I've installed a fancontrol script from the Ubuntu repository, and modified it a little because of problems I've had with it (sometimes it would act like the config is wrong when it would in fact work if it just ignored the issues, and sometimes the problem would be solved by running a modprobe command which it could actually do by itself). I've attempted to set up a script to run it as a daemon at startup, with admin privileges and all so it can modify the PWM settings, but that didn't work. When I try to run "sudo /etc/init.d/fancontrol start" it returns " * Starting fancontrol daemon... [ OK ] " but the fancontrol process isn't present, and the fans are still at full speed.
When I start it manually (sudo fancontrol), it works okay.
I've now tried to reinstall it, thereby undoing all my modifications. But the daemon problem persists.
The tutorial I used to try and get this working is this: http://ubuntuforums.org/showthread.php?t=42737
Except I used the version from the package manager.
My fancontrol (at /usr/sbin/fancontrol) script looks like this, after being reinstalled:
Code: Select all
#!/bin/bash
#
# Simple script implementing a temperature dependent fan speed control
# Supported Linux kernel versions: 2.6.5 and later
#
# Version 0.70
#
# Usage: fancontrol [CONFIGFILE]
#
# Dependencies:
# bash, egrep, sed, cut, sleep, readlink, lm_sensors :)
#
# Please send any questions, comments or success stories to
# marius.reiner@hdev.de
# Thanks!
#
# For configuration instructions and warnings please see fancontrol.txt, which
# can be found in the doc/ directory or at the website mentioned above.
