Ubuntu 17.10 and later: can't change the input switching shortcut to alt+shift

  • 772

When I try to set the default combo for switching to different language layouts in my keyboard from Shift+Super+Space to Alt+Shift I can't.

I used to have this combo since Ubuntu 14 and even before that when I used to have Windows. Now for some stupid reason it does not allow (actually nothing happens its not like I get an error or the combo is used elsewhere). How could I bypass this bug?

    You may use (GNOME) Tweaks to achieve your goal. First install it by running 

    sudo apt install gnome-tweaks

    (on Ubuntu 18.04 and later) or 

    sudo apt install gnome-tweak-tool

    Launch Tweaks and go to Keyboard & Mouse section. Click on the "Additional Layout Options".

    enter image description here

    A new window should pop up. Look for "Switching to another layout" and expand it. Then check the "Alt+Shift" option.

  2. You can achieve this using gsettings (command-line configuration tool).

    1. Set forward switch to Shift+Alt(left)

      gsettings set org.gnome.desktop.wm.keybindings switch-input-source "['<Shift>Alt_L']"

    2. Set backward switch to Alt+Shift(left)

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

    To see the current setting value use get command:

    gsettings get org.gnome.desktop.wm.keybindings switch-input-source
gsettings get org.gnome.desktop.wm.keybindings switch-input-source-backward

    Examples of other key bindings:

    <Primary>space, Alt_R, <Shift>Control_R, <Shift><Super>space

    Changes will take effect immediately.

  3. Ubuntu 20.20, gnome flashback, the gsettings option didn't work for me. This fixed the problem (copied from my other machine):

    gsettings set org.gnome.desktop.input-sources xkb-options "['grp:alt_shift_toggle', 'grp_led:scroll', 'lv3:switch']"

    Keyboard shortcuts still show Super+Space combination, and it still works, but Alt+Shift works as well.
