When you miss xorg.conf as a configuration tool

Now most drivers are administered with udev the xorg.conf is not default present in your install anymore.
Still you can get your xorg.conf back for instance if udev can't work for you in getting the correct driver to work or you cannot set the screen resolution you want.

You have to add hal as a daemon in rc.conf
Notice this when doing so:
Edit as root /etc/rc.conf
especially the last daemon line
Make sure you DON'T have dbus in your daemons line if you have hal in it. I stopped dbus by putting an exclamation mark before it: !dbus
hal will start dbus as well.
