雙 GPU 雙顯示設定：顯示器黑屏但已偵測到

我最近在 Windows 10 上安裝了 linux，並且嘗試像在 Windows 上使用第二台顯示器一樣使用它。
第一個顯示器連接到 GTX 770，第二個顯示器連接到 iGPU。我已經設定了一個 xorg.conf 檔案來使用兩個監視器，但只有第一個可用。第二個是黑色的（它有點工作，因為我可以在其上移動滑鼠並看到指針，但我無法在其上拖曳視窗。
此外，當我運行xrandr --query或xrandr --listmonitors只看到第一個螢幕（HDMI- 0）時：顯然，第二個顯示器（HDMI1）甚至沒有被檢測到，但是當我運行時，xrandr --screen 1它顯示第二個螢幕（HDMI1）很好：已連接，工作，解析度自動分配（甚至正確） ，...
問題是
我找不到讓它可用的方法。
