After changing the GPU from NV GPU to Intel GPU using the Nvidia X Server Settings, this application stopped working after restarting the computer. Furthermore, an error occurred when attempting to manually launch the application in the terminal.

As an aside you have to the end of the month to uplift to 20.04 due to the end of support of 18.04

What is the output of the following?

nvidia-smi --query-gpu=utilization.gpu -- format=csv

[leelewin]

Because I switched the GPU to Intel GPU, the nvidia-smi didn't work anymore.

$ nvidia-smi --query-gpu=utilization.gpu -- format=csv
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

And, I found a solution to this problem by trying to remove the nvgpu related from /home/xxxx/.indicator-sysmonitor.json file custom_text pair.
Although this solves the problem temporarily. But, I am sure there are bugs in the software.

I have the same problem.

I uninstalled my NVIDIA drivers and indicator-sysmonitor stopped working.

I suppose, the solution of problem will be removing "GPU sensors" (no drivers -> they are not supported anymore) from configuration of indicator-sysmonitor.

How can I change configuration of my indicator-sysmonitor, without starting it?

[fossfreedom]

indicator sysmonitor stores stuff in two locations - you can remove those before starting to reset things

./sensors.py:52: SETTINGS_FILE = os.getenv("HOME") + '/.indicator-sysmonitor.json'

./preferences.py:222: SETTINGS_FILE = os.getenv("HOME") + '/.cache/indicator-sysmonitor/preferences.json'

[issemLenoil]

Great, it solved my problem
