Following the steps in comment #4 I do not experience any freezing. It logs in successfully.
Next I suggest you ssh into the frozen machine and check: 1. If any processes are using high CPU. 2. How many gnome-shell processes are running. 3. Try to force the newest gnome-shell process (either running as you or as 'gdm') to dump core by sending it a fatal signal: kill -ABRT <PID-of-gnome-shell> If that works then you will have a crash file in /var/crash that we can analyse per comment #2. ** Changed in: mutter (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1878275 Title: wayland session hard freezes on login from GDM (X11 session works fine) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1878275/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
