私は最近、Cinnamonデスクトップ環境を備えた新しいノートブック（タッチスクリーン付きのDell XPS 13）にDebian Stretch（テスト）をインストールしました。 Intelグラフィックカードの場合xserver-xorg-video-intel。ログインすると、数秒（ほとんど）後に画面が消えます（バックライトなし、ピクセルなし）。これが「ふたの開閉」イベントを受け取るsystemdおよびcinnamonの問題である可能性があることに気づいたので、次のように/etc/systemd/logind.conf修正しました。

これによりシナモンだけがふたイベントを担当することになります。まだ画面が消え続ける場合があります（画面を「再起動」するには、カバーを閉じる必要がありますが、ログインとは何の関係もないようです）。何の問題もないようですが、Xorg.conf私が間違っている可能性があります。これはXorg.logです：
