No, it's not g-s-d, but X that is setting it to mirrored in this case.
>From the Xorg.0.log, after correctly detecting all the resolutions:
[ 16.904] (II) intel(0): Using fuzzy aspect match for initial modes
[ 16.904] (II) intel(0): Output LVDS1 using initial mode 1024x768
[ 16.904] (II) intel(0): Output VGA1 using initial mode 1024x768
This is the standard default behavior that X.org provides, so is not an
X bug. Policy is handled at the gnome-settings-daemon layer, so g-s-d
*should* be putting your monitors into the extended configuration by
default as per the referenced multi-monitor design specification. X.org
does not track power or lid open/closed status so probably couldn't make
correct decisions anyway.
Unfortunately a large amount of what's in the specification is the
correct design yet simply hasn't been implemented, and that includes
this use case. Thus I think this is probably best carried as a wishlist
bug for gnome-settings-daemon.
Theoretically we could simply hack X.org to do extended by default (this
was experimented with briefly back when RANDR was first introduced).
The problem arises that in certain circumstances (e.g. projectors),
defaulting to extended can lead to confusing and undesired behaviors; in
fact there was discussion at some point by the design team to make
mirrored the default again, but I don't know the status on that.
Anyway, if/when this does get implemented, it will probably be too
invasive of a change to consider backporting, so the precise and quantal
tasks will have to be wontfix. For raring, we have a defined focus for
development which excludes development work for multimonitor, so I'll
target this bug to S.
