Please install the 470 legacy driver from repo and delete /etc/X11/xorg.conf

Installed and del xorg.conf

I think all work, but why glxgears show low framerate?

Because it’s locked to vsync. You have a 60Hz display.
Please also delete /usr/share/X11/xorg.conf.d/10-nvidia.conf
The mode is handled by prime-select, if you set “PrimaryGpu” manually, you’ll run into problems.
