How can I bring up a dialogue window when a usb device plugged?

How can I bring up a dialogue window when a usb device plugged?

[Andy Chen]

Hi There,

I need someone kind help on config udev module for auto pop up dialogue window when device plugged via the rule define.
Here is simple rules I defined but not working. Can someone point out what should be for the proper setting:

ACTION="add", SUBSYSTEM="usb", ATTR{idVendor}="04b4", ATTR{idProduct}="1004", RUN+="Xdialog --title "INFO BOX"& "

Thanks advice for your feedback,
Andy

This will not work as you do not have a x session from this context.

Try writing a program that either ties into libudev to catch these kinds
of events, or uses dbus to watch for HAL events.  Then you can create
your own dialog box when specific devices show up as you wish.

Hope this helps,

Hi Greg,
 
Thanks for the advice.
 
For the mechanism you mentioned, does it mean that I should create a daemon with libudev to keep on tracking the event coming out and bringing the gui window from there?
Is it the method employed in current kernel for the file explore auto pop up when usb hard drive plug in?

 
Thanks,
Andy

Yes.

The kernel does no such thing, that is up to the desktop infrastructure.
I think Gnome uses HAL and dbus to do this currently, KDE uses much the
same thing as well.  I suggest you go look at their code if you have
questions.

good luck,
