Public bug reported:
Absolutely reproducible in Ubuntu 18.04.1 Gnome 3 UI with a Dell XP15
laptop and a Dell TB16 dock.
A few seconds after logging into the Gnome 3 UI, something in the UI
starts the fwupd.service. About 2 seconds later, the display goes blank
and does not come back. There is no obvious recovery short of killing
all the user's processes, and then logging back in. A second login does
not reproduce the problem, since the fwupd service is now running, and
does not restart. However manually restarting the fwupd service causes
the problem to recur.
The problem does not occur if the "dell" module is blacklisted in
/etc/fwupd/daemon.conf.
