某天突然发现公司的笔记本声音特别大，自己又没跑什么程序，就很好奇。

打开top一看，发现一个有一个线程叫 tracker-store，cpu占用超过100%，把它kill掉后果然电脑就没那么大声音了。但过了一会，这厮马上又复活了，杀了好几次就是杀不死。

原来，这厮有自启动能力，可以自动复活！

然后解决它：

cd /etc/xdg/autostart

将tracker-extract.desktop，tracker-miner-fs.desktop，tracker-store.desktop三个文件删除即可。

但是这个办法对我来说居然没用。。。

禁止tracker-*软件启动

通过修改/etc/xdg/autostart目录下的tracker-开头的快捷方式（.desktop文件）

sudo sed -i "s/X-GNOME-Autostart-enabled=true/X-GNOME-Autostart-enabled=false/g" /etc/xdg/autostart/tracker-*.desktop
tracker reset --hard

就这一个命令电脑瞬间就安静了，牛的！

(base) lyn@l00 sudo sed -i "s/X-GNOME-Autostart-enabled=true/X-GNOME-Autostart-enabled=false/g" /etc/xdg/autostart/tracker-*.desktop
sed: can't read /etc/xdg/autostart/tracker-*.desktop: No such file or directory
(base) lyn@l00 tracker reset --hard

另外，在~/.config/autostart 文件中似乎也可以设置，但我没有设置。
