ack. Is yours the "ubuntu" session? i.e. auto-detection, the default, not "ubuntu-xorg" which is manually selecting "Ubuntu on Xorg" from gdm. Check $DESKTOP_SESSION. I can confirm that if I pick ubuntu-xorg then nvidia-smi looks like yours.
I see from `lsmod` that nvidia is loaded - apparently that's not enough to get it to be used though. I would have expected the udev rule (61-gdm.rules) to have fired here and caused gdm-disable-wayland to run, so that I got Xorg and things running on the nvidia GPU; is that a valid expectation?

The first boot is always xorg, and nvidia mode is selected. After that reboots are *usually* wayland, but sometimes they are xorg too. Performance mode is selected in nvidia-settings, which is supposed to mean nvidia & therefore xorg but it's not working. Selecting it explicitly doesn't help either. What is the default meant to be - probably ondemand? Seems like it's somehow nondeterministic. Attaching some logs.
