I was wondering if you had set switch to screen instead of window to
screen, as when I was looking it up I saw the "switch..." first and /
almost/ got fooled by that myself, but then I saw the switch to desktop
functions along with the accels I'd set for them and realized it wasn't
what I (you) was (were) after.
But I decided I'd test it to be sure, and sure enough it worked for me.
However, /again/ I almost got fooled by the switch-to functions when
setting it up myself, which is why I specifically stated the path
including the window-to bit when I reported my success, hoping you'd
catch that, which you did. =:^)

It *IS* different, as I have it (partially, test/temporary) setup that
way now. Confirmed, all three work.
Now I just have to permanently mount the hardware, and reconfigure plasma
and superkaramba and all my kwin hard-positioning rules... which will
take some time and patience, but shouldn't be too terrible.

Yes. I'm familiar with those limitations from years ago, when I used to
run three monitors on two different cards myself. But as screen sizes
increased, eventually I decided two was sufficient, since the tradeoff
was OpenGL across both.
But now I have three outputs on the one card again, and I still had the
old 21-inch monitors after my upgrade to 42-inchers, so I thought I'd try
it and see. Sure enough, it works. =:^)
Meanwhile, I /think/ the native kernel/mesa/xorg radeon drivers along
with the graphics-arbitrator option (which I have off as I have only one
card anyway) are now able to handle multiple cards with full OpenGL as
well, at least if they are compatible drivers. However, I've not tried
it, and with three independent outputs per card and today's full-HD or
better resolution per monitor, with monitor/TV sizes as large as you care
to go, I doubt I'll have good reason to any time soon.

Yes, /that/ seems to work well, at least on current "best-FLOSS-support"
radeons, the hd-6xxx series, aka northern-islands.
What's nice is that unless you're a demanding 3D gamer and need the
newest hardware and want servantware drivers, the radeon FLOSS drivers
work best on a generation back, which ends up being a very nice price-
point, while not being so old the cards are hard to find and at a premium
again (as was the case the last time or two I upgraded my old AGP system
upgraded to dual-dual-cores with 8 gig RAM so it wasn't /too/ outdated
compute-power-wise, just bus-wise, before the mobo died with bulging/
leaked caps a bit after the 8-year point).
$100 buys a very nice mid-line radeon northern-islands "turks" hd6670
with a gig onboard RAM and three independent outputs. Actually, perhaps
a bit more, now, as that was about a year ago.

Well, you know what to get and what drivers to use for 3-output single-
card, anyway. =:^)
FWIW, the outputs on mine are one each, HDMI, DVI, and DisplayPort. The
two new monitors actually being 42-inch TVs, cheaper end ($400 each) for
LED-based, so only HDMI input, so to them I'm running one HDMI-HDMI, and
one DVI-HDMI, which was running from the HDMI out on the old card to the
DVI in on the old monitor, but is now "reversed", DVI out on the new card
to HDMI in on one of the TV/monitors. The old monitor is DVI and the
unused output on the card was DisplayPort, so I got a DisplayPort/DVI
adapter that I could plug one of the old DVI-DVI cables into.
So if you go that way, do be aware of the inputs and outputs you're going
to be running and what cables or adaptors you may need to do it.
FWIW, DVI, DisplayPort and HDMI are all three electronic signal
compatible, so a passive adapter is fine. My old netbook, however, only
had VGA out, which is of course analog, so to plug it into the (digital-
only) HDMI on the new TV/monitor, I had to buy an active adapter, a bit
But I like that old netbook and I actually just bought an SSD to replace
the hard drive with (the netbook's only SATA-2, but the SSD is SATA-3, so
when I do upgrade I can take it out of the old netbook and plug it
directly into whatever new I get, for full speed SATA-3), so the active
VGA/HDMI adapter was worth it. And I can keep updating it from the 32-
bit build-chroot on my main machine, and I topped it off to 1.5 gig RAM
as soon as I got it, so with the SSD, the old single-core hyperthreaded
1.6 GHz atom n270 CPU (IIRC, the first atom Intel sold, in any case)
should be fine for runtime use for some time yet. So getting the active
adapter was worth it. =:^)
Meanwhile, in addition to the DisplayPort/HDMI adapter, I got three SSDs,
one for the netbook (as mentioned), two for the main machine, all
upgrades from "spinning rust" (tho I'll keep the spinning rust for a
media drive on the main machine), so I have my work cut out for me doing
the upgrades and reconfigures over the next few days...
New toys to play with are always fun! =:^)
