nvidia-settings cannot save to xorg.conf, apply this fix
If you’re using ubuntu and having trouble with nvidia-settings saving to the /etc/X11/xorg.conf file, you may find the following tip helpful in relieving that annoyance. Looking for something interesting when I login to one of my servers, I decided to whip up the following script I appended to my ~/.bashrc file.
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
sudo gedit /etc/X11/xorg.conf
paste the following:
Identifier “Configured Video Device”
save and close.
back to terminal:
and save the file.
