I suppose, it is the "Option="-q" in the /etc/init.d/powernowd-Script, isn`t it ?? Or is there another way, to change the behavior ? I read in the documentation, that a file can be written in /etc/default/ called "powernowd", but I do not know, what content must be in it. Do you have an example ? I suppose, to edit the script in /etc/init.d/ should work to.

The default is to go straight to full speed whenever there is cpu load >80% and then slowly drop down as long as the cpu is <20%. I didn't find that very usefull for me. Instead I switched to SINE mode so it slowly changes without sudden jumps. I also changed the limits to 50% and 95% so it is more biased towads slow. For a laptop the PASSIVE mode is probably best where it jumps to the slowest speed whenever cpu goes <20% and only slowly rises with cpu >80%. It will feel more sluggish to react though. Or the LEAPS mode, what you described. MfG Goswin -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
Re: The fan of the laptop never stops with amd64
Hi everyone, I finally succeded with the fan issue. powernowd did the magic (I didn't have it installed). Also helped acpid and disabling the suid bit in klaptop_acpi_helper.

I find it works well enough for my needs, so I don't even use a userspace tool such as powernowd to control it. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

Re: The fan of the laptop never stops with amd64
Hello, what kernel are you using? try linux-image-2.6.12-1-amd64-k8 from unstable (nvidia/ati modules need gcc-4.0 to compile then), or thze 2.6.12.5 + acpi patch from http://213.178.77.236/laptop/ at least on my turion based laptop the fan control works pretty well.

Re: The fan of the laptop never stops with amd64
Are you using powernowd? powernowd allows dynamic cpu frequency and core voltage scaling. For instance, my 1800MHz (1.5V) runs at 1001MHz (1.1V) most of the time. Of course, the side effect is lower power (heat) dissipation so the fan(s) can slow down. -Pascal On 8/29/05, A, Manchado <[EMAIL PROTECTED]> wrote: > I recently bought a Turion laptop with Knoppix-32bit preinstalled. > The fan used to run and stop now and then. > Now I have installed debian-amd64-testing and when the fan starts > working (15sec to 30 sec after booting) then it never stops again. > Furthermore, the battery lasts 30% less time approx. than with 32bit. > I am wondering why, and got 2 hypothesis: > 1) Turion is dissipating a lot more power when running in 64bit mode. > 2) There is something wrong with the control of the fan in debian-amd64. > However, all acpi modules (thermal.ko, fan.ko, etc.) are loaded at boot > time (I had to add them to /etc/modules) and they seem to be working > 'cause I got battery level indication in the kde panel. > Has anyone experienced this behaviour?

The fan of the laptop never stops with amd64
I recently bought a Turion laptop with Knoppix-32bit preinstalled. The fan used to run and stop now and then. Now I have installed debian-amd64-testing and when the fan starts working (15sec to 30 sec after booting) then it never stops again. Furthermore, the battery lasts 30% less time approx. than with 32bit. I am wondering why, and got 2 hypothesis: 1) Turion is dissipating a lot more power when running in 64bit mode. 2) There is something wrong with the control of the fan in debian-amd64. However, all acpi modules (thermal.ko, fan.ko, etc.) are loaded at boot time (I had to add them to /etc/modules) and they seem to be working 'cause I got battery level indication in the kde panel. Has anyone experienced this behaviour? Is it normal? Regards, amm -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
