gvfs-udisks2-volume-monitor.service这个服务无法启动。一直提示org.gnome.desktop.lockdown这里不包含这个键值mount-removable-storage-devices-as-read-only

然后我就去找这个键值，然后就出现了神奇的事情，普通用户下没有这个键值，加上sudo就有这个键值。在root用户下也是。

如果我查看了/usr/share/glib-2.0/schemas/org.gnome.desktop.lockdown.gschema.xml,也有这个键值。

所以万能的坛友我该怎么办，说实话以前我并没有关注过这个服务是不是正常，只是最近更新之后，我在chrome浏览器点击上传会使浏览器卡住，才关注这个问题。卡住的时候也是提示这个服务没启动，没启动的原因也是缺失这个键值。
