心血来潮，给笔记本装了linux，版本是当下最火的mint。唔，使用体验不错～下面记录的是修改mint锁屏相关设置的修改方式。
In Linux Mint 13, the screen lock feature is disabled by default. After being idle for a while, the screen will be dimmed and you can re-activate it by moving the mouse or hit a key. For security reasons, you may want to enable the screen lock feature. Here is how to do it: Hit Alt + F2 and run "mateconf-editor" to open the Mate configuration window. Go to apps > mate-screensaver then check the line "lock_enabled". You can also edit the line idle_delay to change the minutes of inactivity time before the screen lock is activated.
在这里可以使能/取消lockscreen，修改锁屏时延等。
或者，直接打开应用screensaver修改也是可以的。
另外，如果想更换解锁界面的背景图片，可以到/usr/share/backgrounds/linuxmint目录下，修改这个软链接指向目标图片即可。
