Indeed, I don't think we can rely anymore on the fedora pyxf86config
for the long term. It seems to be deprecated as system-config-display.

Here is the very basic xorg.conf file needed by the nvidia driver:
Section "Device"
        Identifier  "Videocard0"
        Driver      "nvidia"

Then I've successfully tested that the ModulePath section could go to

Section "Files"
        ModulePath   "/usr/lib64/xorg/modules/extensions/nvidia"
        ModulePath   "/usr/lib64/xorg/modules"

rpmfusion-config-display is also affected by the crash, so we need to
redesign it anyway.

The drawback is that we become more and more static. We will also not
be alble to fallback to another driver in the case of a missing nvidia
But I think that feature was already broken and it's now even more
broken with the f14 crash of livna-config-display. So it would be
better for livna-config-display to be removed at all. So users can
have a working configuration on install without having it broken
afterward because of that crash.
