Disabling Keyboard Shortcuts didn't work in Ubuntu

I'm a working with eclipse in Ubuntu. In eclipse, i frequently use a shortcut "Ctrl + Alt + Down Arrow" to duplicate the current line. I found that Ubuntu also has the same shortcut to switch the workspaces. So, my problem is when I press "Ctrl + Alt + Down Arrow", it calls the system's action. I tried this by disabling the keyboard shortcut in Ubuntu too. Still, it didn't work for me. Can anyone help me on this problem ?

In Ubuntu 18.04 do the following:

  1. Enter the Settings -> Devices -> Keyboard.
  2. In 'Navigation' menu click on the 'Move to workspace below' definition.
  3. Click on 'Backspace' to delete ALL current shortcuts, and then click on 'Set' above.
  4. Click again on the 'Move to workspace below' and press your desired shortcut (i.e. Super + Page Down) and then 'Set' above.

Now 'Ctrl Alt Down' is available, enjoy!

In my case I am running ubuntu 17.10 + Gnome, inside the keyboard shortcut configuration UI I was only seeing one binding

Move to workspace above : Super + Page Up
Move to workspace below : Super + Page Down

But in fact there was 2 shortcuts defined on those actions, as you can see with the following command

> gsettings get org.gnome.desktop.wm.keybindings switch-to-workspace-up
['<Super>Page_Up', '<Control><Alt>Up']

So I simply re-bound the shortcut inside the UI to Super + Page Up, it erased the second binding

> gsettings get org.gnome.desktop.wm.keybindings switch-to-workspace-up
['<Super>Page_Up']

In my case with Ubuntu 18.04 changing the setting in UI was not reflected in gsettings get... I achieved desired change with the same gsetting tool. First, check current setting:

 $ gsettings get org.gnome.desktop.wm.keybindings switch-to-workspace-down
['<Super>Page_Down', '<Control><Alt>Down']

Then set new setting (note that setting needs to be quoted):

$ gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-down  "['<Super>Page_Down']"

Then check new setting:

$ gsettings get org.gnome.desktop.wm.keybindings switch-to-workspace-down
['<Super>Page_Down']

System Settings > Keyboard > Shortcuts > Navigation > Switch to workspace above

System Settings > Keyboard > Shortcuts > Navigation > Switch to workspace below

System Settings > Keyboard > Shortcuts > Launchers > Key To Show The HUD

Disable or reassign these

Lubuntu uses Openbox. System bindings can be found in ~/.config/openbox/lubuntu-rc.xml. Search it for <keybind key="C-A-Down"> and <keybind key="C-A-Up">.

I am used to Ctrl + Alt + Down shortcut and CompizConfigSettingsManager method didn't work for me.

But I found solution in my Ubuntu Studio 14.04 (XFCE):

  • Open Windows Manager: xfwm4-settings
  • Go to Keyboard tab
  • Scroll down to Lower worskpace Action
  • Hit Clear button

Copy line shortcut works fine in Eclipse now.

1st solution: Remapping binding in eclipse

Have you tried remapping the binding in the preferences?

Window -> Preferences -> General -> Keys

Type "copy lines" in the filter.

Select the entry and edit the binding - I changed it to Ctrl+Alt+Numpad_4 and this seemed to work.

2nd solution: Disable keystroke in compiz

Note my actual fix for this is to disable a setting in compiz, but yo said this failed, here's what I did anyway in case it is useful:

System->Preferences-> ConpizConfigSettingsManager

Click "Advanced Search"

Type "down" in the filter box.

Click on "Desktop wall"

Disable "Move Down".
