is my power supply dieing?

[Michael Butash]

Try "sudo lshw -c display"

It might be an integrated gpu inside the cpu, intel loves to sell you
drivel whether you want it or not (they learned from microsoft).  If it is
nvidia, it should be a physical card.

Looks there at least on an ubuntu 20.04 server of mine at the moment.
