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 - sensors-detect has been run and the kernel module - correctly installed. sensors 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 nvidia-settings to - check that it supports sensors monitoring. -

      -
      • -
    • -

      -proprietary driver Catalyst/fglx: use aticonfig to - check that it supports sensors monitoring. Important - note: it requires that you are using a Psensor - binary compiled with the ATI support. -

      -
      • -
    -
    • -
-

For hard disk drives, psensor can use:

-
    -
  • -

    -udisks2: added since 1.1.2 release. It is the default and - recommended provider. -

    -
    • -
  • -

    -hddtemp: verify that it is correctly reporting temperature by - using the command: sudo hddtemp /dev/sda. It is the default - provider until 1.1.2 release. -

    -
    • -
  • -

    -atasmart library: before the 1.1.2 release it can be enabled - by using the command line option --use-libatasmart. -

    -
    • -
-

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.

-

Since the release 1.1.2, the providers can be enabled or disabled directly -from the user interface (Preferences>Provider).

-
-
-
-

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 ATI/AMD GPU Support 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: sensors, aticonfig or - hddtemp 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:

-
    -
  • -

    -lmsensor coretemp: Intel CPU. -

    -
    • -
  • -

    -lmsensor k10temp, lmsensor k8temp, lmsensor fam15h_power: AMD CPU. -

    -
    • -
  • -

    -nvidia or lmsensor nouveau: NVIDIA GPU. -

    -
    • -
  • -

    -hdd: hard disk drive. -

    -
    • -
  • -

    -amd: AMD GPU. -

    -
    • -
  • -

    -lmsensor C B: C is the name of the chip, B the name of the adapter. -

    -
    • -
-

For more information about lmsensor devices, see -http://lm-sensors.org/wiki/Devices.

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 don’t want to use the launchpad, you can send the report by -email to:

-
-

If the bug is concerning Debian or Ubuntu derivatives distribution, -please add in its description the output of the command: apt-cache -policy psensor.

-

If it is related to the Psensor source compilation, please add the -full output of the configure command.

-
-
-
-

6. How to send ideas, questions or comments?

-
-

Check the FAQ or the TODO pages.

-

If you don’t find the information, you can send an email to the public -mailing-list psensor-users@googlegroups.com or directly to me: -jeanfi@gmail.com.

11. How to install Psensor on ArchLinux?

-
-

See http://aur.archlinux.org/packages.php?ID=37807.

-
-
-
-

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 Installation from source -archive 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 -(--sensor-log-file option). For psensor the log file is -$HOME/.psensor/sensors.log.

-
-
-
-

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. Launch Psensor automaticaly on session startup

-
-

Since the version 1.0.1, Psensor is no more started automaticaly by default.

-

Open the Preferences window, select the Startup tab and switch on -the option Launch on session startup.

-

This feature is requiring that the Desktop Environment supports the -XDG -specification.

-
-
-
-

16. How to monitor the temperature of a disk with hddtemp?

-
-

Until the release 1.1.2, Psensor is using hddtemp by default to -retrieve the temperature of the disks.

-

If hddtemp is installed but no disk temperature is reported, check -that the daemon is running by using for example the command ps --eaf|grep hddtemp. -It should output something like:

-
-
-
root      1433     1  0 May28 ?        00:00:21 /usr/sbin/hddtemp -d -l 127.0.0.1 -p 7634 -s | /dev/sdb
-
-

Depending on the Linux distribution, the installation of the hddtemp -package does not enable the hddtemp daemon automaticaly.

-

In this case, edit the file /etc/default/hddtemp and set -RUN_DAEMON to "true". After edition, it should contain the -following line:

-
-
-
RUN_DAEMON="true"
-
-

For Debian/Ubuntu, you can use at root:

-
-
-
dpkg-reconfigure hddtemp
-
-

and reply yes when asked whether hddtemp daemon must be -run during the startup.

-
-
-
-

17. Is there any other similar softwares?

-
-

Here is a list of few well-known sensors monitoring softwares:

-
-
-
-
-

18. Is it possible to hide sensors in the main window?

-
-

Before v1.1.1, the sensors retrieved from the lm-sensor library can be -ignored directly in the lm-sensor configuration. See the manpage -of sensors.conf(5).

-

Since v1.1.1, it is possible to hide a sensor, uncheck the setting -Display sensor in the list of sensors in the sensor preferences.
