Same issue here. Just updated from Ubuntu GNOME 14.04 to Ubuntu GNOME 14.10 and it doesn't log into gnome; just a black screen. When I switch to the terminal it shows the following error:
systemd-logind[1148]: Failed to start unit user@1000.service: Unknown unit: user@1000.service -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1359439 Title: [ 7.287663] systemd-logind[1057]: Failed to start unit user@126.service: Unknown unit: user@126.service To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd-shim/+bug/1359439/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
