+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
note: it requires that you are using a Psensor
binary compiled with the ATI support.
- - HDDs: it uses the hddtemp daemon. Verify that it is
- correctly reporting temperature by using the command: +sudo
- hddtemp /dev/sda+. If hddtemp does not support your disk,
- you may want to try using the libatasmart support instead
- (option +--use-libatasmart+).
+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
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+).

Anyway, as I received several requests about such feature, since the
0.7.0.4 release it is implemented in both psensor ( menu preferences >

+How to monitor the temperature of a disk with +hddtemp+?
+--------------------------------------------------------
-By default, Psensor is using +hddtemp+ to retrieve the temperature of
-the disks.
+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
package does not enable the hddtemp daemon automaticaly.
In this case, edit the file +/etc/default/hddtemp+ and set
-+RUN_DAEMON+ to +"true"+ like in the following example:
++RUN_DAEMON+ to +"true"+. After edition, it should contain the
+following line:
------------------
-# hddtemp network daemon switch. If set to true, hddtemp will listen
-# for incoming connections.
RUN_DAEMON="true"
