キーボードレイアウト切り替えキーの組み合わせが機能しません。

00-keyboard.conf次のオプションを使用してファイルを作成しました/etc/X11/xorg.conf.d/。

Section "InputClass"
        Identifier "system-keyboard"
        Option "XkbLayout" "latam,ru"
    Option "XkbVariant" ",qwerty"
        Option "XkbOptions" "grp:alt_shift_toggle"
EndSection

の出力は/var/log/Xorg.0.log次のとおりです。

Alt+Shift を押すと、何もしません。私はDebian Jessieを使用しています。

しかし、setxkbmap -option grp:alt_shift_toggle latam,ru期待どおりに動作します。
