Description:

Impulse is a bit of eye-candy for your desktop. It is a widget that displays a graphical spectrum analyzer on your gnome desktop. It is written in c and python and uses GTK and cairo graphics to generate the animation. the impulse library creates a pulse audio connection context that reads the output stream from pulseaudio in a thread natively which can then be read from python. You can specify impulse to either output the raw stream or output the fft of the raw stream.


Requires:
screenlets 1.2
libfftw3-3
libpulse0


Install:
1) Download and extract Impulse.tar.bz2
2) mv Impulse ~/.screenlets/
then open up the screenlets manager and start Impulse or open screenlets manager and click Install, navigate to the Impulse.tar.bz2 archive and click ok.

I've got a problem with Impulse. The screenlets is well drawn but it's not moving ! I've got an message when i execute it via terminal :
CachingBackend: Loading instances from cache
CachingBackend: Loading <Impulse1>
Found a running session of Impulse, adding new instance by service.
Error in screenlets.services.get_service_by_name: org.freedesktop.DBus.Error.ServiceUnknown: The name org.screenlets.Impulse was not provided by any .service files
Screenlet has already been added to /tmp/screenlets/screenlets.guizmos123.running

and this one too :
Impulse/ImpulseScreenlet.py:66: DeprecationWarning: integer argument expected, got float
self.window.resize( w * self.scale, h * self.scale )

Hey guizmos, what version of screenlets are you using? I am using 0.1.2. I googled Error in screenlets.services.get_service_by_name and it seemed to come from older screenlets versions.

Does the screenlet install? When you try and run it can you see it but it doesn't move or do you see nothing? Do you see any errors if you run it from a terminal?

It runs fine, I can see the red bars above the blue bars. I can move it around. I CANNOT right-click on it, however, when the config/close button shows up in the top right corner of the screenlet I can edit the options.

How do I run it from the terminal?

Oh ok, Connection failure: Connection refused means that in the cimpulse module the PulseAudio context that was created failed to connect. Could you send me the output of "pactl list" for me. Its going to be long so it might be best to send me a private message.

That is strange. Is PulseAudio set up correctly and running on your machine? What distro are you using?

Well I'm using Ubuntu Intrepid. I did some tweaking to pulse a while back, but I think I disabled those. In any case, any ideas why this would be happening? I'll be re-installing once Jaunty comes out so may look into it then.

This has to be the best widget I have ever seen so far... stretch it out at the bottom of the screen and it works perfectly and look excellently.

So, it does work you just can't change it, right? If this is the case then there is probably no problem. Screenlets have this problem where you cannot click on semi-transparent pixels. Just really try and click on it, it will take a few times but you should get it. If you really still can't then let me know.
