I dont think you're being very clear.
You seem to be saying you want the features of xinerama, but not use
xinerama.
If you want to move windows between heads, then you want xinerama.
If you want the features listed in the xinerama faq, then you want
xinerama.
Why do you say you do not want xinerama?
I see you emphasised the word *single* above. It make no difference
whether you have a single dual-headed card or two separate video cards.
You would be able to use xinerama with both setups. Perhaps that is
causing you confusion.
If you already have a working XF86Config-4 setup with two heads as
separate screens (:0.0 and :0.1), you should simply be able to add
Option "Xinerama" "true"
to you ServerLayout section.
It is then a matter of whether or not your applications recognise
xinerama (if they need to). I am not familiar with the window manager
you mentioned in your previous mail, so I dont know how well that
supports xinerama.
Unfortunately, some applications are not xinerama aware and they do
something like get the size of the root window, calculate the middle and
explicitly place a window at that position. This ends up being on both
monitors. I dont know if a xinerama-aware window manager can do anything
about this. ssh-add(1) had this problem. I dont know if it has been
fixed, but it was enough for me not to use xinerama - particularly since
I have no real need to move windows between screens.
I think you just need to experiment a little and make sure the apps you
want to run will work well with xinerama. For most, it wont matter. For
others, they'll be xinerama-aware and behave according to the guidelines
in the FAQ you referenced. Others will not.
I run a dual-headed matrox card (G400), but I dont use xinerama.
