Here are the relevant parts of my xorg.conf for a cloned setup with an

#-----------------------------------------------------------------------
This allows me to run
startx -- -layout Cloned
to start X with the cloned display, and
startx -- -layout Default
for the normal display (external output off). If you only want the
cloned display then you can remove the normal "Device", "Screen" and
"ServerLayout" sections, of course.
To avoid confusion due to my earlier statement about the two "Device"
sections in the OP's xorg.conf: Yes, I do have two such sections as
well, but in my case only one is used at any given time, depending on
the ServerLayout.
This xorg.conf works very well for me, but I actually prefer to use a
normal (not cloned) xorg.conf and to switch the external output on/off
with the i810switch tools. (I do not have to restart X for the change to
take effect in that case.)
I never had any reason to play around with Xinerama, therefore I do not
have a configuration ready for that case.
