ATI Radeon dual head problem with Xorg-7.3.1

[Richard Jones]

Hi,

I've just upgraded from Xorg-6.9 to Xorg-7.3.1 and my dual head
configuration no longer works.

I've tried a variety of settings from man 4 radeon all of which have the
same effect - a cloned dual head.

Can anyone help? Attached is my old working config.

Cheers,

Richard
