Multimedia keys refering to X display. A bug of acpid?

Davigetto · 2007-09-17 14:08:02

Hello, I have a really strange problem. I am setting up the Multimedia Keys of my laptop, editing the /etc/acpi/handler.sh file. I have tested all the multimedia keys when I restart the acpid daemon on a xterm terminal, and all keys work perfectly.

But when I boot my pc, and I try to use the multimedia keys, graphical applications (like kazehakase webbrowser and audacious on my example) don't work. But terminal applications and commands, like mute, volume up/down, wireless, Touchpad... all of them works correctly.

To make them working I must do "/etc/rc.d/acpid restart" on a graphical console (yes, I must a graphical console like xterm or Eterm, if I do it in a Ctrl + Alt + 1 console, for example, it doesn't work). When I do it, all multimedia keys works correctly, but I found really painful and uncomprehensible all of that.

What's the matter? What can I do to make all graphical applications runned by a multimedia key without restarting acpid? Maybe a bug?

I join my /etc/acpi/handler.sh. Focus on hotkey part.
