Hi all,
I have a computer running Ubuntu 8:10 and the noise from the fan is killing me.
When I run it in Vista the fan is more or less very quiet whatever I do.
However, once I switch to Ubuntu and run anything graphically intensive like a
short video the fan starts up and never goes away. So this has me thinking that
this may be a Graphical Processor Fan that is giving me the heart burn. A few
pointers:
Dmesg shows that ACPI is starting and locating the fans, please see attached
acpi.txt.
Although the BIOS DSDT (which supposedly can be a source of problems) is
compiled with the Microsoft compiler (MSFT), I recompiled it with the Intel
compiler without any errors so that looks fine.
a quick check on
cd /proc/acpi/thermal_zone/THZN$
$ cat trip_points
critical (S5): 105 C
$ cat state
state: ok <<even when the fan is blowing like mad.
$ cat temperature
temperature: 34 C <<still blowing like mad at this temperature yet
fan switches on at 65+
$cat polling_frequency
<polling disabled>
etc etc I cannot change any of these values though. The graphics driver is an
ATI proprietary driver that looks old?
$ dmesg |grep ATI
[ 25.826085] fglrx: module license 'Proprietary. (C) 2002 - ATI Technologies,
Starnberg, GERMANY' taints kernel.
$ fglrxinfo

OpenGL vendor string: ATI Technologies Inc.

The computer is a Toshiba satellite with an AMD Turion (64) and the graphics
card is an ATI Radeon X1250.
Thanks in advance.
