Run a Single Check
Instead of running multiple checks with one argument, you may want to run
a single check to only show the status of one diagnostic check.
To run a check to find out which Intel GPUs are on this system, use the
intel_gpu_detector_check
argument:
python3 diagnostics.py --filter intel_gpu_detector_check
You will see output similar to this:

The information in the output indicates that a GPU was present, but does not
provide any more information about the GPU or how many GPUs are present.
To get more information, use
-v
to activate verbose mode:
python3 diagnostics.py --filter intel_gpu_detector_check -v
You will see output similar to this:

Verbosity can be customized to output different levels of details. To learn
more, see Verbose Mode Options.
To see a full list of available checks, enter
python3 diagnostics.py --list
in your terminal, or see
List of Checks by Check Name.
