I’m having an issue with the volume_brightness.sh script. I’m using i3wm and when I use my volume keys to adjust the volume, I’m not getting the notification from dunst that I usually do. However, the volume IS getting adjusted. I looked up the bindsym for the volume keys in ~/.config/i3/config and saw that it was using a script to display the volume changed using dunst. So, I ran the script in a terminal “~/.config/i3/scripts/volume_brightness.sh volume_up” and this was the output:
Use the button indicated below to format the script’s content properly for easier reading. Just select all of the content, then press the button or press CTRL+E instead.

Thank you. That did work. This script was part of the default setup, though. Like, it was there as part of the fresh install I did when I first switched to Endeavour, and it did work for a long time. Should I file a bug report or something?
I do have one more question though. Using notify-send appears to add an extra volume icon. I see that there is a way to specify which icon to send with notify-send, is there a way to tell it not to send an icon at all? I’d prefer to just stick with the in-line icon since the script sets it dynamically by the volume level. Is there a way to tell notify-send not to include it’s icon? That would be more in line with how the notification appeared originally too.
I used the second one. I toyed around with it while I was waiting on a reply, though, and figured out that it would accept null as an argument for the -i option and just added that and it worked. Thank you though.
