I encountered the same problem today and after some trying around I came to the idea of changing the greeter, entered the first four commands of comment #9 (without having seen this bug report yet) and this way got back in again. Then I googled for the problem and found this bug report.
I am using a 2nd generation Lenovo X1 Carbon and during Artful development Wayland did not work for me and so I always worked in the "GNOME with Xorg" session. The greeter was LightDM (looked the same as the one of Zesty). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1722988 Title: Crash, black screen with lightdm To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1722988/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
