How do I disable Ctrl-Alt-D in gnome-shell?
I figured out that the following worked in my case. First, instead of trying to disable the shortcut, give it a new key combination. I did this in System Settings -> Keyboard Layout -> Layouts -> Options..., but it's a known bug that these settings are not respected in Gnome Shell.
Additionally, use dconf-editor to give it the same key combination:
- Open dconf-editor (Alt-F2, enter
dconf-editor) - Expand until the element:
org → gnome → desktop → wm → keybindings. - Change the value for the correct key (in your case, this should be
show-desktop).
In my case, I wanted C-M-s be respected in Emacs, and not roll up the current window. So instead of trying to disable the shortcut by using brackets in dconf-editor, I gave toggle-shaded a new key combination: ['<Control><Super>s']. And suddenly, C-M-s was available in Emacs. Hope this helps for you, too.
To disable the keybinding with gsettings, just use the value ['disabled']:
gsettings set org.gnome.desktop.wm.keybindings toggle-shaded "['disabled']"
I just hit this problem on Ubuntu 12.04 LTS trying to unset the Ctrl+Alt+S binding for "toggle-shaded". AFAIK, I'm running the out-of-the-box window config: GNOME3, Compiz, Metacity, Unity.
Both Compiz and Metacity bind Ctrl+Alt+S, which REALLY threw me because I kept trying to edit the keybinding for compiz as a number of posts indicate (or rather org.gnome.desktop.wm.keybindings). But this changed nothing that I could see, even after restarting X.
In frustration I tried to edit the Metacity keybindings, which succeeded immediately (no need to restart unity, compiz or X.) Here's the command line:
gconftool-2 --unset /apps/metacity/window_keybindings/toggle_shaded
Check $HOME/.gconf/apps/metacity/window_keybindings/%gconf.xml for the changes.
I monitored changes to all files in my $HOME via man:find while trying the various config editors: gnome-control-center, ccsm, dconf-editor, gconftool-2 to see what changed.
dconf-editor worked well for compiz. My understanding is compiz and metacity work together to render the display but I don't know how. And I think there are a number of pluggable window managers that work with compiz, so that may further complicate the issue.
