gnome-settings-daemon does not display notification bubbles on volume changes

[Adrian Roman]

Binary package hint: gnome-settings-daemon

According to a discussion with Matthew Paul Thomas, when changing the volume from a script, gnome-settings-daemon should display the corresponding notification bubble.

The script I am using relies on amixer to change the volume. It is called by irexec when lirc detects the volume buttons keypresses on the remote control. Here's an example script:

adyroman@panther:~$ cat lirc_scripts/volume_up.sh
#!/bin/bash
/usr/bin/amixer -c 0 set Master 10%+
adyroman@panther:~$

I am using Ubuntu 9.04 AMD64:

adyroman@panther:~$ lsb_release -rd
Description: Ubuntu 9.04
Release: 9.04
adyroman@panther:~$ apt-cache policy gnome-settings-daemon

Per the discussion with Matthew, Mirco should be the correct assignee for this bug report.

This is still a problem in Karmic. There are no notifications for volume changes done through amixer.

How do you suggest to implement this in g-s-d? Currently, it handles the keypresses, changes the volume and displays the notification. If you want it to display the notification when it notices the volume has been changed, then it would also display when adjusting the slider in the volume applet, which would be absolutely horrendous.

The only way I can think of, would be for g-s-d to export some D-Bus methods for changing the volume, which you would then have to adjust your scripts to use

[Adrian Roman (adyroman5)]

I have to admit I haven't figured out what the most appropriate way of
dealing with this is, but from a usability point of view it seems natural
that any change of the volume that is not caused by the volume slider should
be presented in a notification bubble. As far as I am concerned, if there's
any way to do this from a script, it's just fine with me - I don't _have to_
use amixer - any scripted way to change the volume and present a
notification bubble is fine by me.

Does this have to be handled at the g-s-d level? It may be easier to leave it up to whatever is interacting with g-s-d to handle notifications. I don't know anything about the architecture of amixer, but couldn't it just be patched to interact with notify-osd?
