How to force re-config of xorg?

["s. keeling" <keeling@nucleus.com>]

I've run into this before, but can't find the answer again (it's
buried by *buntu forum cruft).  With "dpkg-reconfigure xserver-xorg" I
get:

  xserver-xorg postinst warning: overwriting possibly-customised
  configuration

And it just kicks me out.  How to over-ride that?  I promise to write
it down this time.  This is Sidux, AMD64.
