Title:
  unity actively overrides system-wide gsettings as current user, making
  some vendor overrides ineffective

Status in Unity:
  New
Status in unity package in Ubuntu:
  New

Bug description:
  How to reproduce:
  as root execute
  # echo -e "[org.gnome.desktop.input-sources]\nsources=[('xkb', 'us'), ('xkb', 'hu')]\n\n" >> /usr/share/glib-2.0/schemas/99_my.gschema.override
  # echo -e "[org.compiz.unityshell]\nlauncher-minimize-window=true\n\n" >> /usr/share/glib-2.0/schemas/99_my.gschema.override
  # glib-compile-schemas /usr/share/glib-2.0/schemas
  and, either remove contents of home directory or create a new user,
  and, reboot and log in as the appropriate user.

  Result is that launcher-minimize-window settings=true as expected and
  launcher behaves accordingly, however input sources is just [('xkb',
  'us')], where as it should be [('xkb', 'us'), ('xkb', 'hu')].

  The launcher-minimize-window is just a random example. For most
  settings the vendor override method works.

  But for a few, like "org.gnome.desktop.input-sources sources", they
  will not take effect, as some process, related to Unity, will override
  them for the current user after login.

  Proof of this, is that running `gsettings reset org.gnome.desktop
  .input-sources sources` will result in [('xkb', 'us'), ('xkb', 'hu')],
  and the panel offering both layouts. Hence the vendor-override-method
  of setting system-wide defaults does work, but Unity ruins it for a
  few settings.

  The proof that this bug is in Unity is that, installing another
  desktop environment, like gnome-shell, and logging into it, leaves all
  the system-wide defaults effective.

  This bug makes vendor overrides, that should affect all "fresh" user
  accounts, ineffective.

  The appropriate behaviour would be that a new user, or one that has
  its home directory cleared, to have the system-wide default gsettings
  in effect for their unity session.

  Original problem statement: http://askubuntu.com/questions/582083
  /what-is-overriding-the-systemwide-keyboard-layout-settings

  To get a more comprehensive but still incomplete listing of the settings that Unity overrides, log in into a "fresh" Unity session,
  $ gsettings list-recursively >/tmp/01
  $ gsettings list-schemas | xargs -n 1 gsettings reset-recursively
  $ gsettings list-recursively >/tmp/02
  $ diff /tmp/0* | less
  This listing is incomplete, because it only lists non-relocatable schemas, and also because your system-wide defaults may match those of what Unity sets the users settings to. For example, not changing the layout setting to "[('xkb', 'us'), ('xkb', 'hu')]" with a vendor override, would cause it not to be listed.
