谢谢反馈 ，是不是 开启了自动挂载  取消试试

已经是取消的状态了，还是不行。。。。。

蛮奇怪的案例。。。我这里一切正常，ntfs也是默认挂载。

~/.config/deepin/dde-file-manager
这个是文管的配置，把它备份一下，然后删掉，看看文管能不能启动。

那直接mv不就得了

话是这么说。不过为了体现“备份”的重要性，还得强调一下。

你的文件管理器打开目录中　是不是有 后缀为.desktop文件, 如果有，把这些desktop全部移走试试，如果成功了，就是这些desktop文件内容解析有问题导致的

感谢各位，以上方法试过之后，崩溃现象没有了，但我不太确定是怎么解决的，(⊙﹏⊙)b
