我在 Dell Inpiron 5567 上运行 Bullseye 和 XFCE。
我在这个系统上有两个用户：我的和来宾；每当我从首先登录的帐户注销并再次登录时，[b]即使作为我的用户[/b]，pulseaudio也不会自动启动，除了“注销”之外，所有其他选项都xfce4-session-logout变得不可用；我附加了一个链接到此屏幕截图（当尝试将图像上传到此帖子时，我收到“内部服务器错误 500”）。在图像中，您可以看到当我运行xfce4-session-logout以及音频混合器尝试连接到 Pulseaudio 时发生的情况；这是在我的主用户重新登录后发生的。
我担心的不仅仅是当我以访客用户身份登录时才会发生这种情况，而且当我注销并以主用户身份重新登录时也会发生这种情况。当然，这一切都不会发生在 CLI 模式下。
这是 cat /var/log/auth.log 的输出，因为我不知道还能去哪里查看才能知道发生了什么。
