Hey.
I'm using Fluxbox and I wonder if there is a simple lightweight daemon for handling volume change notifications (and possibly other notifications) ?. |

What I and most people do is a self-crafted script or something like that, and bind it to a key. I use something like this for setting the volume:
| Code: | #!/bin/bash -x
CHANNEL="Master"
vol=$(amixer sget "$CHANNEL" | grep "Mono: Playback" | sed -e "s/%.*//" | sed -e "s/.*\[//")
if [ $# -eq 0 ]; then
echo $vol
exit 0
fi
let vol=vol+$1
if [ $vol -gt 100 ]; then
vol=100;
elif [ $vol -lt 0 ]; then
vol=0;
fi
#echo $vol
amixer sset "$CHANNEL" $vol% > /dev/null
echo $vol
|
I do it this way because I need some fine grained control over the output (it's used for something else later, once the script is done). This receives an integer (as '1' or '-1', for example), and increases the volume by that amount. It's intended just as an example to give you a general idea (it won't probably work for you without some slight change(s)), you can use any other command line mixer application and you can also use some notifier plugin just as notify-send, kdialog, zenity, osd_cat or whatever people use these days to draw nice stuff on their screen (I can live without that).
The simplest solution would probably be to bind some command line mixer that can increase the volume in steps (or decrease it) via the fluxbox configuration file (I don't remember at all how keybindings are configure in fluxbox, but I assume the process is similar to this on pekwm, openbox, fvwm and most minimalist wm's.

I use a script as well, the only tricky thing was to get a proper notifications with the old notifications daemon. Of course notify-send will do, but every volume change will create new notification, so I use gdbus to create proper volume notification (they are replacing each other). The script is below:
| Code: | #!/bin/sh
usage="usage: $0 -c {up|down|mute} [-i increment] [-m mixer]"
increment=1%
mixer=Master
uid_file="/tmp/volume_notify_${USER}"
if [ -f $uid_file ]; then
uid=`cat $uid_file`
else
uid=1
fi
while getopts i:m:h o
do case "$o" in
i) increment=$OPTARG;;
m) mixer=$OPTARG;;
h) echo "$usage"; exit 0;;
?) echo "$usage"; exit 0;;
esac
done
shift $(($OPTIND - 1))
command=$1
if [ "$command" = "" ]; then
echo "usage: $0 {up|down|mute} [increment]"
exit 0;
fi
display_volume=0
if [ "$command" = "up" ]; then
display_volume=$(amixer set $mixer $increment+ unmute | grep -m 1 "%]" | cut -d "[" -f2|cut -d "%" -f1)
fi
if [ "$command" = "down" ]; then
display_volume=$(amixer set $mixer $increment- unmute | grep -m 1 "%]" | cut -d "[" -f2|cut -d "%" -f1)
fi
icon_name=""
if [ "$command" = "mute" ]; then
if amixer get Master | grep "\[on\]"; then
display_volume=0
icon_name="audio-volume-muted"
amixer set $mixer mute
else
display_volume=$(amixer set $mixer unmute | grep -m 1 "%]" | cut -d "[" -f2|cut -d "%" -f1)
fi
fi
if [ "$icon_name" = "" ]; then
if [ "$display_volume" = "0" ]; then
icon_name="audio-volume-min"
else
if [ "$display_volume" -lt "33" ]; then
icon_name="audio-volume-low"
else
if [ "$display_volume" -lt "67" ]; then
icon_name="audio-volume-medium"
else
icon_name="audio-volume-high"
fi
fi
fi
fi
gdbus call --session --dest org.freedesktop.Notifications \
--object-path /org/freedesktop/Notifications \
--method org.freedesktop.Notifications.Notify \
Volume $uid $icon_name "" "<b>Volume: ${display_volume}%</b>" \[\] {} 5000 \
| sed -r 's/\(uint32 (.+)\,\)/\1/' > $uid_file
