Logitech K270 has media keys:

  • play/pause
  • mute/unmute
  • volume down
  • volume up
  • home
  • mail
  • power
  • calculator

I don't know what "home" is supposed to do, whereas "mail" and "calculator" don't do anything simply (I hope I'm not wrong) because I haven't installed a calculator and a mail client yet.

But: "mute/unmute" only mutes.

As a workaround I've tried to put the following two lines

"pactl set-sink-mute 0 toggle"

in the .xbindkeysrc file, but the key kept muting the audio, so I mapped

"playerctl previous"

and it still kept muting, just like the mapping I'm using is overridden or simply not working.

Finally, as a dirty workaround I've used the following two lines

"pactl set-sink-mute 0 toggle"
  shift + XF86AudioMute

which works, but requires one more keystroke.

I've tried with other keys, and it seems that xbindkeys cannot map media keys without a modifier (ordinary keys work just fine even without).


By the way, I think I'm pretty confused on the argument (audio). For instance, system volume is a think, the volume set in the player is another. How to control the former? And the latter? What if I bind the same key to both?


When I run xbindkeys -n in a terminal, I get

$ xbindkeys -n

*** Warning ***
Please verify that there is not another program running
which captures one of the keys captured by xbindkeys.
It seems that there is a conflict, and xbindkeys can't
grab all the keys defined in its configuration file.

As it turns out, I was wrong in saying that play/pause and volume up/down keys were working since the beginning, I just forgot having put the following lines in ~/.config/i3/config

bindsym XF86AudioRaiseVolume exec amixer -q set Master 5%+ unmute
bindsym XF86AudioLowerVolume exec amixer -q set Master 5%- unmute
bindsym XF86AudioPlay exec playerctl play-pause
bindsym XF86AudioMute exec amixer -q set Master mute

where the last line is wrong, and was overriding the .xbindkeysrc setting.

Now I have to decide wether to put all settings in the i3 config file or in xbindkeys's file.

In either case the above solves my original issue.
