Dell XPS 15 nvidia card not seen by Ubuntu after reboot and not seen even after fresh Ubuntu reinstall

I was playing a game on Steam and it stopped working after random reboot (possibly after an update). I remember previously having to enable manually the nvidia drivers, so I went to Software & Updates and to the Additional Drivers tab, but nothing is showing up there, it just says No additional drivers available. So, the system does not appear to recognize at all that there is an nvidia card inside and only the integrated graphics shows up.

sudo lshw -C video

I’m worried that this is a hardware problem, because I would assume that a fresh system reinstall should have fixed this… I’m attaching nvidia-bug-report. Could someone help me identify the problem please?

The gpu is gone, likely died. You could try resetting the mainboard
If that doesn’t help, you can only send it in for repair.
