NUC5CPYH の 1 つの HDMI ポートと VGA ポートを使用して、Ubuntu 18.04 のデュアル モニターをセットアップしようとしています。今のところうまくいきません。VGA のみのポート (HDMI なし) が接続されていても、BIOS 画面は表示されません。VGA をプライマリ ディスプレイとして使用するように BIOS を設定しましたが、役に立たないようです。
モニターにはまだ「信号なし」と表示されます。奇妙なことに、接続すると Ubuntu がそれを認識し、ディスプレイ設定でモニターを認識します。マウス (カーソル) を画面の右外に移動すると、マウスはモニター (何も表示されていない) 上にあるかのように動作します。使用している 2 つのモニターは同じもので、テストのために交換しましたが、どちらも正常に動作しています。Benq GW2280 モニターです。ドライバーの問題ではないかと考えています。
