环境
系统：Debian GUN/Linux 10, bullseye
桌面：Xfce 4.14
问题描述
本来Xfce的默认文件管理器是Thunar，有一次偶然尝试了一下Nautilus作为默认文件管理器。结果发现开机进入桌面后系统反应变慢，查了一下发现是一个进程tracker-miner-fs占用了100 %的CPU。关于这个现象网上已有多处讨论，仅举一例：
查了一下它的出处，原来它是Nautilus的依赖包：
> apt-cache depends nautilus

看了处理方法比较复杂，索性卸载了Nautilus，再没有这玩意的干扰。不过Nautilus是Gnome桌面的默认文件管理器，不能这样一卸了之，各位Gnome桌友要小心了。
参考它的手册知道，它的启动在用户登录后启动了.desktop快捷方式，该文件在：
~/.config/autostart/tracker-miner-fs.desktop
我想可以删除这件文件，以避免它的自动运行。不过这只是猜测，我没有尝试。
