Bug#926920: Additinal reports

[hoxp18 <hoxp18@noramail.jp>]

Dear maintainers,

* LibreOffice AppArmor profiles needs some more rules,
  by aa-logprof check.

  w/ or w/o that tuning, LibreOffice seems and works normally.

* ibus-mozc Japanese Input seems fine.

  I can compose Japanese article with it, by LibreOffice Writer.

  At Stretch, Tools and Properties are sometimes unavailable;
  though I can not reproduce them and have no idea what is wrong.

* sshd works.

* PAM su restriction, securetty works.
  I setup them to restrict direct tty root login only; no sudo.

* HDMI connected speakers does not play sounds.
  GNOME setting panels' speaker tests does not work, too.
  (GeForce 1030 -> HDMI -> LCD w/ speakers)

  I have no idea about these problems survey,
  If you have any idea what I should check and/or attempt,
  please give me your idea or some instruction.

  I'm testing on dedicated machine.
  I almost can do anything including HW configurations.

Regards.
