Ctrl-Alt-F1と入力して、ターミナルセッションにログインします。sudo grep metacity /var/spool/log/*

@Aliot Xorgログのエラーもトラブルシューティングに役立ちます。 sudo grep EE /var/log/Xorg.0.log

dpkg-reconfigure metacityを試しましたか？（mysefを実行したことはありませんが、失敗した場合、メタシティまたはサーバーXの構成に問題がある可能性があります）

これは私の友人が直面したものとまったく同じです。また、Chromeを実行すると、セッションが常に突然ログアウトすることに気付きました。特定のプログラムの実行中にこれを経験しましたか？これは確かにバグです。あなたの場合、それは「メタデータ」のようです。別のWindowsマネージャープログラムを使用してみてください。

ハードウェア固有の情報がありますか？ターミナルを開いてlspciと入力し、出力を送信してください。また、テーマをインストールしたり、GUIを変更しましたか？

これは未解決ですが、gnome-flashbackセッションを使用している場合は比較的まれなバグです。ほとんどすべてがデフォルトのUIを使用しているためです。詳細を参照し、サブスクライブして問題が解決したかどうかを確認してください：https : //bugs.launchpad.net/ubuntu/+source/xorg/+bug/1455916

一時的な修正-gnome-flashbackセッションを使用しないでください。
