I am unable to use netiher nvidia-smi nor nvidia-settings:
~$ 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.
~$ nvidia-settings
ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system
(nvidia-settings:1934090): GLib-GObject-CRITICAL **: 13:08:27.196: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

I have tried installing multiple versions of the nvidia-driver (340, 390, 430, 440, 450, 455, 460, 465, 470), both from the official packages and from the grapühics-drivers ppa. with all versions the problem was the same, only 340 and 390 made my screen stay black when the login screen should appear.
