[已解决]openbox如何才能使用KDE下Alt+F2的命令输入功能

桌面环境
1

在 KDE 下按 Alt+F2，屏幕上方会有个快捷命令输入栏，openbox 如何才能使用这个功能? 我目前是 KDE 和 openbox 都有安装。登录时选的是 openbox 而非 openbox-KDE。

好像不行耶，在 openbox 下直接运行 krunner 都不行呢，会出现如下错误：

Object::connect: No such signal org::freedesktop::UPower::DeviceAdded(QDBusObjectPath)
Object::connect: No such signal org::freedesktop::UPower::DeviceRemoved(QDBusObjectPath)

这个是 Krunner

可能要启动 KDE 才能用。因为现在 Krunner 好像是整合在 Plasma Desktop 里面的。

可以找个别的 Runner 用。

4

不知道 GNOME Do 能不能在 Openbox 里面用？

或者什么其他的？

5

KDE 有跑 qdbus 的。krunner 不是平台独立程序。

6

在 ~/.config/openbox/rc.xml 里面的 下面加上这些内容

    <keybind key="A-F2">
      <action name="Execute">
        <execute>krunner</execute>
        <startupnotify>
          <enabled>true</enabled>
          <name>krunner</name>
        </startupnotify>
      </action>
    </keybind>

这样就能让它运行 Krunner。不过每次登入 openbox 以后，第一次用 krunner 会没反应。如果用命令行会有以下内容。

➜  ~  krunner

然后系统会自己开 4 个 kde 的进程，之后才能正常使用 Krunner。
