I can't seem to get the nvidia driver to work without being in twinview.

Xorg.0.log shows final error message that screens are sharing mem 7 io resources.

As soon as I enable twinview the problem goes away.

This is a problem for me as my desktop configuration is quad head (two monitors on two quadro cards)

This was working with an older driver before the system was "rootkit" hacked and I needed to rebuild it from scratch.

Distro F7 kernel 2.6.22.9-91.fc7
NVidia 96.43.01
Quadro 280

Have you tried running nvidia-settings? I find that works really well for me (admittedly just with two monitors and one card).

Yes. It is odd that when I use nvidia-settings and turn off twinview i get the error. You'd think it was tested. I it would probably fail with just one quadro and two monitors in non-twinview mode.

It also doesn't have rotation as a choice. I want (had) all four screens rotated so I could see more lines of text.

For now I have a super-wide screen (5120x1024).

Thanks.

Solved.

Option "Rotate" "CCW"
Option "TwinViewOrientation" "Above"

Now I have my four rotated monitors (4096x1280)
