Debian 10 で 2 台目のモニターを検出できません。 NVIDIAグラフィックカードを介して接続されているモニターの1つが検出され、正しく機能します。他の画面はIntel統合グラフィックスを介して接続されており、何を試しても設定にまったく表示されません。 BIOSでマルチスクリーンを有効にしてハードウェアを確認するためにケーブルと画面を切り替えてみましたが、両方の画面（および関連するケーブル）が正しく機能しています。

LSPCIで2台目のモニターが最初から出てくるケースは見られませんでした。私の統合グラフィックに何か欠けているようですが、何かわかりません...

/etc/X11/xorg.conf.d/nvidia.confNvidia独自のドライバをインストールした後は、X11サーバーに独自のドライバを使用するように指示するファイル（またはファイル）が必要です/etc/X11/xorg.conf。残念ながら、デフォルトでは、X11サーバーはそのドライバを使用する必要があると思います。ただ。
Section "Device"Intelドライバも指定して2番目のブロックを追加する必要があります。
機器セクションは次のとおりです。
Section "Device"
Identifier "IntegratedIntel"
Driver "modesetting"
BusID "PCI:00:02.0"
EndSection
2つのデバイス部分を一緒に接続するには、画面部分が必要な場合があります。
Section "Screen"
Identifier "nvidiaScreen"
Device "DiscreteNvidia" # put the actual Identifier of your Nvidia GPU Device section here
GPUDevice "IntegratedIntel"
EndSection
これにより、Xorg X11サーバーはNvidia GPUをデフォルトのGPUとして使用する必要がありますが、Intel GPUのドライバもロードする必要があることを伝えます。
適切なX.orgドライバパッケージをインストールしたと仮定すると、xrandr --listproviders2つのプロバイダが表示されます。それから（つまり、xrandr --setprovideroutputsource 1 0「しよう出力プロバイダ 1 は、プロバイダ 0 を次のように使用します。源泉）コマンドは2つのGPU間の接続を確立する必要があります。パラメータなしで成功した場合は、xrandr両方のGPUのコネクタとそれに接続されているモニタを表示する必要があります。
次に、2番目のモニターで何をするかを指定します。つまり、最初のモニターが表示する内容をコピーするか（プレゼンテーションの場合など）、デスクトップを拡張するために使用するかを指定します。 2 台目のモニター 1 台目のモニターに基づく最初のモニターの物理的な位置です。
