メイトデスクトップで背景を変更できません
MATEデスクトップ1.16.1でDebian Stretchを実行しています。パッケージを更新したのでmate-settings-daemon背景を変更できないので、ログイン画面に使用されている壁紙が表示されます。コントロールセンター->外観->背景を使用して通常の方法で変更しようとしましたが、新しい壁紙を選択しても何も起こりません。dconf editorを使用して一部の構成を変更しようとしましたが、もう一度成功。

私は同じ問題を抱えています。
簡単な回避策は、fehを使用することです。
feh --bg-scale <imagefile.jpg>
fehを必要としない別のソリューションは次のとおりです。
デスクトップの壁紙がログインの背景で動かなくなっているようです。したがって、ログインの背景を変更することができ、その後必要なのはログアウトして再度ログインすること（再起動ではない）だけです。
ログインの背景の変更は pdate-alternatives を介して行われます（誰かがより良い方法を知っている場合は、教えてください）。 rootユーザーとして、コマンドラインから2つのコマンドを発行する必要があります。
update-alternatives --install /usr/share/images/desktop-base/login-background.svg desktop-login-background /absolute/path/of/your/image 50
update-alternatives --set desktop-login-background /absolute/path/of/your/image
次に、ログアウトして再度ログインすると、壁紙が選択したものになります。私がその質問に気付かなかったとき、これは少なくとも私にとってはうまくいったものです。私がいたらいいのに。うまくいけば、バグが修正されるので、それは私がせっかちなことだと思います。
バグが修正されました：最後の更新後、問題が修正されたため、関連するメニューから背景を変更でき、期待どおりに機能するはずです（機能した少なくとも私にとっては）。
