Well. Here's a funny thing. I was going mad last night trying all kinds of xorg options. On many occasions I'd get a black desktop after login - unity was dying. If I did get unity started then changing resolution would corrupt the display as reported in the bug. However I could login and change resolution as any other user. Other clues like getting the "welcome to dropbox" dialog on login led me to realise it was something broken with my profile.
I then started systematically moving/removing config from ~/.config/ and couldn't figure out what was breaking it. So I went on a bit of a rampage and removed all of ~/.config/nautilus and ~/.config/dconf. This "fixed" the problem. I can now login fine, and more importantly can change resolution, all with no changes to my xorg.conf (which I'd already reverted).
