Default Problems with KDE & Flash after moving to dual adapter

Hi,
I'm wondering what experience (and hopefully guidance) others can
provide to hopefully fix these new problems on my compute server.
Thanks in advance.

OK, yesterday I added a second NVidia adapter to my machine and
used nvidia-settings to create a new xorg.conf file. (Both new and old
are shown at the end) The new setup came up easily and I now have 3
monitors. Here's the setup:

GTX 465 port 0 -> GPU-0 + DFP-0
GTX 465 port 1 -> GPU-0 + DFP-2

8400GS port 0 -> GPU-1 + CRT-1

To get this working I had to enable the xinerama use flag as well
as enable Xinerama in xorg.conf.

Some simple tests of functionality:

1) glxgears is functional on all 3 displays but only draws actual
graphics on the two GTX465 monitors. It draws a black window on the
8400GS. It is my understanding that this is expected.

2) Both Virtualbox and VMWare VM's work fine on all 3 monitors. If the
VMs are running Windows then Flash, Java & Silverlight seem to work
fine on any display. I can play NetFlix movies and run other Windows
apps from within the VMs without any major problems so far.

Problems:

1) Adobe flash within Linux is not working at some websites, such as:

http://www.jigsawdoku.com/

For this page the flash game area is just gray. Flash does however
seem to work on other sites like Adobe's web site so possibly this is
more an issue with that page but I've seen a couple of others so far
that do the same thing.


2) Two KDE features that I like quite a lot are not working at all:

a) F8 - display all desktops doesn't work. With the original 2
monitors the feature worked fine.

b) The upper left corner 'display all apps' feature is not working.

I've been Googling around without any luck in terms of finding
things to try in terms of fixing this, or even discovering that maybe
these things simply don't work with two adapters. Maybe there are some
accelerations or features I need to enable that nvidia-settings don't
do for me? I don't know.

Note that in the older 2 monitor configuration I was using Twinview
which treats the two monitors as a single large monitor.

Thanks in advance for any ideas about how to get this working at its best.

Cheers,
Mark
