The feature you want can't be implemented in the WM -- it is a
limitation of the X architecture. Since non-Xinerama heads are distinct
screens (:0.0, :0.1, :0.2), it is the app who determines which screen to
place window on. And there's a reason for it: separate screens may have
different parameters (depth), so one can't easily "move" e.g. a 24bpp
window to 8bpp screen.
So, if you want to open two browser windows on two screens, the
*browser* must support this. (AFAIK, Emacs knows how to open a window on
different display).
As to just multiscreen-capable WMs, all TWM derivatives are OK --
TWM, fvwm/fvwm2, WindowMaker, AfterStep (but the latter had some stupid
problems in Wharf). I've looked into Gnome and KDE about a year ago --
that time they were incredibly stupid and simply ignored screens other
than :0.0. We use fvwm2 2.4 in our lab on 4-headed PCs, and we are happy
-- it is both multiscreen- and Xinerama-aware.
BTW, you wrote "I guess most people use Xinerama. I would gladly
use it if I could specify which screens to bind together.". What do you
mean by that? Is it about relative placement of screens (completely
doable), or do you need to join only some screens into Xinerama, while
leaving others as separate :0.x's (not likely to be ever implemented,
according to Mark V.)?
