have a problem with getting xinerama to work
my setup is: nvidia ti4200 agp for the center and the right screen and a nvidia tnt2 on pci for the left screen
now, all 3 are working, but xinerama doesn't work on the center and right screen, if I maximise something it goes on both screens, and movies are stretched...
if anybody has an idea of what to do it would be great

here's my xconfig:

That's exactly what I had last time I tried TwinView on my card. Hence I decided it was pretty useless and stuck with seperate screens.

I'm not sure how well Xinerama works with TwinView; twinview makes it look like it's one big screen anyway, so Xinerama probably doesn't know they're actually two seperate ones underneath.
You may well be better off setting them up as seperate screens - IIRC you remove the TwinView stuff, copy the Ti Device section and put "Screen 0" and "Screen 1" in the two Ti devices.
Then running Xinerama over the top of that may get you what you want.

If you need more information, PM me and I'll dig up the xorg.conf off my desktop and post that.

So I'm guessing you have the xinerama working between your two cards but the ti4200 displays aren't? I'm not sure if Nvidia's twinview will handle the xinerama between both cards with three displays, if it does you don't need to specify "xinerama" anywhere in your xorg.conf. Once you have a 9:2 (or whatever) screen that spans all three displays then the xinerama should be handled by your display manager.

You have to use the xinerama use flags for whatever packages have this support and it should work for you. A lot of this can depend on your WM/DE too I suppose. I only use kde and it has really good xinerama support.
