> Unfortunately this does not seem to be the problem on nvidia cards. The disabling of Int10 is necessary for SiS and other chipsets, but does not seem to affect nvidia proprietary driver. Still, you might try. But I must warn you that we never got stability on NVidia cards. After some restarts or when running xscreensaver on all heads at once for some time, some devices freeze. We wrote a bugreport for NVidia, but had no answer until now. Perhaps you could do the same (using their nvidia-bug-report.sh), and so we could try to put some pressure.

xorg.conf.probe solution seems to be what I need, but
The .probe solution is because we only use int10 once, in Xinerama mode, before actually starting the different X

1. Are you using only one secondary card, with
multiple ports? If so, which board is it? We are
seeking a reliable, inexpensive multiport board.

No. We are using multiple single cards. SiS315 chipset in most cases. I never tried the

2. In our case, we have multiple secondary cards which
must be initialized. Shouldn't we be using the
"SingleCard" (or "BusID") option for each of the cards
to be initialized?
No. You could, but we use one Layout with the Xinerama mode. So we start only one X server that controls all four cards, arranging them as if they were one desktop with multiple screens. In this case, X initializes all cards.

Following are the "Device" sections from my xorg.conf.
I appreciate your assistance. This has been an awful
problem, Yitzhak

You should make your xorg.conf.probe with the layout described at our howto and use the same device section you sent me. Then, on the xorg.conf, you change the device section by putting
Option "UseInt10Module" "off"
since the cards were already initialized.

And please let me know of your tests. We also want NVidia cards to work properly.
