DVD/蓝光驱动器不显示任何磁盘内容

DVD/蓝光驱动器不显示任何磁盘内容

我在一台旧游戏机上运行 Ubuntu 18.04.3 LTS 服务器版本。

最终目标是拥有一个无头 DVD 翻录器。

所有三个驱动器均可见，并响应弹出命令。

> ls -ltrFa /dev/sr* brw-rw---- 1 root cdrom 11, 0 Jan 27 03:18 /dev/sr0 brw-rw---- 1 root cdrom 11, 2 Jan 27 03:18 /dev/sr2 brw-rw---- 1 root cdrom 11, 1 Jan 27 04:00 /dev/sr1

但不知何故，每次我将 DVD 插入任何驱动器时，/mnt/dev/sr[0-2] 中都看不到任何数据，也没有任何 udev 脚本运行

到目前为止我唯一的线索是来自 dmesg 的输出

阅读一些论坛帖子后我尝试了这个（虽然我不确定它们有何关联）：

sudo apt remove       libdvd-pkg  handbrake-cli  
sudo apt install vlc  handbrake-cli libdvd-pkg libdvdcss-dev libdvdcss2 -y
sudo dpkg-reconfigure libdvd-pkg

这对我来说确实很奇怪

我也有同样的情况，但仅限于一些商业 DVD。我尝试看的最后一部是 APOLLO69（汤姆汉克斯的阿波罗 13 号故事）。这个问题与驱动器无关。这是一个 UDEV 错误，与 UDEV 子系统尝试解密/读取 DVD 并失败的方式有关。在这些尝试期间，驱动器被重置多次，内核陷入 I/O 状态，最后您必须重新启动系统才能解决问题。似乎已提交错误报告但因时间太长而关闭。
经过大量的谷歌搜索，我找到了一种解决方法，即使 DVD 图标未显示在 Nautilus 文件管理器中，也可以实际使用驱动器中的 DVD。请参阅此帖子https://forum.makemkv.com/forum/viewtopic.php?f=3&t=25357 当然，如果是使用 CSS 保护的商业 DVD，您将必须获取密钥并告诉驱动器使用哪些密钥。
如果您想查看 DVD 中的文件，您必须启动 VLC 或其他 libcs​​s 应用程序来解密光盘，然后使用 sudo mount -o ro /dev/sr0 恢复到老式方法。我无法创建或填写错误报告给 UDEV 或内核团队，因此不会这样做，但我希望有一天这个 PITA 能够在没有这些奇怪的解决方法的情况下得到解决。希望这能有所帮助。
