Comment 8 for bug 1719938

Right, so the current behaviour is not an Ubuntu bug but how current GNOME behaves. They believe it's not possible to "guess" what input method an user for a defined locale is going to need and don't want to have a cluttered menu with a bunch of options which the user is not going to need.

The recommended way to set it up on the installed system is to use gnome-initial-setup on first login (which we don't do in Ubuntu), that wouldn't resolve the installer/live cd cases though where the user is just going to need to use the settings to configure it.

That's not a simple fix but something we need to give more consideration to next cycle, I'm lowering the importance and unassigning, it's not likely we change anything for artful now.
