NVidia Driver 450 not loaded on Ubuntu 18.04


I am having issues with my NVidia Drivers 450 on Ubuntu 18.04. I have a dual boot Ubuntu and Windows 10.

I don’t manage to load my NVidia GPU, even if prime-select says it is loaded.

~$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M1000M] (rev a2)

~$ sudo prime-select nvidia
Info: the nvidia profile is already set

~$ nvidia-settings

ERROR: NVIDIA driver is not loaded

ERROR: Unable to load info from any available system

I’ve been tried different solutions found on this forum but none appears to solve my problem :

  • remove blacklist-nvidia.conf (doesn’t exist)
  • remove secure boot
  • reinstall drivers

Here is my nvidia bug report.

Thanks for your help.
