Description of problem:

I just installed current rawhide which I believe is the same as FC2 test3.

In firstboot, I changed my display properties from "thousands" to
"millions" of colors.

It appears as if that created (or possibly modified) the file
/etc/X11/XF86Config since I now have two files /etc/X11/XF86Config and
/etc/X11/xorg.conf and the XF86Config has the 'millions' of colors
setting.
