The instructions here solved my problem: https://www.programmersought.com/article/45694457131/
There seemed to be a missing symlink to the nvidia-polkit python file: 1. cd /usr/share/screen-resolution-extra && ls 2. sudo ln -s nvidia-polkit.py nvidia-polkit 3. sudo chmod +x nvidia-polkit Also, ensure that the system is using python 3: 4. sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 100 5. sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 150 6. sudo update-alternatives --display python I can confirm that after I ran 1-6, then ran $ nvidia-settings, I was able to successfully save my X-config file, and then reboot, with the settings loading automatically during reboot. Note that updating the default python version may break things that assume `which python` == `which python2` (e.g. terminator) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1822937 Title: NVIDIA settings won't write to /etc/xorg To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-settings/+bug/1822937/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
