Fedora 29 no displayport output.

That is something I can try after I get off work.

was looking around and found the following:

$cat /usr/share/abrt/conf.d/plugins/xorg.conf
# List of modules which, when loaded, should make
# Xorg crashes non-reportable.
# Names should be without "_drv.so" suffix:
BlacklistedXorgModules = nvidia, fglrx, vboxvideo

# List of filters which is used for searching Xorg crashes in journal
JournalFilters = _COMM=gdm-x-session, _COMM=gnome-shell

should nvidia be in the blacklist?

I wouldn't expect that to affect anything other than abrt, so it shouldn't hurt to try simply renaming that file. Abrt is for FOSS bug reporting. Those three blacklisted items NAICT are not FOSS.
