How to disable global -p shortcut?

Question

In ubuntu 11.04 there was a workaround using gconf-editor and setting key /apps/gnome_settings_daemon/plugins/xrandr/active to false.

However there is no such key in gconf-manager using ubuntu 11.10 (gnome 3).

Answer 1

On Ubuntu 18.04, I found two different keybindings for SUPER+P, which can be disabled with dconf-editor.

First, you need to install dconf-editor, if it's not already installed. This can be done in the terminal with the following command:

sudo apt install dconf-editor

Then you can launch it from the terminal:

dconf-editor

Within dconf-editor:

• Navigate to: /org/gnome/mutter/keybindings/switch-monitor
• If the "Custom value" field contains ['<Super>p', 'XF86Display'], then:
  • Disable "Use default value"
  • In the "Custom value" field, type the following: []
• Navigate to: /org/gnome/settings-daemon/plugins/media-keys/video-out
• If the "Custom value" field contains '<Super>p', then:
  • Disable "Use default value"
  • In the "Custom value" field, delete everything.

Here's how to disable it with gsettings from your terminal

gsettings set org.gnome.mutter.keybindings switch-monitor "[]"

If you want to restore the shortcut

gsettings set org.gnome.mutter.keybindings switch-monitor "['<Super>p']"

Answer 3

The new version of gnome-settings-daemon stores its configuration information in dconf rather than gconf.

To do the equivalent of what you were doing on 11.04, try the following:

1. Install the dconf-tools package, and then run dconf-editor.
2. In the tree on the left, navigate org -> gnome -> settings-daemon -> plugins -> xrandr.
3. Uncheck the active checkbox.

Answer 4

In order to disable global <Super>p keybindings, and NOT any other media keys (tested in Ubuntu 15.04) I had to 'emtpy' the following dconf keys. I ran (in a terminal):

dconf write /org/gnome/settings-daemon/plugins/media-keys/video-out ''
dconf write /org/gnome/settings-daemon/plugins/media-keys/screenshot ''

Before, I searched with the next bash commands for values that contained '<Super>p':

b="/org/gnome/settings-daemon/plugins/media-keys/"
for i in `dconf list $b | sort`; do echo -n "$i: "; dconf read $b$i; done

To search all dconf keys, use the command:

dconf dump / | grep '<Super>p'

If you want to avoid the terminal, run the program dconf-editor and search for the key(s) there...

Edit:

After some upgrades and restarts, I had the keybinding not working any more. I found, that there is/was a bug in gnome-settings-daemon that defines <Super>p. A hack is described here.

In the startup process, /usr/bin/xbindkeys_autostart is executed on login. This script searches for the file in $HOME/.xbindkeysrc and loads the settings.

Since I wanted to map gnome-screenshot -c to <Super>p, I created the this file with the following content (and unmapped the settings in ubuntu/compiz):

# Content of $HOME/.xbindkeysrc
"gnome-screenshot -c"
mod4 + p

This is still an issue as of Ubuntu 12.10 released October 18, 2012. A bug fix for this seemed to be in the works so that at least there is an easier way to re-configure the key bindings, but it has since been marked invalid because this was supposedly fixed in gnome-settings-daemon.

Ultimately this problem is supposedly due to some hardware vendors hard-coding video out to Super-P.

There have been updated conversations on the bug tracker since the currently-accepted answer that suggest not turning off xrandr, but instead turning off media-keys:

Try the following:

1. Install the dconf-tools package, and then run dconf-editor.
2. In the tree on the left, navigate org -> gnome -> settings-daemon -> plugins -> media-keys.
3. Uncheck the active checkbox.

Or the command-line version of this is:

dconf write /org/gnome/settings-daemon/plugins/media-keys/active false

Answer 6

Even if disabling the xrandr plugin isn't working for you (like me), I suggest you to try this (it works for me):

Go in the dconf-editor via the command "dconf-editor" in a terminal, then go at:

/org/gnome/mutter/keybindings/switch-monitor

and disable "use default value" and delete:

'<Super>p',
