That is mostly what I could do with FreeBSD and "hardware
mechanisms":
1. - trivial, worked out of the box
2. - worked when Fn+PF7 (I think, look at the key captions) was
pressed, so the laptop's display got vertical black bars
to arrange 1024x768 (which the initial external monitor had)
3. - I have tried something similar with a Lenovo laptop and a
docking station, so X could somehow manage "two displays",
just if a PCI GPU had a VGA and a DVI connector
4. - again, "hardware", when the internal display was switched
off, the (new) external display's size was properly detected
Nothing really required specific support in software, not as
a specific driver or the ability to change a setting inside a
desktop environment. I know that a lot of this can experimentally
be achieved with the xrandr tool, the rest can be "hard-coded"
if needed in xorg.conf's successor.

I think #3 is a feature of X's multi-display support, such as
the ability to have two separate screens, or just "concatenate
them" (vertically or horizontally) into one logical screen; I
think this is called the "Xinerama" extension - it's years ago
that I experimented with this. :-)
