can it work if I use iGPU to display? about nvfancontrol HOT 4 CLOSED

The short answer is: no. nvfancontrol uses the same infrastructure as nvidia-settings and that requires an X server attached to the display.

The long answer is: maybe if you are willing to experiment. Since you installed the driver with --no-opengl-files there is a chance xvfb might help. First you probably need to add Option "AllowEmptyInitialConfiguration" to the 20-nvidia.conf file in addition to the existing options is Section "Device". Then you may be able to use xvfb-run to start nvfancontrol with a command similar to (you might need to adjust the server options; see the manpage).

xvfb-run -a -s "-screen 0 640x480x24 +extension RANDR" -- ./nvfancontrol -d

If this does not work you might need to "fake" a screen. There is a detailed guide if you are willing to try!

Thanks for your answering. If I install nvidia driver with opengl component, and then use prime-select intel to swith to iGPU for displaying. In this case, I found I couldn't nvidia-settings anymore. Do you know how to solve it? Thanks anyway。

In that case if the xvfb-run method doesn't work then probably the only other way would be to fake a screen using the guide I linked.
