That's why I said "not quite" - I could see where you were heading...

You're right - it doesn't always work.  I had, on gutsy, a dual-screen setup
that worked fine, upgraded to Hardy and got an auto-configured Xorg.conf
that didn't work, dropped in the old one, and it didn't _quite_ work
either - there was still some playing around to make it work properly. 
Then I upgraded to Kubuntu 8.10, and dual-screens became completely

Using your previously working xorg.conf is ime usually a better starting
point when the auto-configuration doesn't work at all, but it's certainly
not guaranteed.
