How do I change my keyboard layout in gnome shell?
In Gnome Shell 3.18.5, there is no way to change the keyboard layout through the settings panel at all that I could find. Instead, the settings are located in the Gnome Tweak Tool under "Typing".
If you don't have it, you can install Gnome Tweak Tool with
sudo apt-get install gnome-tweak-tool
and access it from the Activities menu.
You'll find the keyboard layout settings in the region and languages setting panel. Go to the user menu, choose System Settings, then Region and Language, then switch to the Layouts tab.
The layout chooser and keyboard shortcuts (under options) should be pretty familier from the Gnome 2 days. Once there is more than one layout you should get a little switcher applet too.
This worked for me... got to:
System Settings --> Keyboard layout, tab Layouts --> Options... Key(s) to change layout
Pick any one you like, even multi options work for me...
