I would like to set and retrieve the custom keyboard shortcuts via commandline. I've found out how to set and restore the normal standard shortcuts using gconftool-2 (and navigatable via gconf-editor). I've also seen that apparently custom keyboard shortcuts are stored in dconf, though I'm skeptical.

In attempting to use dconf to write and read the settings, it doesn't seem like the tool is updating the same setting. Can anyone help me find and update these custom keyboard shortcuts?

What I tried in dconf:

  1. I set the shortcut:

    dconf write '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0' "'<Primary><Alt>p'"

  2. I checked by opening up the unity dash, and going to 'keyboard' and 'keyboard shortcuts'. It didn't seem to be set.
  3. Then I set my own shutcut on "custom0" to see if I used the wrong syntax. I set and cleared several times and called:

    dconf read '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0'

  4. Even though other keyboard shortcuts are set, custom0 was the only one that returned values.

Context: I'm trying to swap between pianobar and banshee multi-media keys. I found out about pianobar ctl's socket used for sending keyboard shortcuts. I switch between sometimes and it's tedious to open up the keyboard shortcuts each time to update them. I've already figured out how to set the multimedia keys via:

gconftool-2 --set '/apps/gnome_settings_daemon/keybindings/play' --type 'string' '<Primary><Alt>p'
gconftool-2 --set '/apps/gnome_settings_daemon/keybindings/play' --type 'string' ''

Edit (2014-12-18):

I wonder if I'm going about this wrong. It doesn't seem like keyboard -> shortcuts has many commandline options.

CCSM also handles capturing keyboard shortcuts, is that at all configurable via commandline?


Note related, but not duplicate questions:

  • For what it's worth, I've started doing something else here to solve my problem: gist.github.com/isaaclw/cbd3bf7bb13f5aefe987#file-multimedia-sh I check for the program that's running and then run a specific qdbus command to start/stop the program instead of worrying about swapping key-bindings. – isaaclw Oct 31 '16 at 19:29
  • I could post it as an answer, but it's not really an answer to my specific question. It's just a different approach that others might find useful. – isaaclw Oct 31 '16 at 19:30

To show all:

gsettings list-recursively  | grep --ignore-case "keys\|hotkey\|keybind"

To get:

gsettings get org.gnome.settings-daemon.plugins.media-keys calculator

To set:

gsettings set org.gnome.settings-daemon.plugins.media-keys calculator 'Hiragana'

For more info:

man gsettings

To easily get the values for "special" keys (multimedia, non-standard function keys):

xev | grep -A2 --line-buffered '^KeyRelease' | sed -n '/keycode /s/^.*keycode \([0-9]*\).* (.*, \(.*\)).*$/\1 \2/p'

All these are standard in any recent Ubuntu; no need to install any additional tools.

  • Thanks for the help, this seems to be pointing a helpful direction, but I'm stumped again. I currently have a keybinding set: "<Ctrl><Alt>p" which is running /usr/local/bin/pianobar-ctl p I know it because it's happening. But I don't see any reference to it in gsettings list-recursively so I'll need some other tool I guess to toggle that setting. – isaaclw Dec 17 '14 at 21:32
  • Actually looks like gsettings just loops back to dconf (which doesn't seem to work. gsettings list-recursively | grep custom0 sends me to /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0 which is what I tried to set with dconf, and didn't seem to have any effect. – isaaclw Dec 17 '14 at 21:39
  • dconf uses the underlying gsettings, not the other way around. And gsettings will allow you to enter things you can not necessarily do in dconf. So in your particular case, you need to gsettings list-recursively | grep --ignore-case "alt+p\|alt>p" and then remove all the [Alt][P] stuff that you find and then assign it to your custom shortcut. If you post the output of the above command, I'll help you a bit further. – Fabby Dec 17 '14 at 21:49
