[warning: probably ot] 'Virtual' xinerama support in Xfwm4?

[Don Christensen]

First, sorry to all for the top-posting in my earlier response.
Force of habit from work where I feel compelled to "conform" to
all the Windows-users.

Twinview is, as you say, like Xinerama, so again, emulating it on
a single display is redundant.

Does Twinview allow you to maximize on a per-monitor basis?  It's
been a while since I used Xinerama, and I've never used Twinview.
My understanding is that the window manager is not even aware of
the presence of two monitors, but I could be wrong on that.

Even if that is the case, I wouldn't believe that you could switch
virtual desktops independently on each monitor (real or virtual).
What would happen if you had a window spanning both monitors and
switched the virtual desktop on one of them?

Just get a big monitor if it has enough resolution.  Use the "maximize
vertically" function and then enlarge the window horizontally as much
as you need.  If you're using Twinview already, this seems like it
does everything you're currently doing, without the space in between.

Personally, I like the two 20" 1600x1200 LCDs I have, running as
independent displays.  Even if I could find a 3200x1200 or larger
single display (actually, I think IBM made/makes one), it would
be more expensive than the two I have.  But you have to figure out
what's most important to you--raw resolution or physical size.
