If you know what you need, adding a separate conf file
in /etc/X11/xorg.conf.d/ is the cleanest way to go. If you need some
type of custom setup, however, you can generate an xorg.conf using "Xorg
-configure". The X server must not be running when you do this.

## Go to run level 3

init 3

## Generate xorg.conf

Xorg -configure

## The configuration file will be stored in "root" user's home (/root)

"init 5" to test. You can test your changes by jumping in and out of run
level 5.

     When  this option is specified, the Xorg server loads all video
driver modules, probes for available hardware, and  writes  out an
initial xorg.conf(5) file based on what was detected.  This option
currently has some problems on some  platforms,  but  in most  cases  it
is  a  good way to bootstrap the configuration process.  This option is
only available when the server is  run as root (i.e, with real-uid 0).
