That sounds odd, you should have to work quite hard to get X to output
an interlaced signal. Perhaps it's just outputting something your TV
*thinks* is 1080i? Can you please post the X logs somewhere so we can
see?

Well, you can run X -configure , but it doesn't really give you exactly
that. It just gives you a very basic xorg.conf with the driver
specified. I can't think of a particular reason you'd need an xorg.conf
which exactly reflected the current auto-detected configuration (and
it'd be rather long as it'd have to codify all the RandR stuff). If you
just add whatever configuration *change* you need to the basic xorg.conf
you can get by doing X -configure, it should work as you'd expect.

See https://fedoraproject.org/wiki/How_to_create_xorg.conf .

I don't really know if there's anything like this.

That's a bug, please report it on Bugzilla.
