I have been able to finally get a big desktop dual monitor set up using
the proprietary fglrx driver but it was not very easy or clear cut how
to do so.

 I eventually had to disable randr in /etc/X11/xorg.conf with the
following option added in the "Driver" section.

Options "EnableRandR12" "false"

Then I was able to use aticonfig to set a big desktop.

Before doing that, there was no way to get dual monitors to work as a
big desktop in KDE/Jaunty with any driver. With randr enabled all the
options to set a big desktop with aticonfig or the Catalyst Control
Center fail with messages about randr being incompatible with xinerama.

I suspect that I would also be able to disable randr and use xinerama to
acheive a big desktop with the Radeon driver but I have not tried that.
