The gnome-session package must have libnm-gtk set as dependency. Otherwise gnome-session won't start missing NmGTK
Also reported under gnome-shell: https://bugzilla.redhat.com/show_bug.cgi?id=1509496 I discovered this today as well. I was trying to do a minimal install of Fedora with GNOME like so: 1. Use the netinstall ISO "Minimal install" option 2. dnf install gnome-shell @base-x 3. systemctl enable gdm.service 4. systemctl set-default graphical.target After bootup all I would get is a black screen and a cursor. Upon installing libnm-gtk, everything works fine.
Is this a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1509496 If so, it can probably be closed.
