我有一台配备 nvidia GTX 1050 的 dell xps 15 9560，在内核 5.1.x 下的 Xorg 上使用 gnome 在 ubuntu 18.04 上尝试运行 nvidia 驱动程序 430（ubuntu-drivers 推荐的驱动程序）时遇到了问题。
我已经尝试过执行sudo apt purge nvidia-*、重新启动并安装它，通过sudo apt install nvidia-driver-430或sudo ubuntu-drivers install，重新启动时，“设置”>“关于”面板一直说我正在使用英特尔 HD 630 显卡，而且 nvidia-smi 指出没有 nvidia 显卡正在运行或没有安装 nvidia 驱动程序。
我有以下 grub 命令：
GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_rev_override=1 nouveau.modeset=0 nouveau.runpm=0 noresume intel_pstate=skylake_hwp"
grep -rnw /lib/modprobe.d/ -e "nvidia"给出了以下结果：
/lib/modprobe.d/nvidia-kms.conf:1:# This file was generated by nvidia-prime
/lib/modprobe.d/nvidia-kms.conf:3:options nvidia-drm modeset=1
/lib/modprobe.d/blacklist-nvidia.conf:2:# This file was generated by nvidia-prime
/lib/modprobe.d/blacklist-nvidia.conf:3:blacklist nvidia
/lib/modprobe.d/blacklist-nvidia.conf:4:blacklist nvidia-drm
/lib/modprobe.d/blacklist-nvidia.conf:5:blacklist nvidia-modeset
/lib/modprobe.d/blacklist-nvidia.conf:6:alias nvidia off
/lib/modprobe.d/blacklist-nvidia.conf:7:alias nvidia-drm off
/lib/modprobe.d/blacklist-nvidia.conf:8:alias nvidia-modeset off
使用内核 5.0 和 nvidia 驱动程序 418 我没有遇到任何问题，但尝试返回到 5.0 时它停止工作（我可以启动，但 ubuntu 没有检测到任何 nvidia 正在运行）。
我没什么办法了（除了重新安装整个操作系统），所以我希望有人能帮助我诊断出发生了什么变化并让它再次工作......
谢谢！

更新 2：根据@Marmayogi 的建议，/lib/modprobe.d/blacklist-nvidia.conf包含以下内容：
# Do not modify
# This file was generated by nvidia-prime
blacklist nvidia
blacklist nvidia-drm
blacklist nvidia-modeset
alias nvidia off
alias nvidia-drm off
alias nvidia-modeset off
