Operating without the NVLink connector, everything starts normally.
Please let me know if any additional data is required. I am using the NVidia drivers from RPMFusion. I have tested this configuration under Windows 10, and it operates as expected with the Nvidia drivers.
Short notice, please wrap your code into high ticks to make them better readable:
```
Code
```
Regarding your issue: the errors do not look like nvlink is failing, but more that there is already X running. Can you please post your output of dmesg? I am looking for lines like this (taken from here):
[ 1105.780063] ipmi device interface
[ 1105.974672] nvidia: loading out-of-tree module taints kernel.

Also, just to be sure about this: you did not install any prime/bumblebee things, am I right? And did you configure your xorg.conf properly? Was it maybe changed by some mechanism?
This is a fresh install of Fedora 31 - I did not make any configuration changes to the xorg.conf - i simply installed the NVidia drivers via RPMFusion, following their directions.

Ok, then I am out of ideas. Maybe you have more luck at a move nvidia-Linux specialized forum? Phoronix maybe, or some reddit community?
And if you ever solve it I would be happy if you could let us know what the issue was…
