Nvidia Setting is not available after installation

Hello,
I've installed Zorin Pro OS. Nvidia drivers were installed during installation process. I can see it in additional drivers setting but when i want run nvidia-settings i can't see anything


I want to be sure if on-demand mode is enabled.
Someone can help?
Thanks,

Have you tapped alt+F2 and then entered into it, nvidia-settings and hit the enter key?

Effect is the same :frowning:

It works here, and I am using the x-swat teams updates...
Let's see if that helps you any:

sudo add-apt-repository ppa:ubuntu-x-swat/updates

sudo apt update && sudo apt upgrade

Reboot and test...
