Bug#576454: Synaptics configuration lost by upgrade

retitle 576454 Synaptics configuration lost by upgrade
thanks

It turns out that the driver is working, it is just that my
configuration (that sets up things like multitouch and click-drag) in
the xorg.conf file is being ignored.

Something is wrong about that, but I'm not quite sure what.  Please take
your pick:

  1. there's no warning at upgrade time that the configuration will be
     ignored; or
  2. the configuration is not automatically rewritten to the new ways; or
  3. things are changing for no good reason; or
  4. the default configuration is bad.

Julien, what is the new way to configure the touchpad?
