Bug Description
When booting with an external monitor attached, the external monitor shows a stretched-out display, which the laptop monitor shows two black bars on each side of a lesser-resolution GDM display. This problem persists after logging in and is illustrated by these pictures:
GDM display:
https:/
In-session display:
https:/
It's rather common to boot with the screen connected, so the use case for this really is problematic as the Ubuntu splash doesn't look right when a workstation is started like this. I happen to be in an environment where everyone runs Windows and cosmetic details like this really undermine confidence in Ubuntu.
This was also tested with a 11.10 nightly 3 weeks ago. I have to use the monitors utility every-time the system is rebooted to adjust resolutions.

Hey magicfab,
You filed this bug report against natty, but I see it's still open and
doesn't appear to have much activity recently. So, now that oneiric
is released and stable, this may be a good point for you to upgrade
and re-test if this issue is still present there.
If it's solved in the new release and you think it's worth backporting
the fix, please indicate that. Or if having the fix in the new release
is good enough, feel free to close out the bug (or let us know and we'll
close it.)
If it's not solved, leave the bug report open. I can't promise we'll
get to it (we get way more bugs filed than we can usually get to), but
your testing and feedback can help out if and when we do.
