I faced this issue after performing an upgrade on my system at around 5 PM (IST). The symptoms were all the same as stated in the comments above.
I don't know if this is a good workaround. But, what I did is sudo apt remove linux-image-4.15.0-24-generic linux- headers-4.15.0-24-generic And, this helped me get the system back. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1779827 Title: Started gnome display manager. dispatcher service To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1779827/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
