xorg.conf missing? [duplicate]

Question

im using the closed nvidia driver: i think my xorg.config is missing:

ls in the directory /etc/X11 shows:

app-defaults             rgb.txt             Xreset      Xsession.d
cursors                  xinit               Xreset.d    Xsession.options
default-display-manager  xkb                 Xresources  xsm
fonts                    xorg.conf.failsafe  Xsession    Xwrapper.config

is this normal? i would like to edit the file with this: http://www.phoronix.com/scan.php?px=MTY1OTM&page=news_item

Current ubuntu distributions (i guess since 10.04) don't ship with an X config file any more.

If you even interested in having a xorg.conf, you can find here some useful help.
