呵呵，就按照上面的网址，就完全解决了。
如果有人遇到这样的问题，也按照这个办法解决就可以了。
将过程贴到下面，方便大家查询。
Step 1. Install the thinkfan software and the sensors:
sudo apt-get install thinkfan lm-sensors
Step 2. Make sure that the daemon controls the fan by editting the thinkpad.conf file:
sudo nano /etc/modprobe.d/thinkfan.conf
by adding the following line:
options thinkpad_acpi fan_control=1
Step 3. Make the daemon load automatically at start-up by editting the file:
sudo nano /etc/default/thinkfan
making sure that the START key is set to yes, i.e. there should be a line that says:
START=yes
Step 4. Detect your laptop's sensors:
sudo sensors-detect
and just choose the default answers whenever you're prompted by hitting Enter.
Step 5. Load the new modules. From ubuntu 13.10 this done by:
sudo service kmod start
while for previous versions like 13.04 you instead will need to do:
sudo service module-init-tools start
Step 6. Figure out which sensors are in use:
sensors
(the ones that indicate 0 degrees are not in use, I don't know why those are "detected" too). Remember which ones are in use.
Step 7. Find out the full paths of these sensors:
find /sys/devices -type f -name "temp*_input"
The output should be a list of paths like /sys/devices/...
Step 8. Copy-paste the paths to the sensors into the configuration file /etc/thinkpad.conf. To do this, first open up the file:
sudo nano /etc/thinkfan.conf
There should already be a line like
#sensor /proc/acpi/ibm/thermal (0, 10, 15, 2, 10, 5, 0, 3, 0, 3)
(the #-symbol means that that line is commented out). Add a line starting with sensor (without the #-symbol) and copy-paste you first sensor. Repeat this if you have more than one sensor. For example, on my machine, the output in step 7 yields
/sys/devices/virtual/hwmon/hwmon0/temp1_input
/sys/devices/platform/thinkpad_hwmon/temp3_input
/sys/devices/platform/thinkpad_hwmon/temp4_input
/sys/devices/platform/thinkpad_hwmon/temp5_input
/sys/devices/platform/thinkpad_hwmon/temp6_input
/sys/devices/platform/thinkpad_hwmon/temp7_input
/sys/devices/platform/thinkpad_hwmon/temp1_input
/sys/devices/platform/thinkpad_hwmon/temp8_input
/sys/devices/platform/thinkpad_hwmon/temp2_input
/sys/devices/platform/coretemp.0/temp4_input
/sys/devices/platform/coretemp.0/temp2_input
The ones that are in use in my machine are the ones in the first and the last two lines, so I added the three lines:
sensor /sys/devices/virtual/hwmon/hwmon0/temp1_input
sensor /sys/devices/platform/coretemp.0/temp4_input
sensor /sys/devices/platform/coretemp.0/temp2_input
Step 9. Finally we can set the fan speed levels in the configuration file. Open the /etc/thinkpad.conf file if it wasn't open already.
sudo nano /etc/thinkfan.conf
The fan levels I use on my ThinkPad x201 are:
(0, 0, 51)
(1, 50, 52)
(2, 51, 55)
(3, 54, 58)
(4, 56, 63)
(5, 60, 70)
(6, 66, 79)
(7, 74, 92)
(127, 85, 32767)
The last line ensures full fan speed (127 = "disengaged" i.e. unregulated). You can fiddle with these levels to fit your needs/wishes, but PLEASE BE CAREFUL!
For those people out there familiar with Mathematica, I wrote a short notebook to generate these fan speed values.
Step 10. Reboot. Everything should work now. In order to check whether thinkpad is runnning correctly, use
sudo thinkfan -n
which starts thinkfan in verbose mode. You might want to stop the thinkfan daemon first:
sudo /etc/init.d/thinkfan stop
If you want to start the thinkfan daemon again, type:
sudo /etc/init.d/thinkfan start
Just to be complete, my /etc/thinkfan.conf configuration file is:
# IMPORTANT:
#
# To keep your HD from overheating, you have to specify a correction value for
# the sensor that has the HD's temperature. You need to do this because
# thinkfan uses only the highest temperature it can find in the system, and
# that'll most likely never be your HD, as most HDs are already out of spec
# when they reach 55 °C.
# Correction values are applied from left to right in the same order as the
# temperatures are read from the file.
#
# For example:
# sensor /proc/acpi/ibm/thermal (0, 0, 10)
# will add a fixed value of 10 °C the 3rd value read from that file. Check out
# http://www.thinkwiki.org/wiki/Thermal_Sensors to find out how much you may
# want to add to certain temperatures.
# Syntax:
# (LEVEL, LOW, HIGH)
# LEVEL is the fan level to use (0-7 with thinkpad_acpi)
# LOW is the temperature at which to step down to the previous level
# HIGH is the temperature at which to step up to the next level
# All numbers are integers.
#
# I use this on my T61p:
#sensor /proc/acpi/ibm/thermal (0, 10, 15, 2, 10, 5, 0, 3, 0, 3)
#(0, 0, 55)
#(1, 48, 60)
#(2, 50, 61)
#(3, 52, 63)
#(4, 56, 65)
#(5, 59, 66)
#(7, 63, 32767)
# My settings for my ThinkPad X201: (kris)
sensor /sys/devices/virtual/hwmon/hwmon0/temp1_input
sensor /sys/devices/platform/coretemp.0/temp4_input
sensor /sys/devices/platform/coretemp.0/temp2_input
(0, 0, 51)
(1, 50, 52)
(2, 51, 55)
(3, 54, 58)
(4, 56, 63)
(5, 60, 70)
(6, 66, 79)
(7, 74, 92)
(127, 85, 32767) |
