Nvidia对他们的安装做了一些改动。

现在，Nvidia库位于/usr/lib/x86_-linux-gnu中 blacklist-nvidia.conf文件位于/lib/modprobe.d/中在blacklist-nvidia.conf中，仍然存在未经注释的 alias nvidia off。

注释掉

alias nvidia off

后，如图所示:

```bash $ cat /lib/modprobe.d/blacklist-nvidia.conf# Do not modify# This file was generated by nvidia-primeblacklist nvidiablacklist nvidia-drmblacklist nvidia-modeset#alias nvidia offalias nvidia-drm off
