Ubuntu – Alt-Gr key is not working in Ubuntu 13.10

keyboard-layout

I installed Ubuntu with mostly default configuration; the keyboard seems not to detect the Alt-Gr key so that I can not type international characters.

How can I enable Alt-Gr key?

This answer has screenshots for Gnome-Shell (Ubuntu Gnome 13.10). I suppose it will be similar for standard Unity, but if not, please chime in.

First of all (and this is the most common problem), to have AltGr working you need a keyboard layout which uses it. For example, this is my keyboard layout (Settings -> Region and Language):

Screenshot: Region & Language settings

  • English (US, international with dead keys) has AltGr.
  • English (US) has NO AltGr.
  • English (international AltGr dead keys) has AltGr.

(My preferred layout is the third one, really).

If the layout does not map AltGr+Key to anything, like for example the default "English (US)", AltGr will not work even if it's activated in the Keyboard -> Shortcuts panel.

This is normally sufficient. To change the position of the AltGr you go to Settings -> Keyboard and set the "Alternative Characters Key":

For example, my keyboard has no physical AltGr key, so I mapped it to the Right Alt key.

Now with the third layout, pressing AltGr and n together gives ñ.

Compose (the option before) is a very different beast. If you enable it, then you will have a set of characters available with three (or more) keystrokes. For example, pressing Compose, o, e gives œ. That's three sequential keystrokes, not together.

Take into account that there is a bug related to the layout switching in 13.10 which is being worked on, so check it if you have problems changing layout.
