I have a thinkpad x390 yoga and I can't seem to control or read the fan speed, I have a gui installed for thinkfan and when I click "full_speed" I get an error : (please check that /etc/modprobe.d/thinkpad_acpi.conf contains "options thinkpad_acpi fan_control=1").
I have checked that file and it has that line, so I'm not sure what to do.
