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.

The settings in the nvidia-settings tool cannot be saved, however, without starting the tool as root and doing all kinds of workarounds which is impossible to do for the average user. Do you really expect users to reconfigure their displays after every login? Unless you can fix this, the Nvidia driver recommendation should simply be removed. Delivering such a horrible experience to millions of users seems like a bad joke and the persons responsible should feel really bad about this. Ubuntu has no future anywhere with such usability issues.
