xfce4-notifyd 音量变化不再弹出通知气泡

大约一周以来，我在调整音量或插入耳机时会错过通知气泡。我正在使用纯 xfce4-session 运行 ubuntu bionic，这意味着元包 xubuntu-desktop 不在我的系统上。

    dbus-monitor --session interface='org.freedesktop.Notifications'
    signal time=1565429537.386265 sender=org.freedesktop.DBus -> destination=:1.73 serial=2 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameAcquired
       string ":1.73"
    signal time=1565429537.386395 sender=org.freedesktop.DBus -> destination=:1.73 serial=4 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameLost
string ":1.73"

插入耳机或输入命令后没有列出任何内容

pactl set-sink-volume 0 100%

发送后 notify-send test

      dict entry(

         variant             byte 1
      )
   ]
   int32 -1

我看不到任何错误。

注意声音效果很好，其他通知（如 guake）也正常工作。

抱歉，文字太多了。

编辑，pulseaudio-plugin 已配置，如果音量改变则发送通知。

我的系统上没有软件包 xfce4-volumed。

  apt list --installed | egrep 'volumed|pulseaudio|pavucontrol'

pulseaudio 是为用户会话配置的。

ps -ef | grep pulse

P：S 错误不在 /home 中。Testuser 和 guest-session 相同。

答案1

抱歉，我发现了。我正在使用 i3。元包将 dunst 带到我的系统上。清除该包并重新启动后，pulseaution 的通知已修复systemd[9580]: dunst.service: Two services allocated for the same bus name org.freedesktop.Notifications, refusing operation。

我在日记里发现了这一点，这让我走上了正确的道路
