So, if you need a CPU temp monitor that can do more than just monitor CPU temperatures, HWMonitor is worth a look.
All other sensors are performing normally in System Monitor. HWMonitor displays not only your CPU’s temperature, core voltage, operating frequency, and load, but it is also able to monitor your GPU, your fan speeds, your storage devices, and plenty more. I am happy to help in any way I can as I really miss the ability to quickly reference the GPU state (I have a small display dedicated to telemetry output). I tried taking a screenshot of the dropdown list issue, but it seems to disable the printscreen function when its visible. temperature-monitoring gnome-shell-extension cpu-temperature disk-temperature gpu-temperature. I am somewhat less concerned about the GPU usage or temps, and more about the memory usage, leaks, and scheduling (such as ensuring all CUDA enabled devices are performing - IE both GPUs and the CPU in Blender or Resolve). Shows CPU temperature, disk temperature, video card temperature (NVIDIA/Catalyst/Bumblebee&NVIDIA), voltage and fan RPM. I have run ksystemstats and it says it is loading all the plugins, I have run lm-sensors and added some missing modules, but neither of these things had any effect. Psensor shows both GPU’s, correct temps and usage, but it appears the memory usage is being reported incorrectly, and it does not show frequency.
Running nvidia-smi shows the correct values. It seems something broke the GPU part of it in 5.27.7, as they were all working fine right up until the last update.
I tried adding the GPU page and its showing the same errors. It seems to be an issue with Sysmon and applets.
