Ubuntu MATE 18.04を使用しています。
私はLightDMをディスプレイマネージャとして使用すると思います。同じデバイスに2つのモニターが接続されています（ポート2つ、HDMI 1つ、VGA 1つを搭載したIntel HDオンボードグラフィックス）。
私が実行しているアプリケーションの特性により、2つの別々のX11画面が必要です。その間にマウスを動かさなければならないが、それ以外は独立でなければなりません。モニタ間でウィンドウを移動できないでください。
私は1つのモニターと2つの画面（各画面に1つのモニター）を使用する設定が機能すると思います。
ディスプレイマネージャのGUIアプリケーションを使用して1つのモニタを拡張すると、同じ画面に表示されます。
1つのモニター、2つの画面、画面ごとに1つのモニターが私の要件を満たしていると思うのは正しいですか？
どのように設定しますか？
私はこのガイドに従っています：
- デュアルモニター (Gentoo Linux Wikiから)
返品
UbuntuでIntel HDグラフィックスを使用したデュアル画面設定（Ubuntuについて尋ねる）
Xorg：スタンドアロンモード(UnixとLinuxで)
1枚のカードに複数のXスクリーンを構成する （nvidia.comから）（ZaphodHeadsは言及されていません）
私が望むのはZaphodHeadsと呼ばれる継ぎ目です。同じデバイスの複数の画面です。
しかし、私が得た結果は、左上にテキストカーソルだけを持つ2つの空の画面です。
私が見るにはこれが問題のようです：

この設定を適用するにはLightDMを構成する必要がありますか？

私はあなたが望む設定について多くの経験を持っています。カスタムxorg.confを作成する必要があります。 Intelグラフィックアダプタがある場合は、ZaphodHeadsを使用することをお勧めします。例は次のとおりです。

lspciグラフィックアダプタが接続されている場所を確認するには、コマンドラインを入力してください。 BusIdで定義されています。より多くのものがあれば非常に便利です。 1つしかない場合はオプションです。xrandrドライバが認識する出力を確認するには、入力してください。この例では、アクセラレータが無効になっています。必要に応じて有効にできます。より多くのレイアウトを作成し、セクションDefaultServerLayoutで使用するレイアウトを指定できます。
以下はNVidiaの例です。

答え2
startx/をxinit単一のプログラムとしてお持ちですか？
LightDMを終了してマニュアルページを読んでxinit欲しいことができると思います。 （いいえ、LightDMはこの使用法をサポートするために書かれていないと思います。）
これにはカスタム作成を含めることができますxorg.conf。
答え3
Xfceを使用したDebian-11でも同じ問題が発生しました（2つの空の画面、カーソルのみ）。次のように、xorg.confで「モード設定」ドライバ（Intelの代わりに）を強制的に適用してこの問題を解決しました。
Section "Device"
# Identifier "Intel Graphics"
# Driver "intel"
Identifier "Modesetting"
Driver "modesetting"
Option "AccelMethod" "sna"
EndSection
私の問題はなぜ解決されましたか？
xorg.logで見つかったエラーは次のとおりです。
xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted)
上記のエラーメッセージをインターネット検索して見つけました。
https://github.com/dnschneid/crouton/issues/2926
いくつかのヒントを得てみましたが（たとえそのページはまったく異なる問題に対処しています）、効率的。
