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?
