Fan speed support in Helena removed?

Postby hoppel on Tue Dec 01, 2009 8:04 am

Hi,


when I tried to recover the fan speed settings that I made in Gloria using this tutorial(http://wiki.ubuntuusers.de/L%C3%BCftersteuerung), I used the mentioned script "sudo pwmconfig". But instead of getting a list of detected sensors I got the error message "/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed". Is there anything I forgot to install? Or is there hardware support missing in Helena, which was present in Gloria?

Hardware: ASUS M3N78 pro mainboard with AMD X25050e CPU.

Not sure if this will help . . . but have you installed, and run lm-sensors?

It's true, I forgot to enter "sensor-detect" - but after that I'm stuck again: sudo pwmconfig gives me the following error:
Code: Select all
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

Is there anything elso I might have forgot? This is really hard to configure, I wish there would be a tool for it...

Did you forget to reboot? . . . :)

Sorry, I cannot reproduce the error, it has worked on every laptop that I have installed it on . . . don't know where to go from here . . anyone else?

No, I rebooted... I have no laptop, but since all this stuff worked in Gloria, I'm a bit confused. i probably made some unseen mistakes...

One last thing that comes to mind, is the Power Management/ Fan Speed settings in your BIOS . . . have you checked the settings there? Make sure they are turned on. Have you updated or reset the BIOS recently?

No, it's the same as before. It set to manual, so that those tools can take effect. I installed Helena just a few days ago, until then it worked with Gloria, and it still does with Windows and Speedfan. Just to be sure: Which commands do I have to enter?

This is pretty weird. But all tutorials I have found are verified only for older versions of Ubuntu or Mint. Until now there seems to be nothing verified for Karmic/Helena. Does anyone have a newer manual?

I found something that might be an explanation:

Yes, doing some reading in that thread and links, I see that the the new kernel does strict resource enforcement that it didn't do before. ASUS motherboards seem to commonly have some resource conflicts.

These can be fixed by using new drivers such as asus_atk0110 but this requires lm-sensors 3.1 which isn't in karmic yet. You can build it yourself or use someone else's build of lm-sensors (see https://bugs.launchpad.net/ubuntu/+s...-3/+bug/336418)

It's not the "proper" fix but in the interim you can add "acpi_enforce_resources=lax" to the boot command line and this will revert the ACPI behavior back to the old (wrong) way.

Remember: I have an ASUS mainbord. But although this explanation might help, I'm not expert enough to understand it completely. Would those changes help me? And if so, how do I apply them to my system?

Meanwhile I installed a new version of lm-sensors, like mentioned in thread I've posted. Now I get sensor readings again (hurray!), but pwmconfig still refuses to work. This is strange...
