Xorg.conf doesn't work

Question

I'm trying to save my resolution/refresh rate configuration using the "Save to X Configuration File" option in Nvidia X Server Settings. It generates a xorg.conf file in /etc/X11 directory. Here is the xorg.conf:

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 367.35  (buildd@lgw01-18)  Tue Aug  9 10:11:49 UTC 2016

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 375.66  (buildmeister@swio-display-x86-rhel47-06)  Mon May  1 15:45:32 PDT 2017

    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

How we can see in Section "Screen", I have this line:

 Option         "metamodes" "1920x1080_60_2 +0+0"

But every time I reboot my computer (OS: Ubuntu 17.04 LTS), the resolution and the refresh rate is set to "auto". This "_60_2" metamode makes difference to me, then I want to know how can I make it(xorg.conf) work.

As we have chat, sometime prime don't support set refresh rate.

Do I save this ".nvidia-settings-rc" in the same directory of xorg.conf? – João Victor Sep 26 '17 at 03:29
I save .nvidia-setting-rc in home dir and xorg.conf in /etc/X11 dir – Aravind Sep 26 '17 at 03:31
Try not to change the dir that it suggest. – Aravind Sep 26 '17 at 03:32
Ok, I tried it. Unfortunately it did not work. I checked if the hidden file was in the home and if the xorg was in the etc / X11 as described above and configured. When the computer started the refresh rate and resolution was "auto". Thank you for trying. – João Victor Sep 26 '17 at 03:41
goto dash >logs > important tab. Are you getting some error related to nvidia here? – Aravind Sep 26 '17 at 03:45
Yes. I have this: Sep 26 00:44:19 joao-desktop nvidia-settings[3923]: PRIME: No offloading required. Abort Sep 26 00:44:19 joao-desktop nvidia-settings[3923]: PRIME: is it supported? no – João Victor Sep 26 '17 at 03:47
I don't know if is what you're looking for... – João Victor Sep 26 '17 at 03:49
