Help me troubleshoot this:
When I launch a terminal from the menu using the fedora-28-dvm
template, I get a message that disp407 is starting, disp407 has
started, and disp407 has halted. No terminal comes up.
However, if I launch the browser (Firefox), it works fine.
If I run from dom0:
$ qvm-run --dispvm=fedora-28-dvm --service
qubes.StartApp+gnome-terminal
I get exactly the same starting/started/halted sequence, and no
error is reported.
