可以终止，没一会儿又开始了。

知道我為毛不用那東西沒？

LXDE更简单(组成简单意味着故障率低)
针对楼主的问题,试试看用软链接之类重定向到zram之类的内存块设备上?
不过是治标不治本的方法

如果终止没问题的话,试试看直接把这个程序文件删了?

vickycq 写了： dconf-service 写磁盘 ~1.5MiB/s 持续不断

请问你是怎么追踪到是这个程序在读写磁盘的呢？我有时候也有莫名的程序在读写磁盘，但是我不知道怎么找出来。

桌面放了conky，监视 CPU、I/O 占用率最高的进程。但 I/O 监视不准确。
事实上 I/O 高的进程 CPU 占用也会排在前列。

学到了iotop这个命令，话说我的conky只有CPU占用前五的进程，但是经常是一些kworker/0:3这样不明所以的进程～
谢谢啦～
