It's both, kinda. Twinview provides xinerama extensions so that it can tell 
the window manager where everything is. However, if gnome doesn't start up 
with the xinerama (whether built-in to X or provided by Twinview) extensions 
being activated, it will never realise when they turn on. On the other hand, 
if gnome is started with the xinerama extension, it'll be happy about adding 
and removing external monitors, and so forth, all on the fly.

If you turn xinerama on in xorg.conf, then twinview can't use its xinerama 
extention to tell the WM what's happening (according to nvidia's docs, I 
haven't tried it)

The stuff you learn when things break, eh? :)

Yeah, that's similar to what I have - however, I have to use nvidia-settings 
to do it, as this is my laptop, and I regularly connect it to three different 
external monitors (work, home, uni) in different configurations. So writing 
the settings into xorg.conf isn't really an option.

BTW, now that all my show-stopper issues have been fixed (I had problems 
making wireless, sound, suspend and this screen thing work - all fixed now 
(the first three in one fell swoop: install the extra modules)), I have to 
say my initial impressions of gutsy are fairly good. Things are a bit tidier 
and newer. Nothing revolutionary that I've found so far, though.
