Lubuntu 20.04, Nvidia drivers installed, yet NVIDIA-SMI states it can't connect to driver
I followed the additional drivers prompt to install nvidia 440 drivers, they do show as installed. However the SMI output shows that it can't connect and acts as if it is either not installed or not running. prime-select query shows it is set to nvidia and i did attempt to swap the prime select to intel and then back to nvidia and ran a full reboot without any fix to the problem.
dpkg output for nvidia shows I have everything.

Потратив некоторое время на изучение этого вопроса, прежде чем спрашивать, но я определил, что наилучшая методология, вероятно, будет заключаться в очистке всех файлов драйвера nvidia через
sudo apt remove --purge '^nvidia-.*'
, а затем после установки CLI
sudo ubuntu-drivers autoinstall
sudo apt install nvidia-driver-440
. снова запустил nvidia-settings и фактически получил желаемый вывод, а не кучу ошибок, утверждающих, что драйвер не найден.
