Hi, I have a problem when I type 'sudo nvidia-settings' then go to 'X Server Display Configuration' then click 'Advanced' and then check 'Force Full Composition Pipeline'. After I hit apply It works well to prevent screen tearing but when I click on ' Save to X Configuration File' and then 'Save' it gives me the error 'Unable to open X config file " for writing.'
Where is this file or do I need to create it in /etc/X11/xorg.conf.d? I'm running a gtx1060 with nvidia driver version 390.25.
