当我将闪存驱动器插入 PC（Ubuntu 20.04.2 LTS）时，它不会自动挂载。我必须打开磁盘工具并手动安装驱动器。自动挂载设置已启用：
$ gsettings list-recursively org.gnome.desktop.media-handling
org.gnome.desktop.media-handling autorun-never false
org.gnome.desktop.media-handling autorun-x-content-open-folder @as []
org.gnome.desktop.media-handling automount-open true
org.gnome.desktop.media-handling autorun-x-content-ignore @as []
org.gnome.desktop.media-handling automount true
org.gnome.desktop.media-handling autorun-x-content-start-app ['x-content/unix-software']
创建 fstab 条目对我来说不是一个好的解决方案，因为我还想自动挂载新设备。
肯定是某个地方的某个东西被禁用了，但我不知道在哪里。如果有人知道，请告诉我 :-)
journalctl -xe更新：根据评论中的要求，这是连接 USB 设备后的日志。

此外，权限似乎是正确的：
getfacl /media/<username>
# file: media/<username>
# owner: root
# group: root
user::rwx
user:<username>:r-x
