無法在內建螢幕上使用 GUI，只能在 HDMI 連接埠上使用

Ubuntu 啟動後，我無法將筆記型電腦的內部顯示器用作 GUI 桌面。當我使用 Ubuntu 20.4.1 LTS 時，內部顯示器和外部顯示器都可以工作，而且我還可以使用WIN+P來擴展我的桌面。我現在有 Ubuntu 22.04.1 LTS。升級後我必須重新安裝 NVIDIA 驅動程式。

我有一個 Intel 整合式圖形晶片和一個 NVIDIA GeForce 1050 行動 GPU。我已經安裝了 NVIDIA 驅動程式（版本 515.65.01），並且可以使用我的第二台顯示器，該顯示器可以透過 HDMI（連接到 NVIDIA GPU 卡）連接。一切運作正常，除了 Ubuntu 無法辨識內部螢幕。當我使用並重新啟動切換到英特爾圖形晶片時，sudo prime-select intel我最終進入終端並startx退出並出現錯誤。

如果我在沒有連接任何 HDMI 的情況下啟動筆記型電腦，它可能會掛在檔案系統檢查上。如果我隨後透過 HDMI 連接螢幕，我會在該顯示器上看到登入螢幕，並且內建螢幕會變黑。

當我使用 NVIDIA X Server GUI 更改某些設定（更改了檔案）時，問題可能就開始出現了/etc/X11/xorg.conf。

我已經嘗試刪除/etc/X11/xorg.conf然後使用 重新生成它sudo nvidia-xconfig，但沒有任何更改（文件的佈局除外xorg.conf）。

編輯

當我啟動Windows時，筆記型電腦螢幕工作正常（我有雙啟動，但只真正使用Ubuntu），所以我認為這一定是我弄錯了一些驅動程式設定。

添加了 的輸出xrandr --listproviders。此外，我意識到PRIME ProfilesNVIDIA X 伺服器設定中不再有任何命名的條目： NVIDIA X Server GUI 的螢幕截圖
