Hello,

After a painful debugging session where I was blaming GDM for not using
the right keyboard layout, I found that I had specified an invalid
keyboard layout variant, as in:

  (keyboard-layout "fr" "does-not-exist")

=E2=80=98ckbcomp=E2=80=99 would build a layout for the console just fine, o=
nly with a
warning.  Xorg would switch to the default =E2=80=9Cfr=E2=80=9D layout (whi=
ch exists)
and ignore the =E2=80=9Cdoes-not-exist=E2=80=9D variant.

However, GNOME Shell would reject it in =E2=80=98keyboardManager.js=E2=80=
=99 because:

     [found, , , _layout, _variant] =3D this._xkbInfo.get_layout_info(id);

returns =E2=80=98found =3D false=E2=80=99 since =E2=80=98fr+does-not-exist=
=E2=80=99 is not found, and thus
goes on to use the US layout:

      if (found)
          return { layout: _layout, variant: _variant };
      else
          return { layout: DEFAULT_LAYOUT, variant: DEFAULT_VARIANT };

(This is just for GNOME Shell because again, Xorg itself installs the
=E2=80=9Cfr=E2=80=9D layout, as can be seen if you start ratpoison or simil=
ar.)

Long story short: it would be great if invalid keyboard layouts were
caught when the system is instantiated.  It could be =E2=80=98ckbcomp=E2=80=
=99 errorring
out, or we could have additional code that browses xkeyboard-config=E2=80=
=99s
=E2=80=98base.xml=E2=80=99 file.

Ludo=E2=80=99.
