Ubuntu – Alt+shift can’t be set to toggle language


I recently did a fresh installation of Ubuntu 13.10; but there is something bothering me, which I don't quite understand.

When I first tried to toggle the keyboard language(I usually switch between Persian and English) using the good old "Alt+Shift" shortcut it didn't work. Then, I went and checked the Keyboard shortcut settings and found out that it had been set to "Super+Space"(which BTW didn't work either). So I tried to change it back to "Alt+Shift" but it just doesn't work; when I press "Alt+Shift" to set it up as the toggle-language shortcut, the box automatically resets itself to its previous value(without any errors whatsoever). As far as I've checked I couldn't find any thing obvious corresponding to the shortcut "Alt+Shift" either.

I've currently set up the shortcut as "Ctrl+Space"; so I can toggle the language. My question is why I cannot set it up to just "Alt+Shift"?

  • I had the same problem after upgrading to Saucy.

    Here's how I fixed it. First you need dconf-editor, so just install it by typing (in a terminal):

    sudo apt-get install dconf-editor

    After installed run it by typing


    In the new window browse to Desktop -> ibus -> General -> Hotkey
    then change the next-engine & next-engine-in-menu values to something like this:


    Close the window and go to the text entry settings.
    They should now allow you to use Alt+Shift

    if the above doesn't help, try this :

    sudo add-apt-repository ppa:attente/1218322
    sudo apt-get update
    sudo apt-get upgrade

    then restart.
