sensors-applet randomly picks up duplicates

[Delan Azabani]

Binary package hint: sensors-applet

Almost every time I boot my computer, sensors-applet adds a couple of duplicate sensors for my CPU cores, usually not all of them. Running the sensors command does not have any duplicates. I have to open the preferences and untick them to hide them, but they can't be removed.

[Alex Murray (alexmurray)]

Can you please post the output of the sensors command when sensors-applet shows duplicate sensors and when it doesn't show duplicates?

Also could you post the output when running sensors-applet from the command line.
Open a terminal and type:

killall sensors-applet

and hit Return. Then a window should appear saying:

"Hardware Sensors Monitor" has quit unexpectedly.
If you reload a panel object, it will automatically be added back to the panel.

DON'T CLICK ANYTHING YET. Go back to the terminal window and type:

/usr/lib/gnome-panel/sensors-applet

and hit Return. Then go back to the pop-up window and choose 'Reload' at which point a heap of output should appear in the terminal window from sensors-applet - please copy this and attach it to this bug report.

Thanks for your help. I'll have to wait for this to occur again. It's currently not happening, though it almost certainly will in the near future.

I've noticed the same thing happens to me when I reboot.

From the debug output it looks like there are already duplicate entries for some sensors saved in sensors-applet's settings - basically what is happening is that libsensors is not providing consistent naming of sensors across reboots - so on first boot sensors-applet gets the list of sensors from libsensors with names A,B,C say, and then saves this list of sensors in its settings along with whether they are enabled etc, graph colour and whotnot. Then on next boot, for the same set of sensors, libsensors returns names D,E,F and so these look like different sensors (they have different names) and so sensors-applet may also save this new list of sensors to its settings - so now in the sensors-applet settings we have sensors A,B,C,D,E,F even though at any one time there is really only either A,B,C or D,E,F - so this is really a bug in libsensors for not providing consistent naming, not sensors-applet since there is no way to know that D is really A since it actually looks like a new sensor.

With what little knowledge of Linux that I have I'd say you are correct because when the new sensors appear they do so with default colors as opposed to the customized ones which are checked off in the box to run.

So does that mean it must be reported as a libsensors bug?

[Chuck Short (zulcss)]

Which version is this with anyways?

[LoneWolf_53 (spezi-machek)]

I've upgraded to Natty since posting here so not sure if the version changed with Natty or not.

What I'm showing is sensors-applet 2.2.7-2ubuntu2 if that's what you are asking.

[Alex Murray (alexmurray)]

I think he meant the lm-sensors version not sensors-applet.
