无法在内置屏幕上使用 GUI，只能在 HDMI 端口上使用

Ubuntu 启动后，我无法使用笔记本电脑的内置显示器作为 GUI 桌面。当我使用 Ubuntu 20.4.1 LTS 时，内置显示器和外接显示器都可以工作，我还可以使用WIN+P来扩展桌面。我现在有 Ubuntu 22.04.1 LTS。升级后，我不得不重新安装 NVIDIA 驱动程序。

我有一块英特尔集成显卡和一块 NVIDIA GeForce 1050 移动 GPU。我安装了 NVIDIA 驱动程序（版本 515.65.01），我可以使用第二台显示器，我可以通过 HDMI 连接它（连接到 NVIDIA GPU 卡）。一切都运行正常，只是 Ubuntu 无法识别内部屏幕。当我切换到英特尔显卡sudo prime-select intel并重新启动时，我进入终端并startx退出并出现错误。

如果我启动笔记本电脑时没有连接任何 HDMI，它应该会挂起在文件系统检查上。如果我通过 HDMI 连接屏幕，我会在该显示器上看到我的登录屏幕，而内置屏幕会变黑。

当我使用 NVIDIA X Server GUI 更改某些设置并改变文件时，问题可能就开始了/etc/X11/xorg.conf。

我已经尝试删除它/etc/X11/xorg.conf然后重新生成它sudo nvidia-xconfig，但没有任何改变（除了xorg.conf文件的布局）。

当我启动 Windows 时，笔记本电脑屏幕工作正常（我有双启动但实际上只使用 Ubuntu），所以我认为一定是我的某些驱动程序设置错误。
