startxを使用したデュアルモニターのセットアップが機能しない

私は2つのモニターを持っており、それぞれで2つの異なるアプリケーションを実行していました。例えば。

  • モニターAはクロムブラウザーを実行する必要があります
  • モニターBは別のクロムブラウザーを実行する必要があります

これは、システムの起動後に実行する必要があります。

以下のxorg.conf

Section "ServerFlags"

        # Even if mouse detection fails, X will start
    Option         "AllowMouseOpenFail" "yes"
        # VT switching is disabled
    Option         "DontVTSwitch" "yes"

        Modes      "1920x720"

EndSection

Section "ServerLayout"

    InputDevice "mouse1"
    InputDevice "keyboard1"

ランレベル2のinitスクリプトには、次のものがあります。

startx /path/to/screen-0-app.sh -- :0 -layout Layout0 -config /path/to/displaylink.conf -nolisten tcp vt7 -novtswitch -sharevts &

startx /path/to/screen-1-app.sh -- :1 -layout Layout1 -config /path/to/displaylink.conf -nolisten tcp vt8 -novtswitch -sharevts &

displaylink.conf xorg.confと同じ：

screen-0-app.sh and screen-1-app.sh consist of 

exec xterm -e xrandr -s 1920x1080 &

exec chromium-browser --user-data-dir=~/.chromium --window-size=1920,1080 --window-position=0,0 --kiosk --incognito http://www.youtube.com/watch?v=MRbI6LwLz94

another screen consist of different youtube link with same setup

問題は、1台のモニターがこのセットアップで動作していることです。つまり、次のことを意味します。

クロムブラウザで再生しているYoutubeビデオ1つのstartxは機能していますが、別のモニターが空白になっているようで、エラーが発生します。

Fatal server error:

ディスプレイとモニターは同じものではありません。

モニターごとに個別のXサーバーとディスプレイを起動しようとしていますが、これは目的ではありません。

1つのディスプレイ（:0）と2つのモニター（:0.0と:0.1）で1つのXサーバーを起動したいとします。

:0を起動するために1回のstartx呼び出しが必要であり、スクリプトは両方のアプリケーションを起動し、--window-positionパラメーターを使用して一方を2番目の画面に移動する必要があります。

モニターが並んでいて、最初のモニターが1920x1080で、左上隅が0,0の場合、2番目のモニターの左上隅は1920,0になります。

ダースが言ったこと。また、_xorg.conf_では、_monitor0_（_screen0_の場合）と_monitor1_（_screen1_の場合）の両方を参照していますが、定義されているmonitorセクションは1つだけです。は_monitor0_です。

画面が見つからないというエラーは、Xが_monitor1_を見つけようとしているが、それが存在しないためだと思います。
