NVidia 190.42 + Tripple head setup with Xinerama = Crash


Question: What do I need to do to get Xinerama running ok with my
quad head setup?

After installing Fedora 12, the Nvidia 190.42 proprietary driver
enabling compiz, everything looked ok:

Dual head setup + xinerama = OK

The next step was to enable my third and fourth screen. Using the nvidia-settings manager I created a working setup (separate X screens)

Quad head setup + no xinerama (separate X screens) = OK

The final step was to enable xinerama in my working X configuration,
but after enabling xinerama sometimes the login window appears but
after that the complete system hangs and needs a reset.

Quad head setup + xinerama = Crash


What am I doing wrong ?



For info, here is my quad head working xorg.conf
(with Xinerama disabled)
