Temp sensors and readings on slack 10.2 need help please

Hi all,

I cannot seem to get any temp readings on my slack10.2 rig and was wondering if you all might be able to get me up and going on this.

I reallly just want to see my cpu temperature is the most important to me. I grossly overclock

I was talking to cwwilson in his DRI thread about this and it really doesn't belong there and wanted to start a new one.

motherboard: asus a7n8x-e deluxe which is an nVidia nforce 2 motherboard with an AMD processor.

from my discussion with cw:

cat: /proc/acpi/thermal_zone/THTM/temperature: No such file or directory I tried to modprobe thermal as it wasn't shown in /cat/proc/modules I looked inthe folder /proc/acpi/thermal_zone on the hard drive and there is absolutely nothing there. my kernel config for acpi is as follows: # ACPI (Advanced Configuration and Power Interface) Support # CONFIG_ACPI=y CONFIG_ACPI_SLEEP=y CONFIG_ACPI_SLEEP_PROC_FS=y # CONFIG_ACPI_SLEEP_PROC_SLEEP is not set CONFIG_ACPI_AC=m CONFIG_ACPI_BATTERY=m CONFIG_ACPI_BUTTON=m CONFIG_ACPI_VIDEO=m # CONFIG_ACPI_HOTKEY is not set CONFIG_ACPI_FAN=m CONFIG_ACPI_PROCESSOR=m CONFIG_ACPI_THERMAL=m CONFIG_ACPI_ASUS=m CONFIG_ACPI_IBM=m CONFIG_ACPI_TOSHIBA=m CONFIG_ACPI_BLACKLIST_YEAR=0 # CONFIG_ACPI_DEBUG is not set CONFIG_ACPI_EC=y CONFIG_ACPI_POWER=y CONFIG_ACPI_SYSTEM=y CONFIG_X86_PM_TIMER=y CONFIG_ACPI_CONTAINER=m I have to 'modprobe button' in /etc/rc.d/rc.modules to allow me to hit the power button and it just send the shutdown command which is nice. So I know the ACPI is working.

and then I have the following modules from his thread:

nope. same thing. my /proc/acpi only has two sub-directories. -embedded_controller -power_resource edit add: in my /lib/moduels/uname -r/kernel/drivers/acpi i have the following modules: ac.ko asus_acpi.ko battery.ko button.ko container.ko fan.ko ibm_acpi.ko processor.ko thermal.ko toshiba_acpi.ko vidoe.ko

any ideas how I can get my cpu temperature readings?

Try all the acpi stuff (processor, thermal, etc), as included, not modules

Look at my config here, see what you can do.

do you have lm-sensors installed?
also the i2c support in the kernel
with the correct hardware support?

Just out of curiosity, why do lm_sensors need to be installed?

On this laptop, I've never had lm_sensors, and I get temp, fan, etc.

What is the advantage of it?

I'm asking, because I have NEVER got it to install.

Isn't lm_sensors for 2.4 kernels? 2.6.x should have all the necessary stuff in it.

I installed Slackware on about 15 notebooks (Toshiba, Compaq, HP, Medion, Fujistu-Siemens) with different cpus (P3, P4, AMD, Centrino) and prefer the method with an initrd.gz and the default Slackware kernel out of current/testing (no need to recompile the kernel).

ACPI works great on all notebooks, even cpu frequence scaling.

With "mkinitrd -c -k kernel-version -m ac:button:battery:processor:thermal:fan:video" in /boot I create an initrd.gz (I add other modules for SATA and XFS).

A new line in /etc/lilo.conf "initrd = /boot/initrd.gz" after the "image = ..." line and a "lilo -v" make the needed changes to LiLO.

With this method it is no great action to have a full working ACPI with all features on nearly every notebook (I had installed).

I experienced on some notebooks (HP, Toshiba), that an initrd.gz with ACPI kernel modules works great, on the other side without an initrd.gz and loading the kernel modules with /etc/rc.d/rc.modules there are problems (I don't know why this happens on some notebooks).

Fluxx.

P. S.: And I never installed lm_sensors.

That sounds like just what you need, Fogie.

And kudos to you Fluxx, for showing that. (The squishy sound you hear is my head hitting the wall, saying "Why couldn't I have said that!?")

Only one problem guys -- the Asus A7N8X-E Deluxe isn't in a laptop.

I build comps, and use mostly Asus boards. I've never, I say neavuh got ACPI in any Linux kernel to work properly on a single Asus board -- though it works in Windoze on them all.

The lm_sensors app has nothing to do with ACPI. If you can get it to work, then you're head and shoulders above ACPI for output. But I don't know if there's any way to control anything with lm_sensors.

I do know that now I can see temps, fans, and voltages with lm_sensors where I never saw any of it with ACPI.

So I don't get any fan speeds, CPU temps, etc. from ACPI.

Here's a screenshot to show what GKrellM displays with lm_sensors.

For PCs, I'd recommend lm_sensors over ACPI -- actually, for anywhere you can get it to work.

I ran thru your guys advice, and I'll be honest I dont want to waste anymore of your time on this. I truly appreciate your trying to help me.

After spending about 6hrs more hours on this issue alone and so many other things in slackware that are just broken for me, I'm giving up on slackware on my main pc.

Thank you so much for your comments and help.

Old_Fogie, don't give up, try more.
I didn't have /proc/acpi/thermal_zone/THTM/temperature TOO,
and I didn't have /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

I asked about it in the thread:
http://www.linuxquestions.org/questi...d.php?t=458764
(and Fluxx gave there way to get ACPI work)

As cwwilson721 suggested, compile IN the kernel all ACPI stuff (NOT as modules!), and try with this kernel, you sould get then your /proc/acpi/thermal_zone/THTM/temperature
(I did get it after doing that)

Or follow Fluxx advise, and create initrd to load ACPI and CPU freq. scaling modules at boot time, he described how to do it.

I compiled IN the kenel CPU scaling stuff (for me -K8 modules) and again, i got my directory:/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor, and
set at boot time in my rc.local either "ondemand" or "conservative" scling governor

I believe it is worth to try to get it work for you.
good luck.

hey kubuntu puts this in their linux..

http://www.nt.phys.kyushu-u.ac.jp/sh.../download.html

and it worked on my pc, it goes straight to the chips even better than linux thru software ever could do as I recall even motherboard monitor in windows dont' do so good.

so this goes straight to the mobo...no kernel stuff

anyway a quick make package and done for slackware now

it's good to spend 10$ more and get an ASUS, they give real chips

You made a package?

hahah, yes I can make packages now can you believe it LOL

question: i just made a new kernel 2.6.17 and compile those items in with "yes" and not "module"

any command in console I can type to see if I got cpu temperature readings.

note that the xmbmon still works, as it's kernel independent, but just wondering how I might do this in console the linux software way.

Go into /proc/acpi and 'cat' around, you may find some interesting stuff....
