The 2080 Ti graphics card has an USB-C output, that works if I connect 
an USB storage device
(see the DataTraveler device below).

Should I try the USB port as a video output ? I need to bring in an 
USB-C monitor first
from a different location. I also have an USB-C to HDMI adapter, but 
using such an
adapter gives a different crash with nouveau driver, that I found on a 
different machine
(my work laptop at the time), that I reported before. So I suppose it 
would not be a
good test now.
