我正在运行 CentOS Linux 版本 8.4.2105，内核：4.18.0-305.19.1.el8_4.x86_64。我使用的戴尔内置 Intel 显卡和 NVIDIA Quadro M1000M GPU，运行 kmod-nvidia-470.74-1.el8_4.elrepo.x86_64。机器是 Dell Precision 7510，配备 Xeon E3-1505M 我最近运行了 dnf 更新....[微笑消失]
看来英特尔图形控制器已经……消失了。这是一个单独的问题，但有必要进行解释，在我安装 Nvidia 驱动程序后，X 从未自动启动。我会启动并进入终端，登录，然后必须手动执行：startx 来启动桌面环境；有点不便，但我真的不在乎。无论如何，相同的过程，在启动时我像往常一样进入终端，然后出现这个在我笔记本电脑的内部显示屏上; LCD，但是当我：startx时，我只能在外部显示器上看到视频，例如HDMI。

英特尔 VGA 控制器在哪里？更麻烦的是 BIOS 中的系统信息，我看到：
Video Controller Error!
Video BIOS Version Error!
Video Memory Error!
Panel Type Error!
Native Resolution Error!
我有我的 Xorg.0.log 和 dmesg，但目前不知道如何附加这些（这里的第一篇文章...），很快就会解决这个问题并上传。
我尝试恢复内部监视器的事情：
sudo dnf history undo transaction_num # really wished that would have worked; errored with unable to locate packages
sudo dnf reinstall xorg-x11-drv-intel.x86_64 # reinstall the intel driver
sudo dnf -y reinstall `rpm -qa | egrep -i "xorg|mesa"` # reinstall all of X
sudo dnf reinstall $(rpm -qa | grep mesa) # reinstall mesa
reinstall nvidia driver
removed/renamed /etc/X11/xorg.conf to xorg.conf.BAK
到目前为止，没有任何效果，我已经没有主意了。
更新：

我也尝试过清除CMOS，但没有成功。
