Notebook questions: acpid & fan working like in hell

hehejo_ · 2006-04-06 10:55:38

Hello, I'm using the stock arch kernel on my Samsung X05 Centrino notebook.

I'm not quite sure if it's a real problem - but let's see.
cpudyn is working. It scales my cpu between 1400 MHz and 600 Mhz. The governor is powersafe.

But a boot the first start of "acpid" always fails - but cpudyn is working.
Do I need acpid? The batterymonitor works.

Next thing - my fan is working and working although my cpu is nearly sleeping.

Here's some info from /proc/acpi.

[~]
cat /proc/acpi/processor/CPU0/throttling 
state count:             8
active state:            T0
states:
   *T0:                  00%
    T1:                  12%
    T2:                  25%
    T3:                  37%
    T4:                  50%
    T5:                  62%
    T6:                  75%
    T7:                  87%
[~]
cat /proc/acpi/processor/CPU0/power 
active state:            C2
max_cstate:              C8
bus master activity:     4488910f
states:
    C1:                  type[C1] promotion[C2] demotion[--] latency[000] usage[00000010]
   *C2:                  type[C2] promotion[C3] demotion[C1] latency[001] usage[00539846]
    C3:                  type[C3] promotion[--] demotion[C2] latency[085] usage[00001420]
[~]
cat /proc/acpi/power_resource/PFAN/state 
state:                   on
system level:            S0
order:                   0
reference count:         0
[~]
cat /proc/acpi/thermal_zone/THRM/*
cooling mode:   active
<polling disabled>
state:                   ok
temperature:             30 C
critical (S5):           120 C
active[0]:               65 C: devices=0xdffe9fe0

So it seemes, that one hand doesn't know that the other hand scales the cpu.
What do I have to do, that my fan is "quiet" and cools only if needed.
ATM the CPU-Temperature is about 30°C - and the fan is running like hell!

maybe he means laptop-mode-tools, it's in community, i'm trying it now..

Jap. that's exactly what I mean.

It's working great -- hm, only 2 things bother me.
At shutdown I get the error, that /etc/rc.d/laptop-mode isn't found.
And starting it manually: I get this error:

root [/home/jo]
/etc/rc.d/laptop-mode restart
:: Stopping laptop-mode                                                            [DONE] 
:: Starting laptop-mode                                                            [BUSY]
/usr/sbin/laptop_mode: line 784: echo: write error: Das Argument ist ungültig
                                                                                   [DONE] 
root [/home/jo]

Das Argument ist ungültig == the argument is not valid.

779 # Set kernel setting, showing an error if this fails.
780 # Parameter 1: sysctl/proc path
781 # Parameter 2: the value
782 set_sysctl() {
783     echo "Executing: echo $2 > $1" >> $OUTPUT
784    if ! echo "$2" > "$1" ; then
785        echo "SETTING OF KERNEL PARAMETER FAILED: echo $2 > $1"
786    fi
787 }

Hacking into that file and >ing it to a file it get's me this:
Executing: echo 1 > /proc/sys/vm/dirty_background_ratio

But I don't know what's wrong.
