我最近将工作站从 Debian 9 升级到了 Debian 10。使用旧版本，人们已经能够安装 USB 驱动器并播放和录制声音（用于视频会议）。更新后两者都不起作用。

远程用户帐户

用户帐户存在一些特殊性，因此这可能是问题的根源。我们使用 NIS 和 NFS 在所有机器上提供用户帐户和主目录。升级到 Debian 10 后，我需要添加一个NISto，/etc/nsswitch.conf因为它们compat之前是打开的，现在只有files. 也ypbind没有运行，因为它不再用作 -broadcast默认启动选项。我在以下位置添加了一个新的 systemd 文件 /etc/systemd/system/ypbind.service：

[Unit]
Description=ypbind
Wants=network-online.target nis.service
After=network-online.target nis.service

[Service]
Type=simple
ExecStart=/usr/sbin/ypbind -broadcast -foreground

[Install]
WantedBy=multi-user.target

这样用户帐户就在那里，主目录也在那里。在命令行上我也可以登录。但是 LightDM 显示管理器仍然不允许用户进入。所以在/etc/lightdm/lightdm.conf部分中[LightDM] 我添加了该选项greeter-show-manual-login = True，从那时起远程用户可以登录。有些机器仍然将 GDM 作为默认设置显示管理器，登录显示与 LightDM 在我更改配置之前所做的相同行为。密码检查通过，屏幕可能会短暂变黑，然后再次显示登录屏幕。当用户超出其配额并且.Xauthority无法创建建立会话 (?) 所需的文件时，也会发生同样的情况。

奇怪的是，当我通过 SSH 登录并在实际屏幕上登录时，这些会话正确显示为who：

$ who
ueding   pts/0        2019-08-26 12:42 (131.220.226.20)
ueding   tty7         2019-08-26 12:43 (:0)

但同时会话未列出loginctl：

$ loginctl
No sessions.

当我使用本地用户帐户在我的个人 Fedora 30 笔记本电脑上执行相同操作时，我得到以下输出who：

$ who
mu       tty1         2019-08-25 10:33 (:0)
mu       pts/0        2019-08-25 10:34 (:0)
mu       pts/1        2019-08-26 12:08 (:0)
mu       pts/2        2019-08-26 12:14 (:0)
mu       pts/3        2019-08-26 12:42 (:0)
mu       pts/4        2019-08-26 12:38 (:0)
mu       pts/5        2019-08-26 12:55 (:0)

并且还loginctl显示了一些明智的东西：

$ loginctl
SESSION  UID USER SEAT  TTY
      1 1000 mu   seat0    

1 sessions listed.

我在其中一个 Debian 10 工作站上创建了一个 UID 为 50000 的新本地用户帐户，发现我可以登录，显示会话，loginctl并且下面描述的可移动媒体和声音问题不存在，声音和可移动媒体作品。所以这绝对是来自 NIS 的用户的问题。

到目前为止，让我印象深刻的一件事是，由于历史原因，我们给出的用户 ID 以 500 开头。但我的用户ueding的 uid 为 1085，所以即使这是未列出帐户的问题，这account 应该没问题，因为不被视为系统用户的用户 ID 的默认起始值​​为 1000。

我没有足够的经验，但我只是觉得不知何故用户帐户没有完全在系统中，只是仍然缺少一些东西。

一位 uid 为 536 的用户在登录后必须输入他的 GNOME 钥匙串密码。我不确定他那里是否有不同的密码，但也可能是在启动过程中没有解锁。不过，这可能并不意味着什么。

授权日志

在当前状态下，这是/var/log/auth.log自启动机器以来显示的所有内容，通过 SSH 以 root 身份连接以检索日志并使用我的 NIS 用户登录机器本身。此外，monitoring用户已通过 SSH 登录以检索我的监控系统的一些信息。

目前的结论

我觉得有些东西会阻止用户“完全登录”，从某种意义上说，他们确实有 Xfce 会话并且可以看到他们的主目录，但不足以注册“花哨”的东西，比如 logindPulse Audio . 或者他们可能缺少一个特殊的用户组。机器上的本地用户帐户按预期工作，因此这肯定是一般用户帐户的一些问题，而不是症状之一（loginctl输出、声音、可移动媒体）。

我无法真正掌握这一点，我不确定我应该在哪里看。非常欢迎指针或（希望）解决方案！
