W520, Linux and CPU temps

[dimm0k]

Any Linux users here? Just wondering if anyone has been able to get some thermal readings from this notebook under Linux... it works fine under Windows 7, but under Linux it has been another story. Currently running kernel 2.6.39.2.

Tell you what, if it's anything like my T410, then you will have some problems ....
See this thread - http://forum.thinkpads.com/viewtopic.php?f=9&t=97277

...and yes we have some VERY knowledgeable Linux users here.

Interesting... read through your link, but I don't really see any trouble as you do have access to some sort of reading regarding CPU temps. According to ThinkWiki /sys/devices/platform/thinkpad_hwmon should list some entries that pertain to temp, but on my system there are none. Not sure how similar my W510, which I no longer have, is compared to your T410, but I'm curious if your system has any entries under /sys/devices/platform/thinkpad_hwmon that stand out as temp readings.

I can confirm that it works fine on my W520 with Ubuntu 11.04 and kernel 2.6.38-8-generic, see details here http://forum.notebookreview.com/lenovo- ... ost7646736.

In the image that you posted at NBR, it shows (6) temperatures. What are they?

Hrmm, that does not seem to exist on the W520 notebook!

I installed sensors-applet under a Ubuntu 11.04 64-bit Live CD, but am not able to get the same display as you. At most I can get the HDD temp and only one other temp, which looks like it might be the CPU? What temps are you able to pull off because in your screenshot there's a total of 6 readings!

Also wonder what BIOS version you have and if the one I'm using, 1.22, is missing some readings that would give me what you see on yours.

Hi dimm0k, pitty there is no possibility to attach the screenshot in this forum, therefore: right click on the applet in the pannel -> preferences, select tab Sensors and then you will be able to define what is displayed:
>nvidia
GPU0CoreTemp
>udisks
/dev/sda
>libsensors
temp1 (that is motheboard temperatur sensor)
Core 0
Core 1and so far....
fan1
>ibm-acpi
FAN
>hdtemp
/dev/sda.
I am still running 1.06 BIOS and happy...

Hrmm... I was able to go into the preferences to change some of the views, but under libsensors there was only one reading available. Don't remember it offhand, but it was not temp1 or anything Core related. I might have to go to 1.06 to see if that gives me back some readings before starting a thread on the Lenovo forums to get some action. I know for sure that 1.24/25 breaks anything ACPI related under Linux.
