外部モニター専用 Nvidia Driver/X [ディスプレイポート]

Bumblebeeが私の外部モニターと連携することができなくなった後（xrandrはそれを「認識しない」）、Debianを再インストールしました。 Nvidia Dev Forum（atmが見つかりません）で384のインストール提案が見つかりました。この設定により、NVIDIAが外部モニタでXを使用できるようになりました。ディスプレイマネージャとしてgdm3を使用しています。モニターなしで実行すると、Xが（EE）見つからない画面で競合が発生します。

WaylandEnable=falseコメントしてこの設定を元に戻すと、ノート/etc/gdm3/daemon.confパソコンのモニターでGnome（Wayland）を起動できます。ウェイランドで起動すると、起動時にループが発生します。

Nvidiaに2つの画面を認識させるにはどうすればよいですか？
