Auxilary GTX 1050ti no longer detected by system...

So I had a RTX 2080 and a GTX 1050ti running in unison…

I had sli turned on and

nvidia-xconfig --multigpu=afr

[don’t know which is better, sli or multi gpu in my case]
The gtx 1050ti is no longer dtectable by nvidia or gnome.

Linux knows its there…

05:00.3 Serial bus controller [0c80]: NVIDIA Corporation Device 1ad9 (rev a1)

Fedora 29 415.27 will boot up, but know gtx 1050 ti.
Debian sid 418.30 says something about an unrecognizable chip and tries to load nouveau and fails to start x.

Debian boots just fine if the gtx 1050 ti is out of the slot.

I am at a loss for as to what to do.

based on this info…

Why is the gtx 1050ti loading with nouveau and not nvidia like it is supposed to be doing?

SLI/Multigpu only works with the same gpus.
Nouveau should be blacklisted.
