startx を使用したデュアル モニター セットアップが機能しない

startx を使用したデュアル モニター セットアップが機能しない

私には 2 つのモニターがあり、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:

  • モニターAはchromium-browserを実行する必要があります
  • モニターBは別のChromiumブラウザ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

ランレベル 2 の init スクリプトには次の内容が含まれています。

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.confxorg.conf と同じです:

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、この設定では 1 つのモニターしか動作しないことです。つまり、次のようになります。

Chromium ブラウザで Youtube ビデオを再生しています。1 つの startx は動作していますが、別のモニターは空白になっているようで、次のエラーが表示されます。

(++) Using config file: "/home/atled/displaylink.conf"

Fatal server error:

答え1

ディスプレイとモニターは同じものではありません。

各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、これは望ましいことではありません。

:01 つのディスプレイ ( ) と 2 つのモニター (:0.0:0.1)を備えた 1 つの X サーバーを起動します。

startx起動するには1 回の呼び出しが必要で:0、スクリプトは両方のアプリケーションを起動し、そのうちの 1 つをパラメータを使用して 2 番目の画面に移動します--window-position

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。

答え2

Darth の言うとおりです。また、 では(for ) と(for )xorg.confの両方を参照していますが、定義されているセクションは 1 つだけで、それは です。monitor0screen0monitor1screen1monitormonitor0

私の推測では、画面が見つからないというエラーは、X が検索しようmonitor1としたが存在しないために発生します。
