Gnome-shell-system-monitor-applet: Fan display incorrectly asks me to install lm-sensors

[protist]

In in the settings window, the fan tab asks me to Please install lm-sensors. This is already installed, (and thermal monitoring works). I suspect the problem is that my computer is incapable of showing fan speeds, because running $ sensors in the command line only shows information about temperature. I suppose the error-checking and error-reporting are at fault here.

Cheers.

Also, package in Arch Linux is called lm_sensors, not lm-. But I don't know how it's called in another distros.

I have Arch Linux and lm_sensors installed. The problem seems to be that, by default, fan sensors are not configured.

sudo sensors-detect

and following the instructions solved me the problem.
