xorg.conf in Fedora 10

Fedora 10 has no /etc/X11/xorg.conf by default. The X setup is detected automatically. If this is not the case your display might remain black or is somehow disturbed.
In this case it can be useful to create a tiny /etc/X11/xorg.conf (which will be used if present).
This configuration will use the default vesa driver and should work always although the resolution and the refresh rate might not fit your needs and still need to be configured properly.
