我尝试了迄今为止我所知道的所有方法，但没有办法执行nvidia-smi。
这是我的 GPU：
$ sudo ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd00001C81sv00001043sd0000203Bbc03sc00i00
vendor : NVIDIA Corporation
model : GP107 [GeForce GTX 1050]
driver : nvidia-driver-390 - distro non-free
driver : nvidia-driver-435 - distro non-free
driver : nvidia-driver-430 - distro non-free
driver : nvidia-driver-440 - third-party free recommended
driver : xserver-xorg-video-nouveau - distro free builtin
nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
我已经安装了：
$ apt search nvidia-driver
nvidia-driver-440/unknown,now 440.33.01-0ubuntu1 amd64 [installed]
NVIDIA driver metapackage
xserver-xorg-video-nvidia-440/unknown,now 440.33.01-0ubuntu1 amd64 [installed,automatic]
NVIDIA binary Xorg driver
另外（这真的很糟糕）我只可以选择将屏幕设置为 800x600 :(
谁能帮我？
