Ubuntu 18.10にアップグレードし、NVIDIAドライバーを使用していないため、まったく同じ問題があります。黒い画面から再開すると、すべてが応答しなくなり、どういうわけかグラフィカルセッションを再起動する必要があります。また、[外部ディスプレイ]を[シングルディスプレイの設定]に設定して使用しています。これは私のシステムです：

後でさらにテストとデバッグを行いますが、私が一人ではないことを知っておくのは良いことです。
新しいNouveauドライバーはハードウェアと互換性がないようです（リバースエンジニアリングされたドライバーでは時々一般的です）。
- それらを削除してみてください（Intelドライバーのみを使用してください）。
- nVidia Proprietaryドライバーの使用
- お使いのシステムでNVidia Optimusがサポートされているかどうかを確認してください。しばらくこれをいじる必要はありませんでしたが、便利な「バンブルビー」ツールがありました。
