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.

dieuweI have an Optimus laptop, a Dell XPS 15 L502, which I've had for a few years and have tried various things on (bumblebee, nvidia-prime, linux kernel optimus support).

I don't use ppa. I installed the driver using "Additional Drivers" option in my Ubuntu.
Is this nvidia_prime necessary to do what I want?

No. prime just offers you to edit setting via GUI. Like whether you want use nvidia high performance or intel driver for power saving etx.

Your English is then mine.
Let me study and I will come back to you. I think prime don't save these setting automatically. I think, I have to find a manual way.
I think we have to do it via terminal as per this article

Q: How to see/change screen refresh rate or monitor frequency?

HappyDeveloperMy eyes hurt so I thought I should check the screen refresh rate (monitor frequency), but I couldn't find it. Where is it? (in Ubuntu 12)

Yes. This last article is what I do actualy.
I just thought that is a best way to do it. Because it works only after I login in a user account and it becomes the initialization slowly.
But I think I'll keep this solution and learn to live with it.
I have to leave. It's getting late here. Thank you for your time.
