Thanks for reassigning this report to xserver-xorg package. After some google search i came to know that xorg.conf file is managed by xserver-xorg package.
>I am also changing the priority, as this is an improvement request.
I have found the xorg.conf manual page at command line itself. So i didn't visit the link you have given below. The manual pages for xorg.conf can be found by following command:
man xorg.conf
Thanks again.
