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.
