1. No sensors or only cpu usage is displayed
-Psensor is relying on few libraries or softwares for retrieving the information about the computer:
-
-
-
-
-motherboard and CPUs sensors: the information is retrieved - from the lm-sensors library, it requires that - âsensors-detectâ has been run and the kernel module - correctly installed. âsensorsâ can be used for checking. -
-
- -
-
-GPUs: it depends on which driver you are using: -
---
-
-
-
-Opensource drivers (nouveau for Nvidia GPUs or - radeon/ati for ATI GPUs) is used and support sensor - monitoring for your GPU, the information is using - lm-sensors, same steps than above. -
-
- -
-
-proprietary driver Nvidia: run ânvidia-settingsâ to - check that it supports sensors monitoring. -
-
- -
-
-proprietary driver Catalyst/fglx: use âaticonfigâ to - check that it supports sensors monitoring. Important - note: it requires that you are using a Psensor - binary compiled with the ATI support. -
-
-
- -
-
-
-
-HDDs: it uses the hddtemp daemon. Verifies that it is - correctly reporting temperature by using the âsudo hddtemp - /dev/sd?â command. If hddtemp does not support your disk, - you may want to try using the libatasmart support instead - (option âuse-libatasmart option). -
-
-
If the underlying software is reporting sensors which are not -displayed by Psensor, it is probably a bug in Psensor, so please -report it. Otherwise, the issue is on the underlying software itself -and you should contact the corresponding development team or refer to -its documentation.
2. How to monitor an ATI card using the Catalyst driver?
-For monitoring ATI card using the proprietary Catalyst driver, Psensor -must be compiled with a proprietary library which is not packaged in -any Linux distribution.
Unfortunely, due to the license of this library, I cannot provide a -compiled version of Psensor, even in a Ubuntu PPA or Ubuntu/Debian -standard repositories. You have to compile Psensor sensor. You can -find the instructions in the section âATI/AMD GPU Supportâ of the -README file available in the Psensor source archives.
If you are using the ATI OpenSource driver, it is not needed to -compile Psensor with this proprietary library.
3. The reported temperature is obviously wrong
-If the reported temperature is obviously wrong (never change, lower -than the ambiant temperature, negative, higher than the sun -temperature, etc):
-
-
-
-
-most of the time it is not a bug in Psensor nor in the - underlying monitoring libraries: -
---
-
-
-
-if the temperature does not change, it might be due - to an existent sensor not wired by the hardware - manufacturer. -
-
- -
-
-the goal of the sensor is to allow the system to - detect critical temperature and NOT to report an - exact temperature. Most sensors report a relative - temperature. The more it differs from the critical - temperature , the more it is wrong. -
-
-
- -
-
-
-
-It is only a bug in Psensor if the underlying libraries - report a different information than Psensor (use the - appropriate command or software: âsensorsâ, âaticonfigâ or - âhddtempâ to check). In this case, please report a bug. -
-
-
4. What is the sensors XXXX?
-Since Psensor v0.7.0.4, open the preferences of the sensor (click on -its name in the main window and select the menu item Preferences), and -look at the Chip field.
For older Psensor releases, look at the Id field, if the string is -starting with:
-
-
-
-
-âlmsensor coretempâ: Intel CPU. -
-
- -
-
-âlmsensor k10tempâ,'lmsensor k8tempâ,'lmsensor fam15h_powerâ: AMD CPU. -
-
- -
-
-ânvidiaâ or âlmsensor nouveauâ: NVIDIA GPU. -
-
- -
-
-âhddâ: hard disk drive. -
-
- -
-
-âamdâ: AMD GPU. -
-
- -
-
-âlmsensor C Bâ: C is the name of the chip, B the name of the adapter. -
-
-

5. How to report a bug?
-Please use https://bugs.launchpad.net/psensor/+filebug to report bugs -even if it can only reproduced with a non-Ubuntu distribution or a -release not available in the standard Ubuntu repositories.
You can also use -https://bugs.launchpad.net/ubuntu/+source/psensor/+filebug if the bug -can be reproduced with a package from the standard Ubuntu -repositories.
If you donât want to use the launchpad, you can send me the report by -email to jeanfi@gmail.com.
If the bug is concerning Debian or Ubuntu derivatives distribution, -please add in its description the output of the command âapt-cache -policy psensorâ.
If it is related to the Psensor source compilation, please add the -full output of the âconfigureâ command.
6. How to send ideas, questions or comments?
-Check the FAQ or the TODO pages.
If you donât find the information, I am always happy to help, you can -contact me:
-
-
-
-
-by email: (jeanfi@gmail.com), please add â[psensor]â in the - subject, I speak English and French. -
-
- -
-
-or IRC: I am on the #psensor channel of the irc.freenode.net - server. My nickname is âjfiâ. Even if I am most of the time - connected, I may not be in front of the computer or - available, be patient! -

7. How to contribute?
- -8. How to install Psensor on Ubuntu?
-Psensor is in the official repository, search âpsensorâ in the software center and install it. More information at: http://wpitchoune.net/blog/psensor/ubuntu-integration/.
9. How to install Psensor on Debian?
-Psensor will be in the official repository since Debian 7.0. You can get the last packaged version from the sid repository. More information at: http://packages.qa.debian.org/p/psensor.html.
10. What is the difference between the 3 Ubuntu PPAs?
--
-
-
-
-ppa:jfi/ppa: last stable version. -
-
- -
-
-ppa:jfi/psensor-unstable: last development version, no major - bug is expected. -
-
- -
-
-ppa:jfi/psensor-daily-trunk: build each day directly from - the SVN source repository. It may contain major bugs or - incomplete features. Useful for contributors or testing - whether a bug is fixed. -
-
-
11. How to install Psensor on ArchLinux?
- -12. How to install Psensor on my Linux distribution?
-Psensor packages are available in the standard repositories of Ubuntu -(since Oneiric) and Debian (since v7) distributions.
For other distributions, you will find the compilation and -installation instructions in the section âInstallation from source -archiveâ in the README file of the source archive. Psensor should -compile in any modern distribution.
13. How to log sensors temperatures?
-The best way is probably to use sensord or a custom script based on -the output of the different commands like sensors.
Anyway, as I received several requests about such feature, since the -0.7.0.4 release it is implemented in both psensor ( menu preferences > -sensors > enable log of measures) and psensor-server (âsensor-log-file -option).
14. No graphs are displayed, but the table of the main window is displaying sensors
-In the sensors table of the main window, switch on the checkbox of the last -column (named "Enabled" or "Graph" depending on the Psensor version).
15. Is there any other similar softwares?
-Here is a list of few well-known sensors monitoring softwares:
-
-
-
-
-for X11: http://freecode.com/projects/xsensors -
-
- -
-
-for GNOME2: http://sensors-applet.sourceforge.net/ -
-
- -
-
-for Ubuntu Unity: https://launchpad.net/indicator-sensors -
-
- -
