Ok I downloaded and installed the appropriate driver from AMD: md5: 7c7b82f0d87a7ce9ee816b7d77212faa amd-driver-installer-12-3-x86.x86_64.run sha1: f62146ed5653ce81dca578e0252c7f32d55627be amd-driver-installer-12-3-x86.x86_64.run
I've since discovered that this is not the recommended way to do things on ubuntu, so acting on your advice I removed this with the uninstall shell script in the /usr/share/ati folder. I then tried to install the update fglrx package from jockey. This failed, log attached in next comment (it will be the first of two installs in that log file.) I then just on a whim tried the regular non-update fglrx from the jockey UI. It worked. I rebooted. No error. I changed to dual displays again, rebooted a few more times, still no error. So from my point of view this is resolved. Why it got messed up when installing from the amd installer, I have no idea, or why the update driver couldn't be installed from jockey I don't know.
