ah, ok, I didn't realize you had setup dualhead. As Julian noted,
fluxbox doesn't support geometry updates.

You might want to try a newer X server. I think older ones may have
not properly dealt with preferred modes on more than 1 output.

That seems reasonable, but when you consider that the default mode is
clone, what do you do if each monitor has wildly different preferred
modes? You'll end up with areas that are only visible on one monitor
or the other. The current situation is a mess.

Both of those options are for debugging. I'd rather have users report
the problems and fix the bugs for real than to just enable the option
and never mention it.

I've added a quirk to the driver that should remove the extra DVI port:
