nvidia reseting settings for main monitor after disconnecting second monitor
how i prevent that?

Please, with both monitors attached, post the output of inxi -Fzxx so we can see the config and how the system recognizes the monitors.

update:

sorry for long time reply but i don’t have old monitor now

after thousand of reboots and trying to change hz
i changed monitor hz in gnome settings now i can launch wayland but on xorg error persist

on wayland nvidia settings showing gpu correctly

and when i start some electron app it showing gpu: GRAPHICS: GPU0: GP107 [GeForce GTX 1050 Ti] VRAM: 32MB

and when i reboot perfomance changing, like: i try to launch some game it showing 80fps and after reboot its 200fps

and when i login in 1 second it showing input not supported and then gnome desktop loads on wayland

and when i shutdown/reboot/logout error appear, and sometimes when i shutdown/reboot fedora shutted down but fans continue spinning and led working and motherboard doesnt react on reset/shutdown buttons and error showing

and when fedora boot up there is [FAILED] nvidia-powerd.service but i think its because of missing xorg-x11-drv-nvidia-cuda

notes:
and note that i dont install xorg-x11-drv-nvidia-cuda because error will appear,
i upgraded fedora from 36 > 37 and kernel from 5 > 6,
nvidia driver from rpmfusion,

Specifically what error appears.?
We need the exact message you see on the screen to determine the cause and assist in repair.

Please do dnf install xorg-x11-drv-nvidia-cuda and show us the command and all the text following.

It would also be helpful to see the output of
dnf list installed '*nvidia*' and lsmod | grep nvidia.

That inxi output shows you are using Wayland and that the nvidia driver may not be in use. Have you tried using xorg to see if there may be a difference?
Sometimes things work in xorg and not wayland, and vice versa.

xorg-x11-drv-nvidia actually installed but nvidia-smi command not found so i upgraded xorg-x11-drv-nvidia and now nvidia-smi working but input not supported error still on Gnome on xorg persist, sorry for misunderstanding

i mentioned that with Gnome on wayland driver works but in Gnome on Xorg, input not suported error persist so i cant enter Gnome on Xorg, i want to use Gnome on xorg because nvidia support for wayland is buggy

output of dnf list installed '*nvidia*'

and what is correct /etc/X11/xorg.conf here is current monitor config

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName	  "Acer SA230"
    HorizSync       55.0 - 60.0
    VertRefresh     50.0 - 60.0
EndSection

What is correct Horizsync and VertRefresh for 60hz?

notes:
input not supported is acer monitor error not fedora or nvidia,

This is not the version of nvidia installed from rpmfusion on my system.
This is what is installed from rpmfusion on all my systems and I never have version mismatches.

| NVIDIA-SMI 525.78.01    Driver Version: 525.78.01    

It would appear you may be installing nvidia from nvidia or at least from different sources so the version mismatches occur.

Please post the output of dnf list installed '*nvidia*' again.

With installing nvidia drivers from rpmfusion the /etc/X11/xorg.conf file is not used at all. (does not even exist on any of my systems)

For me to assist in a way I am comfortable with I would assist in removing the drivers you currently have and then installing the drivers from the rpmfusion repo.

EDIT.
I just ran dnf upgrade *nvidia* --refresh and it picked up the 525.85.05 packages, so it seems I was a bit delayed in seeing the upgrade.

That said, it would seem that you could possibly remove the /etc/x11/xorg.conf file you presently have and the drivers should probably work out the monitor issue for you automatically.

Please post back here and let us know how that works out for you.

i removed /etc/X11/xorg.conf as you said, but nothing has changed still can’t login to Gnome on xorg because of input not supported only Gnome on wayland works

and i run ls in /etc/X11/ and there is some nvidia files, is this ok?

applnk  fontpath.d  xinit  Xmodmap  xorg.conf.backup  xorg.conf.d  xorg.conf.nvidia_uninstalled  Xresources  Xsession.d  Xwrapper.config

and in the past when i owned old monitor and old monitor and current are attached i logged in Gnome on xorg and with old monitor, opened nvidia-settings changed current monitor hz and there is save to xorg.conf and save buttons, so i click on save to xorg and /etc/X11/xorg.conf generated, and as i mentioned when i click save button, current monitor start working but after disconnecting old monitor, current monitor hz resets back to 75hz

notes:
in the past with old monitor only connected it works fine, but with my current monitor only connected Gnome on xorg not working so it might be acer problem if so why wayland works but xorg not?,

and in wayland nvidia-settings cant control monitor refresh rate and screen resolution, but in Gnome on xorg monitor refresh rate and screen resolution was controlled by nvidia-settings so does nvidia-settings config file exist if yes, where?

Without knowing the content of that file I cannot answer, but it does not exist on my system.

# ls /etc/X11
applnk  fontpath.d  xinit  Xmodmap  xorg.conf.d  Xresources  Xsession.d  Xsession.options  Xwrapper.config

Seemingly you may have installed nividia from some location other than rpmfusion in the past and invalid config files certainly can impact performance.

I only have a few files related to nvidia.
/etc/X11/xorg.conf.d/nvidia.conf
/etc/modprobe.d/{nvidia.conf,nvidia-installer-disable-nouveau.conf}

The one under /etc/X11/xorg.conf is one that was put in on my laptop to make the nvidia dGPU play nice with the laptop screen as well as external monitors and to use the dGPU as primary full time.
The other 2 were installed when I installed or upgraded the nvidia drivers so they were part of the nvidia install from rpmfusion.

I also only have this in /etc/default/grub that was added to that file during the nvidia install
rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvidia-drm.modeset=1 initcall_blacklist=simpledrm_platform_driver_init which was added into the GRUB_CMDLINE_LINUX= part of that file.

i dont install nvidia driver from other location, i only reinstalled nvidia-driver from rpmfusion

there is content of /etc/x11/xorg.conf.nvidia_uninstalled:

maybe its backup of /etc/X11/xorg.conf?

and there is a way to login in Gnome on Xorg with safe graphics? or change nvidia-settings refresh rate with wayland or config file?, because on wayland there is no monitors in nvidia-settings

update1:
and i installed i3wm and without /etc/X11/xorg.conf there is input not supported error with /etc/X11/xorg.conf it works! so maybe it problem with gnome? there is any gnome xorg configuration if yes where? and i tried to change nvidia-settings refresh rate in i3wm on i3 it changing but, config from i3wm not moving to Gnome on Xorg or not working

update2:
i installed kde plasma logged in Plasma (wayland) without nvidia drivers, changed refresh rate in system settings 75 > 60 restarted fedora with nvidia drivers, logged in Plasma (x11) and it works! and looks like refresh rate on i3wm and plasma changing but not changing in Gnome on xorg why? and this trick does not working on Gnome on Xorg

update3:
and refresh rate on i3wm and kde plasma is not the same looks like nvidia changing settings for only current desktop enirvoment how do i make nvidia-settings settings global?
