在 Fedora 屏幕锁定上运行脚本

发布于 2024-12-21 17:16:00 字数 554 浏览 1 评论 0原文

我正在寻找一种在 Fedora 15 (linux) 中锁定屏幕时运行程序的方法。基本上我想在屏幕锁定时开始运行运动检测程序，或者我手动按 Ctrl+Alt+L，但我不'不知道正在运行哪些命令或在哪里为我自己的中间步骤添加别名。我认为是：

gnome-screensaver-command --lock

但不知道如何解决这个问题。有人知道如何做，或者开始寻找的方向吗？

编辑，因为链接位于评论中：这是通过 dbus-monitor 完成的，并在此处进行了描述。

I'm looking for a way to run a program when locking the screen in Fedora 15 (linux). Basically I want to start running a motion detection program when the screen locks, or I manually hit Ctrl+Alt+L, but I don't know what commands are being run or where to alias my own intermediate step in. I assume it's:

gnome-screensaver-command --lock

but am not sure how to go about this. Anybody know how, or a direction to start looking in?

Edit, since link was in a comment:
This is done with dbus-monitor and described here.

dbus 系统通告屏幕锁定；监视 org.gnome.ScreenSaver 上的 ActiveChanged。（请参阅 http://people.gnome.org/~mccann /gnome-screensaver/docs/gnome-screensaver.html ）

例如（为清楚起见，自动换行）

    signal sender=:1.68 -> dest=(null destination) 
           serial=53 path=/org/gnome/ScreenSaver; 
           interface=org.gnome.ScreenSaver; member=ActiveChanged
        boolean true

不幸的是，恐怕这需要编写更多的代码，而不仅仅是 shell 脚本；尽管我很好奇您是否可以要求 dbus 以某种方式调用您的程序作为该信号的处理程序；否则，我想你只需启动一个守护进程并监听要广播的信号......

The dbus system advertises screen locking; monitor for ActiveChanged on org.gnome.ScreenSaver. (see http://people.gnome.org/~mccann/gnome-screensaver/docs/gnome-screensaver.html )

e.g. (word-wrapped for clarity)

    signal sender=:1.68 -> dest=(null destination) 
           serial=53 path=/org/gnome/ScreenSaver; 
           interface=org.gnome.ScreenSaver; member=ActiveChanged
        boolean true

Unfortunately, this will require writing more code than just a shell script, I'm afraid; although I'd be curious if you could ask dbus to call your program as a handler for that signal, somehow; otherwise, I suppose you'd just start a daemon process and listen for that signal to be broadcast…
