18.04 ctrl+shift to change language

Can I use Ctrl+Shift for changing languages? I can’t set this hotkey for changing keyboard languages.

At this moment Alt+Shift switch languages, but I can’t see this hotkey in keyboard hotkeys list or in

gsettings list-recursively  org.gnome.desktop.wm.keybindings | sort | more

output.

Here is Solutions:

We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.

Solution 1

You can set such keyboard shortcut as follows:

  • On Ubuntu 18.04 LTS, 20.04 LTS, 21.04 and 21.10 with GNOME desktop from GNOME Tweaks.

    1. Install it

      sudo apt-get install gnome-tweaks
      
    2. Then open GNOME Tweaks (gnome-tweaks).

    3. Select Keyboard & Mouse tab

    4. Click Additional Layout Options button

    5. Expand Switching to another layout

    6. Select Ctrl + Shift here

    See screenshot below:

    18.04 ctrl+shift to change language

    Or simply:

    gsettings set org.gnome.desktop.input-sources xkb-options \
      "['grp:ctrl_shift_toggle']"
    

    If you do not like Super + Space and Shift+Super+Space you can disable them with

    gsettings set org.gnome.desktop.wm.keybindings switch-input-source "['']"
    gsettings set org.gnome.desktop.wm.keybindings switch-input-source-backward  "['']"
    gsettings set org.freedesktop.ibus.general.hotkey triggers "['']"
    

    Note: you will face interference problem as Ctrl+Shift+T in GNOME Terminal will switch language at once with opening new tab. It is known bug 1683383.

  • On Ubuntu MATE 18.04 LTS and newer versions this is possible from mate-keyboard-properties:

    1. Open MATE Control Center
    2. Click Keyboard
    3. Go to Layouts tab
    4. Click Options
    5. Expand Switching to another layout
    6. Select Ctrl + Shift here

    See screenshot below:

    18.04 ctrl+shift to change language

    Or simply:

    gsettings set org.mate.peripherals-keyboard-xkb.kbd options \
          "['grp\tgrp:ctrl_shift_toggle']"
    

    Note: here bug 1683383 is fixed by packages from my PPA :

    sudo add-apt-repository ppa:nrbrtx/xorg-hotkeys
    sudo apt-get update
    sudo apt-get dist-upgrade
    

    So Ctrl + Shift keyboard layout switcher will work normally on MATE DE after applying patch from ArchLinux AUR "for freedesktop bug 865 (need to kick hotkeys on release, not press)".

    Warranty disclaimer: packages were tested in

    • 16.04 LTS with HWE (Unity, MATE, Xfce)
    • 18.04 LTS (Cinnamon, KDE, MATE, Xfce)
    • 18.10 (Cinnamon, KDE, MATE, Xfce)
    • 19.04 (Cinnamon, KDE, MATE, Unity, Xfce).
    • 19.10 (Cinnamon, KDE, MATE, Unity, Xfce)
    • 20.04 LTS (Cinnamon, KDE, MATE, Unity, Xfce)
    • 20.10 (Cinnamon, KDE, MATE, Unity, Xfce)
    • 21.04 (Cinnamon, KDE, MATE, Xfce)
    • 21.10 (Cinnamon, KDE, MATE, Xfce)

    However other desktops may have issues even after applying the patch.
    These packages do not fix problems for GNOME Shell (18.04 LTS, 18.10, 19.04, 19.10, 20.04 LTS, 20.10 and 21.04) and Unity (in 18.04 LTS and 18.10).

Solution 2

I found a partial workaround based on other answers for using Ctrl+Shift and shortcuts for GNOME in Ubuntu 18.04:

  1. Install GNOME Tweaks as proposed in N0rbert’s anwser:

    sudo apt install gnome-tweaks
    

    then:

    • run it;
    • open “Keyboard & Mouse” tab;
    • click “Additional Layout Options” button;
    • instead of selecting Ctrl+Shift key combination in “Switching to another layout” of “Additional Layout Options” window simply untick all checkboxes:

    Additional Layout Options

  2. Open “Settings” application from “Show applications” menu at the left bottom corner. Alternatively run a command in terminal:

    gnome-control-center
    

    then

    • go to “Devices” > “Keyboard” tab;
    • scroll to “Typing” group;
    • set shortcuts for “Switch to next input source” and “Switch to previous input source” (an order of keys DOES MATTER!!!):

    Keyboard settings

    If setting Ctrl+Shift or Shift+Ctrl shortcuts is impossible using this dialog (as it was in my case), then you can change these parameters in an alternative way:

    • install dconf-editor:

      sudo apt install dconf-editor
      
    • run it from terminal:

      dconf-editor
      
    • go to org > gnome > desktop > wm > keybindings;

    • select switch-input-source or switch-input-source-backward;
    • switch off “Use default value” and input “Custom Value”: <Control>Shift_L for changing layout with Ctrl+Shift or <Shift>Control_L — for changing layout with Shift+Ctrl:

    dconf-editor

    Another way is to use gsettings set console command as proposed here:

    gsettings set org.gnome.desktop.wm.keybindings \
    switch-input-source "['<Control>Shift_L']"
    

A limitation of this solution is that an order of keys pressed is important. If you set Ctrl+Shift to change keyboard layout then it will work only when you press Ctrl key first, and then Shift key. Pressing Shift key first and Ctrl after will not work in this case. But this fact allows to use shortcuts containing Shift and Ctrl keys combination in different applications , for example:

  • Shift+Ctrl+T to open new tab in Terminal;
  • Shift+Ctrl+E to export image in Gimp;
  • Shift+Ctrl+F to open search dialog in WebStorm/PhpStorm.

Note: Use and implement solution 1 because this method fully tested our system.
