Environments:Nvidia Jetson Nx;JetPack 4.4.1
The fan can’t work automatically before logging in the graphical interface,and it can work well in manual mode.
How can I set it can make it work well as the manual mode before login?

hello blstcvLiu,

please refer to developer guide for the Fan Mode Control session.
it’ll by default turns on the fan when the temperature rises above the trip point.
you may have customization by setting the default fan mode within nvpmodel.conf.
thanks
