答案1
嗯，看起来 Xorg 正在尝试使用 NVIDIA 卡。你试过了吗指定 Xorg 应该使用哪个 GPU？
启用 vfio_pci 后 X 无法启动
这与主机 GPU 被检测为辅助 GPU 有关，这会导致 X 在尝试为客户 GPU 加载驱动程序时失败/崩溃。为了避免这种情况，需要一个指定主机 GPU 的 BusID 的 Xorg 配置文件。可以从 lspci 或 Xorg 日志中获取正确的 BusID。来源 →
/etc/X11/xorg.conf.d/10-intel.conf
Section "Device" Identifier "Intel GPU" Driver "modesetting" BusID "PCI:0:2:0" EndSection
如果xorg.conf.d尚不存在，则只需创建它。
此后，Xorg 不应再尝试使用 NVIDIA 显卡。Arch Wiki 页面列出了其他问题，随着您进一步了解，您可能会发现这些问题很有趣。
答案2
我在台式电脑上安装第二个 NVIDIA GPU 后遇到了相关问题。尝试启动时，日志显示 gdm（Gnome Display Manager 3）已启动，但我只看到左上角有一个闪烁的光标。
正如 @Daniel B 在接受的答案中提到的那样，修复与 Xorg 配置文件有关。我能够使用 NVIDIA 实用程序生成正确的配置文件。
- 启动到运行级别 3（允许在图形启动失败时获取终端）：e在引导加载程序屏幕上按下，然后将其添加
3到行尾linuxefi并使用 开始引导ctrl + x。 - 使用您的标准用户名和密码登录。
- 备份任何现有的 Xorg 配置：
sudo cp -r /etc/X11/xorg.conf.d /etc/X11/xorg.conf.d.bak - 使用 NVIDIA 的工具创建新的 Xorg 配置：
sudo nvidia-xconfig -a - 新的配置文件可能没有放在正确的位置。如果
/etc/X11/xorg.conf.d/10-nvidia.conf存在或类似情况，请确保已备份，然后将新的配置文件复制过来：（sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.d/10-nvidia.conf我必须在 Fedora 29 上执行此操作）。 - 重启：
sudo reboot
请注意，上面的路径对应于 Fedora 29，可能需要根据您的发行版存储这些配置文件的位置进行调整。
