NVIDIA-SMI driver problem on Ubuntu 18.04

Hello, I have nvidia driver 440 on ubuntu 18.04.
I had no problem with that version. Ive updated ubuntu from 16 to 18 recently

NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

I have Windows and Ubuntu on my computer. Secure boot is disabled. Legacy/UEFI mode is used on my MSI gf 630 laptop.
