What screen res is it set on in the nvidia gui and also what one's does it list as options you can change it to?

Also have you tried running the nvidia gui as/with superuser/root permission?

As it sounds to me like, as far as the nvidia driver is concerned you have done it! But something is once again changing it back or causing the nvidia driver to.

Hang on, try deleting ~/.nvidia-settings-rc as it might be looking at that and getting confused.

Hey again, I really thought that was it then.... It made perfect sense to delete the nvidia settings file but unfortunately it still didnt help. Around 3 seconds after login the screen res changed to 4k still

i have tried under root and my user.

hmm, as I said before, from what you were saying before, it really sounds to me like, something is changing your screen res after you login to what I'm assuming is your 'everyday' user account.

IS there any other options in the nvidia gui other than 4k?

IS the nvidia gui the ONLY place (other than the nvidia-xconfig commands/xorg.conf) you have tried to change your screen res?

IS there any other places that you can change your screen res in your distro?

As the only other issue I can think of is that you have set it somewhere OTHER than xorg.conf or the nvidia gui and therefore it's reverting to that.

I did not have to do anything else other than the nvidia-xconfig commands on mine and this worked. So I'm really running out of ideas for ya.

Edit: does your hardware support the screen res you are trying to change it to (I don't think this is the issue but, still worth checking out anyways)?

I thought it was light DM changing this. I am using Linux Mint and Lightdm has no settings.

There are a lot of screen resolutions in the Nvidia GUI.... Nearly all resolutions, the only native is 4k, the rest say scaled.

The only places I have edited Resolutions is the Nvidia GUI, nvidia commands, xorg.conf and also the native linux mint display gui which only have 4k as a choice.

I cant find anywhere in my distro other than nvidia and native display app.

I do appriciate all your attempts to help me. Its so frustrating.

I guess I could write a script like xrandr --output DVI-D-0 --mode 1920x1080 to run after login if I have to.

Or maybe check some logs but dont know which ones.

Yes my hardware supports 1080p.

I can't say this is the case for sure but, if the "mint display gui" only has 4k as a choice, this *might* be a clue and/or the reason your screen res keeps going back to 4k?

I will run Mint in a virtual machine for ya and have a look. And hopefully we can solve this for ya!

Hey buddie, I really appreciate all this. Very grateful.

That's cool.

As I only have an ISO for the KDE version of Linux Mint, what is the exact name of the "mint display gui" and also is it a part of the desktop environment you are using?

Hi, I am using mint 18.1 with cinnamon.

my only 1 issue with it is this 4k problem.

yes, but is the "mint display gui" you were talking about before a part of the desktop environment if that makes sense (and what is it's exact name)?

Hi, not sure if you can make sense of this but this guy is having same problem and it seems like the desktop overiding nvidia..

https://github.com/linuxmint/Cinnamon/issues/4971

Yep, exactly what we were thinking, it looks like the cinnamon-settings display tool is overriding xorg.conf Good looking!

This is why I was asking you for the name of cinnamon-settings display tool, as I wanted to see if there is any setting in there that would stop it overriding xorg.conf

its just called display

yeah that's ok, I use the KDE desktop environment myself and therefore am not familar with the cinnamon desktop environment (not your fault, mind you ).

Is there any setting you can see to disable using the the cinnamon-settings display tool in terms of your screen res/in general?

Hi, no there is nothing in there for disabling it. I am happy to move away from cinnamon desktop as long as i can be sure it will work...
