16.04 is old at this point. I had a similar problem with Ubuntu 22.04, which should be currently supported, and found a solution on that release. I am using a fully patched system with nvidia-settings 510.47.03-0ubuntu1. It needs to be able to write /etc/X11/xorg.conf when running as root when the user requests it. Attempting to run nvidia-settings as root it cannot write to that configuration file. The following change fixed this for me: chmod u+x /usr/share/screen-resolution-extra/nvidia-polkit Please update the package to implement the equivalent and close this.
