Upgraded from Fedora 25 to Fedora 26 and I am stuck at a login loop.
After a reboot, when i log in with GDM, screen goes black and returns to login screen.
If I Ctrl-Alt-F1 to a console and log in, return to login screen, I can then log in normally.
Affects wayland and gnome X sessions as well as LXqt .
It is NOT a selinux problem as it persists with selinux in permissive mode.
