sensors command only shows the CPU temp

Postby Drowen on Tue Mar 19, 2013 5:21 am

Hello,

After the difficulties with Ubuntu, I installed Linux Mint 14 Cinnamone yesterday without any problem.

I installed lm-sensors in terminal and used sensors-detect command. My sensors output for the GPU temp was 63C so I also installed Ati Catalyst 13.1 driver for my HD6850. After the reboot, sensors command only gave me the CPU core temps.

Code: Select all
coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +26.0°C  (high = +74.0°C, crit = +100.0°C)
Core 1:       +22.0°C  (high = +74.0°C, crit = +100.0°C)
Core 2:       +38.0°C  (high = +74.0°C, crit = +100.0°C)
Core 3:       +39.0°C  (high = +74.0°C, crit = +100.0°C)


I uninstalled the sensor packages from synaptics package manager then reinstalled the packages in terminal. After the reboot the results are the same.

Probably my GPU temp is low now after I Installed the Ati driver but I want to see the result.

Could you help me?

Many thanks.

Linux Mint is funded by ads and donations.

I think sensors command will not show GPU after fglrx installation.

Could you tried this in the terminal to see if it works?

On root terminal
Code: Select all
# aticonfig --odgt



example, mine is
# aticonfig --odgt

Default Adapter - ATI Radeon HD 5450
Sensor 0: Temperature - 55.50 C


and sensors shows two CPU core temp
# sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +39.0°C (high = +89.0°C, crit = +105.0°C)
Core 2: +39.0°C (high = +89.0°C, crit = +105.0°C)


if I use free radeon driver, the GPU temp would easily reach 65-68degC when idling.

sensors (lm-sensors) does not show GPU temperatures of AMD and NVIDIA proprietary drivers because those drivers have their own interfaces for temperature monitoring. inxi -s can show GPU temperature, though.

@wayne128 and @AlbertP thank you for your answers. I ran "aticonfig --odgt", the output is :

Code: Select all
Default Adapter - AMD Radeon HD 6800 Series 
                  Sensor 0: Temperature - 42.00 C


a few seconds later I ran again :

Code: Select all
Default Adapter - AMD Radeon HD 6800 Series 
                  Sensor 0: Temperature - 37.00 C


What is the reason of the increasing the temp? I use Chromium by the way.

Hmm, I think I found it...The animations of the openning and closing the menus cause it, It's not that much at least.

@wayne128 your gpu temp is really high and CPU is also.

@ Drowen: Wayne has quite normal temperatures. His GPU is a Radeon 5450 so probably passively cooled: those usually get a bit hotter. 55°C is not a problem. And 39°C CPU temperature is also nothing special.
My passively cooled GeForce 6200 is 52°C now (after letting the computer on for a while). In fact many older passively cooled cards are much hotter.

@ AlbertP, thanks for your explanation.



@ Drowen,
I think the main reason why my cpu/gpu temps higher is:
My room temp is 30-31 degC :mrgreen: living in equator, whole year 23-35degC!!
I kept them cool by chosing certain distros /kernel and run open casing.
