To be really sad and the only one to reply to my own post ;) I've got it
working. I tried using grandr to see if I could find out what was going on, but
that has nothing to do with anything and wouldn't run. Then I rebooted with the
dual screens configured as a mirror. This enabled the option in the AMD
configuration to work with the second screen, although I could still do nothing
to configure the Xinerama settings, however after running:
amdconfig -- initial=dual-head
from the CLI and rebooting (again) I could enable Xinerama (initially when I
moved the mouse onto the second screen it went all retro X on my with the
chunky X cursor!). Once that was enabled, and after another reboot, I was
working nicely - bar the fact that the screens were on the wrong side of each
other. Since there was no configuration option for this I simply swapped the
cables (I suspect if I manually edited the xorg.conf file I could have swapped
them by changing the ServerLayout section).
Not exactly easy, but I thought I'd post in case anyone else was stuck.
