- this sets the fan controls to auto. Then it follows the settings defined in /proc/acpi/thermal_zone/THRM/trip_points on when to activate one fan or both.
If you do not have these files, it is not compiled in. Also, there is a chance you do not have the sensors enabled. It is not a very useful thing if the fans are set to go off at a certain temperature, and the system insists it is 0 degrees.
Im almost completely new to Linux, and I have been having this problem...
Although, my /proc/acpi/fan directory is empty...so by this logic it isn't compiled in. I was wondering how do you do this, or what kind of modules can you use to remedy this? I've tried using lm-sensors with (seemingly) no luck. Maybe I'm way off...
Anyway, Im using a Compal Cl56 Laptop and running Ubuntu 5.10 (Breezy).
