nouveauドライバーはサスペンドを防ぎ、私もそれを必要としません
統合されたIntel GPUと個別のNvidiaの両方を備えたDell XPS 15を持っています。 Nvidia X Server Settingsプログラムを使用して、省電力の理由から、システムをIntelシステムを使用するように設定します。とにかく、nouveauドライバーがロードされます。この場合、ほとんどの場合、サスペンドしようとすると、サスペンドが失敗し、ロック画面になります（そして、正常にロック解除できます）。一度ブルームーンになると、それは機能します。
今では、nouveauドライバーをサスペンドで動作させるソリューションに満足していますが、とにかくIntel GPUを使用しているので、ドライバーをまったくロードしないことでも問題ありません。
18.04とカーネル4.15.0-20を実行しています。

Nvidia X Server Settingsを使用して独自のnvidiaドライバーに切り替える場合、上記を変更してそれを反映し、サスペンドは正常に機能します。 （実際にはそれは真実ではありませんが、それは別のより劇的な方法で壊れます、そして私は気にしません。）
/etc/modprobe.d/（作成しなかった）にnouveauをブラックリストに載せると思うファイルがいくつかあります。 cat /etc/modprobe.d/nvidia-graphics-drivers.conf /etc/modprobe.d/blacklist-nvidia.confの出力：

同じ/var/log/syslogには、nouveau 0000:01:00.0: timeoutと同様の苦情が含まれます。一時停止が成功するまれなケースでは、ログにはnouveauに関するこのすべてのくだらない情報がありません。
問題を修正する方法（素晴らしい）またはnouveauを無効にする方法（良い）の指針はありますか？ /etc/modprobe.d/ブラックリストファイルがドライバー全体の読み込みを妨げないのはなぜですか？手動でアンロードするにはどうすればよいですか？ （modprobe -rを試してみましたが、あまり成功しませんでした。）
どのドライバーをロードするかを管理するbumblebeeをインストールすることでこれを修正しました。現在、ディスクリートGPU用の独自のnvidiaドライバーが読み込まれているため、動作が中断されます。bumblebeeは、特に指定がない限りデフォルトでIntel GPUを使用するため、バッテリーと鼓膜を燃やしていません。
最大の解決策ではなく、回避策なので、何かもっと良いものを投稿してください。しかし、私は自分が欲しいものを手に入れ、さらに調査するのが面倒だと感じました。
