Can you give a bit more details on what your environment is (you can use apport-collect 1565973).
Is unity8 even running? It sounds like you never get past the greeter - in which case logs from /var/log/lightdm might be helpful (clear it before you try logging in to the unity8 session). If unity8 is running - see, when it hangs, if you can Ctrl+Alt+F1 to a console, and/or reach it from the network (ssh). You could also try: $ apport-bug --hanging `pidof unity8` ** Changed in: unity8 (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/1565973 Title: Unity 8 freezes after log on To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity8/+bug/1565973/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
