I’m using driver 470 on Ubuntu 21.10 with Geforce 2060 Super
launch sudo nvidia-settings
Go to X Server Display Configuration to change frame rate to 75 Hz
Click on apply
Save ro X configuration file
But have this : unable to open X config file ‘/etc/X11/xorg.conf for writing’
In terminal have this
$ sudo nvidia-settings
[sudo] :

Package xorg-server was not found in the pkg-config search path.
Perhaps you should add the directory containing `xorg-server.pc'
to the PKG_CONFIG_PATH environment variable
No package 'xorg-server' found
Error executing /usr/share/screen-resolution-extra/nvidia-polkit: Permission denied
