Since when doesn't Fedora use xorg.conf ?

[Linuxguy123]

There are all sorts of posts associated with the "Disabling mouse taps
on Fedora 10" thread that state that Fedora 10 doesn't use an xorg.conf
file.

When did Fedora/X stop using an xorg.conf file ?

It certainly isn't mentioned in the F10 release notes.
http://docs.fedoraproject.org/release-notes/f10/en_US/What_is_New_for_Installation_and_Live_Images.html#X_Window_system_-_graphics

How and where are the X system settings set and held now ?

Thanks
