Yesterday i upgraded mutter:amd64 (42.5-0ubuntu1 to 42.9-0ubuntu1) and suddenly experienced the problem described in this thread. (black screen and logs like in #2)
After some investigation and finally finding this bug here adding MUTTER_DEBUG_USE_KMS_MODIFIERS=0 to /etc/environment fixed it for me, too. Seems like the bug was brought back somehow?

If I select 'Ubuntu on Xorg' - I can login without problems. If I select Wayland instead, I just get a black screen, and I have to kill gnome-session from a virtual console.
