You can specify which GPU to use with the program nvidia-settings.
Using: the GPU "PRIME Profiles" set for "Intel (Power Saving Mode)" which sets:
$cat /proc/acpi/bbswitch
0000:01:00.0 OFF
After a few days of this setting I can report that the issue of the
dimming screen and random lock-ups seems to have disappeared.
----
I've just now run nvidia-settings to change back to use the GPU that's
labeled "NVIDIA (Performance Mode)" and will update in later if this
also no-longer has the issue.
Tentatively reporting as fixed pending further testing .
