Hi,
I have a question related to lm-sensors and in particular fan control.
I've tried to find
a solution in many places online but with no luck, I think the people
at
lm-sensors will be the last place I look.
I recently installed Ubuntu Karmic 9.10 (dual boot) on a Vista Acer
Aspire 3810t laptop. Processor and chipset specs are:
-
* - Intel® Core™2 Solo ultra low voltage processor SU3500
* - Mobile Intel® GS45 Express Chipset
Power:
* ACPI 3.0 CPU power management standard: supports Standby and
Hibernation power-saving modes, 62.16 W 5600 mAh 6-cell Li-ion
battery pack: Acer PowerSmart 3-pin 65 W AC adapter, ENERGY
STAR® 5.0

Under Ubuntu 9.10 there appears to be a significant increase in the
fan
operation. Both when the laptop is plugged in and unplugged the fans
operate almost
constantly and at a strong speed. Since this did not happen under
Vista
and is quite bothersome, I started looking around for a solution.
I installed the "Sensors Applet on the gnome panel" but that only
gives
me temperature readouts (the Core0 temp is always around 41 C, with
the
fan spinning all the time).
I then installed "coretemp" through Synaptic, "lm-sensors", ran
"sensors-detect" (I have pasted the output of sensors-detect after the
end of the email as it is quite long). After that I ran "sensors" on
the
Terminal. This is what I got:
cpitz-virtual-0
Adapter: Virtual device
temp1: +26.8°C (crit = +127.0°C)
coretemp-isa-
Adapter: ISA adapter
Core 0: +42.0°C (high = +100.0°C, crit = +100.0°C)
Thus, no readouts for voltages or fan speeds.
After that I tried running "pwmconfig" through the terminal, to
receive:
--
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
--
My knowledge is limited and I could not find
any solutions to making the fan spin properly, that's why I decided to
ask you guys last.
I should mention that I use kernel 2.6.31-16-generic, Grub2(beta-4),
my
Acer laptop BIOS is 1.17 (the most recent one), and that inside the
BIOS
there are no options for fan speeds or voltages.
If anyone can provide any information as to what the problem is it
would
be hugely appreciated.
I paste the contents of "sensors-detect" command below. Thanks,
Thomas

(contents of "sensors-detect'):
"We can start with probing for (PCI) I2C or SMBus adapters.
Do you want to probe now? (YES/no): y
Probing for PCI bus adapters...
Use driver `i2c-i801' for device :00:1f.3: Intel ICH9
We will now try to load each adapter module in turn.
Load `i2c-i801' (say NO if built into your kernel)? (YES/no): y
Module loaded successfully.
If you have undetectable or unsupported I2C/SMBus adapters, you can
have
them scanned by manually loading the modules before running this
script.
To continue, we need module `i2c-dev' to be loaded.
Do you want to load `i2c-dev' now? (YES/no): y
Module loaded successfully.
We are now going to do the I2C/SMBus adapter probings. Some chips may
be double detected; we choose the one with the highest confidence
value in that case.
If you found that the adapter hung after probing a certain address,
you can specify that address to remain unprobed.
Next adapter: intel drm CRTDDC_A (i2c-0)
Do you want to scan it? (YES/no/selectively): y
Next adapter: intel drm LVDSDDC_C (i2c-1)
Do you want to scan it? (YES/no/selectively): y
