I am running a GNOME 3 fallback desktop in Debian testing, and I removed some pulseaudio packages, for I don't need the advanced functionality. That resulted in my multimedia keys that control speaker volume to work no more. This forces me to use a mouse on the classic volume control applet to control the volume, which isn't always convenient.

Here's what I get:

$ acpi_listen
button/volumedown VOLDN 00000080 00000000 K
button/volumeup VOLUP 00000080 00000000 K

note: the other Fn keys (brightness, suspend, ...) work okay

Are you using acpi? If, so run acpi_listen + keypress and edit /etc/acpi/handler.sh accordingly to run raise/lower scripts on these events (e.g. I'm using amixer set Master unmute 3%+ -q to raise volume). –  Herman Torjussen Jan 13 '12 at 16:24
What should I put in that file? –  Tshepang Jan 13 '12 at 17:25
This wiki site will give you all the information needed to setup. –  Herman Torjussen Jan 13 '12 at 17:53
BTW, Debian doesn't have that specific script, so am not even sure it would work. Also the output from acpi_listen is different from the wiki. –  Tshepang Jan 15 '12 at 10:26
