keep the nvidia xinerama extensions from loading, and hence will prevent window-managers from being xinerama-aware when a single two-port nvidia graphics card is involved. >From my reading on the internet, there is great confusion about xinerama, xinerama-awareness, &c., and such a statement in your ReadMe can only help disentangle it.
