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?
