Just try to make it very simple,
The following steps will only be possible after installing a proper nvidia driver from the default repository or the bash file from the official Nvidia website,
Open terminal,
Type: sudo nvidia-xconfig --enable-all-gpus
You can add: option "coolbits" "12" to the device section
To /etc/X11/xorg.conf file, to enable fan or overclock on the Nvidia x server settings gui
Happy mining
