Additional Information (if applicable)

  • Bashtop and Bpytop(snap version)
  • Bpytop is freshly installed and updated ---- Bashtop is updated

Steps to reproduce

  1. Bashtop has never displayed temperatures readings(‘Sensors’ is installed)
  2. I thought Bpytop may display them, but it fails as well.

Expected behaviour

  • There should be a Temperature output box beside the Core Usage display box

Actual behaviour

  • Temperature output is missing on both Bashtop and Bpytop

Extra details

  • Iinxi and sensors output are very close iin their temperature readings


That’s so far over my head I couldn’t see it even with Hubble.


You say sensors is installed, but what output do you actually get when you run it?

I have two desktop systems:

  1. A ~10 year old HP business tower model with a Core i5 CPU and a totally unsupported hardware monitoring chip/platform — the only sensors data I get is per-core CPU temps from coretemp:

    $ sensors
    Adapter: ISA adapter
    Package id 0:  +37.0°C  (high = +80.0°C, crit = +99.0°C)
    Core 0:        +33.0°C  (high = +80.0°C, crit = +99.0°C)
    Core 1:        +32.0°C  (high = +80.0°C, crit = +99.0°C)
    Core 2:        +32.0°C  (high = +80.0°C, crit = +99.0°C)
    Core 3:        +37.0°C  (high = +80.0°C, crit = +99.0°C)
  2. An even older Acer Aspire box based on an AMD Athlon 64 X2 CPU, which also has a well-supported it8716 sensor chip from which I get a wealth of readouts:

    $ sensors
    Adapter: PCI adapter
    Core0 Temp:   +30.0°C  
    Core0 Temp:   +21.0°C  
    Core1 Temp:   +38.0°C  
    Core1 Temp:   +25.0°C  
    Adapter: ACPI interface
    temp1:        +16.0°C  (crit = +70.0°C)
    Adapter: ISA adapter
    VCPU:          1.10 V  (min =  +0.61 V, max =  +1.79 V)
    in1:           2.50 V  (min =  +0.00 V, max =  +4.08 V)
    VMem:          1.79 V  (min =  +0.00 V, max =  +4.08 V)
    +3.3V:         3.33 V  (min =  +0.00 V, max =  +4.08 V)
    in4:           2.94 V  (min =  +0.00 V, max =  +4.08 V)
    in5:           1.17 V  (min =  +0.00 V, max =  +4.08 V)
    in6:           2.88 V  (min =  +0.00 V, max =  +4.08 V)
    in7:           3.07 V  (min =  +2.40 V, max =  +3.60 V)
    Vbat:          2.86 V  
    CPU Fan:     1864 RPM  (min = 1500 RPM)
    System Fan:  1250 RPM  (min =  399 RPM)
    CPU Temp:     +16.0°C  (low  =  +0.0°C, high = +70.0°C)  sensor = thermal diode
    M/B Temp:     +38.0°C  (low  =  +0.0°C, high = +60.0°C)  sensor = thermistor

…Despite this, system #1 shows the temp next to each core when running bashtop, whereas system #2 shows no temps. In fact, if I go into the Bashtop Options screen (Esc, Options) on both systems, system #1 has “Check temp” defaulted to “true”, whereas System #2 forces it to “false” and will not let me enable it.

I conclude from this that Bashtop, at least, only supports reading temperature data from the kernel’s CPU hardware monitoring driver, and doesn’t support the k8temp driver used for AMD CPUs. Likely Bpytop is the same.

And to put an even finer point on it: Because Bashtop is able to detect that it can’t get temps on system #2, and even lock the “Check temp” setting to “false”, I’m guessing this is a known limitation of the software. Most likely everything is working as expected. (After all, someone clearly wrote code in Bashtop to account for this situation and override the Options menu item.)

Here is the readout from Sensors:

$ sensors
Adapter: PCI adapter
power1: 69.63 W (crit = 95.06 W)

Adapter: PCI adapter
temp1: +50.0°C (crit = +120.0°C, hyst = +90.0°C)

Adapter: PCI adapter
temp1: +4.9°C (high = +70.0°C)
(crit = +70.0°C, hyst = +67.0°C)

I got Bpytop to give a small temperature display of k10temp on the same line as the CPU usage. I had to take it off of the Auto setting and move it to the k10temp setting.

I see from your output comparisons that the problem is just a lower functioning hardware.

Thank you for your help.
