gsettings全局设置所在位置：
/usr/share/glib-2.0/schemas/
cache位置：
/home/socol/.config/dconf/user
通过追踪power设定来确定cache所在位置：
1. power的gsettings全局设定在
/usr/share/glib-2.0/schemas/org.gnome.settings-daemon.plugins.power.gschema.xml
2. 通过命令监控gsettings改变,并且进入control center手动改变power设定：
[socol@localhost Downloads]$ gsettings monitor org.gnome.settings-daemon.plugins.power
sleep-inactive-ac: true
sleep-inactive-ac: false
sleep-inactive-ac: true
3. 追踪监控程序读取的相关文件列表：
[socol@localhost Downloads]$ ps aux|grep gsettings
socol 19882 0.0 0.1 27036 2688 pts/2 Sl+ 19:26 0:00 gsettings monitor org.gnome.settings-daemon.plugins.power
socol 20283 0.0 0.0 4452 752 pts/1 S+ 19:28 0:00 grep --color=auto gsettings
[socol@localhost Downloads]$ lsof -p 19882

4. 移除/还原可疑文件，在移除/还原后确定control center中对应的结果是否匹配。
5. 确定gsettings的cache文件为：
/home/socol/.config/dconf/user
