我刚刚在我的 2021 Acer Nitro 5 上安装了 Ubuntu 22.04.1 LTS。问题是 Nvidia gpu 不工作。
我通过“附加驱动程序”面板安装了驱动程序，并选择了非 Nouveau 版本（实际上我尝试了所有版本，包括从 475 到 525 的开放内核和服务器）；实际上我正在运行nvidia-driver-525 (proprietary)
如果我打开 nvidia-smi，我会出现以下错误NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.。
与 nvidia-settings 相同：ERROR: NVIDIA driver is not loaded
奇怪的是，我在另一个驱动器上安装了 Ubuntu 22.04，并且 Nvidia 运行正常，但现在当我重新安装它时，它却不工作了。
我也禁用了安全启动，并尝试使用最新的内核头重新安装；我也已经检查了所有的解决方案，但对我来说不起作用。
GPU 是 GTX 1650 Ti Mobile。CPU：i5-10300H
我在这里先向您的帮助表示感谢

您已将nvidia模块列入黑名单/lib/modprobe.d/blacklist-nvidia.conf。
该文件现在未被使用，可能是由从 PPA 安装的某些软件添加的。
删除此文件
sudo rm /lib/modprobe.d/blacklist-nvidia.conf
然后重新启动。
