我安装的 nvidia-440 驱动程序（我的系统推荐的驱动程序）似乎运行正常，但我的系统拒绝实际跑步它。我使用它安装了它sudo ubuntu-drivers autoinstall并且一切都检查无误。
$ prime-select query
nvidia
$ sudo apt list --installed | grep "nvidia*"

这是我的特定系统设备：

但当我检查时，我看到的是这样的：

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

我的计算机似乎仍在使用我的英特尔卡：

我已经编辑了 grub，禁用了 nouveau 和 wayland，几乎做了我能想到的所有事情。你能帮助我吗？
