Okay, I need to update my first post. Seeing some strange nvidia leftover package, I tried to remove it and did 2 other tentatives:
- manually install the 470 on 4.5 and 4.2 kernels
- ubuntu official method with 535 and the same kernels
With both, I can’t boot on the 4.5 kernel but it works with 4.2 kernel.
nvidia-driver-470
nvidia-settings
warned me about this:
ERROR: nvidia-settings could not find the registry key file or the X server is not accessible. This file should have been installed along with this driver at
/usr/share/nvidia/nvidia-application-profiles-key-documentation. The application profiles will continue to work, but values cannot be prepopulated or validated, and will not be listed in the help text.
Please see the README for possible values and descriptions.
I followed this solution: ERROR: nvidia-settings could not find the registry key file - #3 by geoffrey.hoffman
There is a strange message but it seems okay (see: PRIME not supported after installing nvidia-driver-470 for Ubuntu 20.04 LTS):
$ nvidia-settings
[...]
** Message: 10:19:04.177: PRIME: No offloading required. Abort
** Message: 10:19:04.177: PRIME: is it supported? no
$ nvidia-smi

Well in /var/log/kern.log
I got:

I tried this
sudo dkms remove nvidia/470.239.06 --all
sudo dkms --force install nvidia/470.239.06 -k 6.2.0-39-generic
But even after a reboot, the same error appears.

With the ubuntu-drivers tool, this is what I get:
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
