3060 not showing up on boot

ASUS 570-ACE motherboard, latest bios updates.
Have installed ubuntu 20.04 from scratch, added cuda. Reboots, can see post screen / loading text, gets to login screen and stops displaying anything.

Can see the device with lspci:

0b:00.0 VGA compatible controller: NVIDIA Corporation Device 2504 (rev a1)
0b:00.1 Audio device: NVIDIA Corporation Device 228e (rev a1)

According to the internet this is one of the new hashrate limited cards fwiw. I am trying to do machine learning.

Nvidia log has make errors for the kernel for what it’s worth:
nvidia-bug-report.log.gz (274.8 KB)

Swapped Power cables, was using this same slot for a different card previously. Put into a different machine am seeing the same under 18.04.

20.04 lts server fwiw. could login and things were working initial boot with a displayport cable but after installing cuda get the above results.
