Nvidia update problems

After updating my video driver I am having problems with various sites. I found the following in the 'syslog' :

Jul 20 08:21:05 william-FK522AA-ABA-a6544f kernel: [609500.858664] NVRM: API mismatch: the client has the version 390.77, but

Jul 20 08:21:05 william-FK522AA-ABA-a6544f kernel: [609500.858664] NVRM: components have the same version.

Also the 'Nvidia X Server Settings' application is not working. What do I need to do to correct this issue?

Purge all of the nvidia stuff first:

sudo apt purge ^nvidia

Install recommended Ubuntu Nvidia driver:

sudo ubuntu-drivers autoinstall

Reboot:

sudo reboot

After reboot check Nvidia driver in use:

nvidia-smi

Remark. If your Nvidia card is supported by 396 version nvidia driver, consider installing it from Proprietary GPU Drivers repository. Just execute before nvidia drivers clean up:

sudo add-apt-repository --remove ppa:graphics-drivers/ppa
sudo apt update
