スリープモード後の黒い画面:ホットプラグイベント:コネクタのリンク状態が悪い。

スリープモード後の黒い画面:ホットプラグイベント:コネクタのリンク状態が悪い。

私のラップトップは過去にうまくいきましたが、過去数ヶ月間、特定のイベントの後にラップトップの画面が目覚めない問題がありました。デフォルトでは、ノートパソコンのサスペンド後にコンピュータを起動したときに画面が点灯しない時間は約15%です。一定期間使用しない場合は、画面が黒くなっても同様の割合の空白の画面が表示されます。マウスを動かすと、目が覚めないことがあります。

活動がなく、画面が黒くなった後(停止した時よりログ項目が少なくて)、画面がオンにならない状況を検討してみました。画面が黒くなり、マウスを再度動かしている間は、Journalctlエントリはありません。しかし、xorgログで次のものが見つかりました(タイムスタンプを復号化できませんが、これはログファイルの終わりです)。

私が見つけることができる唯一の関連トピックは次のとおりです。https://bbs.archlinux.org/viewtopic.php?id=236359- しかし、解決策はありません。私はシステムを最新の状態に保ちました。 i3をウィンドウマネージャとして使用してArch Linuxを実行します。私のカーネルは4.14.52-1-ltsです。この問題の原因は何ですか?
