Bug#942418: libmutter-5-0: Blank screen after upgrading to bullseye, caused by failing wayland

Tue Oct 15 23:35:22 BST 2019

Package: libmutter-5-0
Version: 3.34.1-1
Severity: critical
Justification: breaks the whole system

Dear Maintainer,

After upgrading from buster stable to bullseye testing and restarting, 
only a blank screen appears.
Problem caused by failing wayland, which is by default enabled since 
debian buster.
If wayland is disabled at /etc/gdm3/daemon.conf, the system started 
without problem,
but with newer  packages it only shows the logon-page, and after typing 
correct password it shows blank screen with working mouse pointer.
Problem occurs both at mutter 3.34.0-4 (testing) and mutter 3.34.1-1 
(unstable).

The log shows the next errors:
