Comment 12 for bug 191451

Ok. I've just check the console-setup package content and now I can see where it does apply. But yet I'm not sure to understand when the console-setup debconf options are configured during the installation. Is it from gfxboot or later from ubiquity?

In fact we face problem as soon as we choose the "Vietnamese" language in gfxboot since it does imply a "vn" keyboard which really should be "us" instead.

Then we face another problem when we run GTK2 applications (first with GDM, then with Ubiquity). It's because GTK2 has one of its default immodules (im-viqr.so) hinted for the "vi" language (see the result of "gtk-query-immodules-2.0") and so being automatically selected when in the "vi_VN" language environment. Here we probably need some GTK_IM_MODULE setting to disable this.

In a final Vietnamese configuration we set it to scim, and I think it may apply to most of, if not all, other languages too. So I would recommend to let it be the default, especially before running Ubiquity.
