How to change "Keyboard Input Method System" to "None" in Ubuntu GNOME?

Question

Every time I install the default version of Ubuntu 14.04 (with Unity), I go to "Language Support" and change the option "Keyboard Input Method System" to "None", because I need it that way.

Today, I installed Ubuntu GNOME 14.04 and I can't find this "Keyboard Input Method System" option anywhere. Please, how do I change this when using Gnome Shell?

Thanks for your attention.

Solution 1

You can use im-config to change this. My system wil laccept ibus or xim. The latter reports as "none" in the GUI.

im-config -n ibus
im-config -n xim

Solution 2

In Terminal:

$ gnome-language-selector

Open the Language tab, and there you can choose IBus or None.
