この設定では外部モニターのみが機能しますが、2つの間で回線を切り替えるとScreen 0ノートブックモニターのみが機能します。Screen 1Section "Device"

答え1

同様の問題があります。 HDMI外部モニタのみが機能し、ノートパソコンの画面は機能しません。 Fedora 32を使用してください。

多くのテストオプションの後、次の/etc/X11/xorg.confで動作するようにしました。ここでの鍵は次のとおりです。NVIDIA GPU画面を許可オプション。これにはPrime Rendering Offloadをサポートするグラフィックカードが必要です（私のカードはNvidia GeForce RTX 2060です）。
