Okay; I think I have a partial solution. To do this you need acpi and powersaved, both installed from Synaptic; it is assumed you are running Karmic 9.10. Once installed, proceed as follows:
1) Open Terminal and enter the following code:
Code:
/proc/acpi/thermal_zone/*/trip_points
and compare with
This will tell you your "trip points," the Celsius temperatures where the fan kicks in ("active"), where the processor slows itself down ("passive"), and where it gets so hot it shuts down the system completely ("critical"). The simple solution would be to lower all these variables by at least 10 degrees; unfortunately, if you have the same luck I did acpi won't let you do that.
2) Whether you're able to override the trip points or not, first check the following:
Code:
/proc/acpi/thermal_zone/*/cooling_mode
If this document exists, then you can alter Cooling Mode in powersave. If not, skip to step 6.
3) Next type:
Code:
sudo gedit /etc/powersave/thermal
When gedit opens the document, find the non-hashed line that reads ENABLE_THERMAL_MANAGEMENT="" and alter as shown below:
Code:
ENABLE_THERMAL_MANAGEMENT="yes"
Exit gedit.
4) Repeat of step 3 with a different document:
Code:
sudo gedit /etc/powersave/scheme_powersave
Scroll down to the non-hashed line COOLING_POLICY="passive". Change to:
Code:
COOLING_POLICY="active"
Exit gedit.
5) Reboot the system to enact changes.
I have no idea how well this will work; honestly it doesn't seem to be doing much for me. My processor reads in the ninety-degree range (about 200 Farenheit!) either way.
6) Open this document (this will only work if powersave is installed):
file:///usr/share/doc/powersaved/html/Thermal.html
This is a chapter of the powersave manual; it basically tells you how to do everything I just said, except it also tells you how to override the trip points. That said, I couldn't find a line anywhere in powersave's /scheme_* files with THERMAL at the beginning. I don't know if you're supposed to add it in yourself or what; they don't explain it very well. It does say to e-mail your vendor for the trip point settings used by BIOS -- which is sensible since in most of these cases the fan worked a lot better with Windows.
-----
If anyone figures out step 6, kindly add what you did on to this thread; it means you had better luck than I did. I know those trip points are the key; I just can't figure out how to get the system to let me change them. Good luck to all of you!
