Debian: ログアウトするとサービスが利用できなくなる

Dell Inpiron 5567でBullseyeとXFCEを実行しています。

このシステムには、私のユーザーとゲストという2人のユーザーがいます。まず、ログインしたアカウントからログアウトして再度ログインするたびに[b]マイユーザーが[/b]あっても、pulseaudioは「ログアウト」以外の場合を除いて自動的には起動されません。 "、他のすべてのオプションは利用できなくなります。このスクリーンショットにリンクを添付しました（この投稿に画像をxfce4-session-logoutアップロードしようとすると"内部サーバーエラー500"が発生します）。xfce4-session-logoutすると、何が起こるのかがわかります。これは、デフォルトのユーザーが再度ログインした後に発生します。

懸念されるのは、ゲストユーザーとしてログインするときだけでなく、ログアウトしてからマスターユーザーとして再ログインするときにもこの現象が発生することです。もちろん、CLIモードではこれは起こりません。

これはcat /var/log/auth.logの出力です。何が起こっているのかを調べるために、他の場所を見つける必要があるのか​​分からないからです。
